Densities, conductivities, and aggregation numbers of aqueous solutions of quaternary ammonium surfactants with hydroxyethyl substituents in the headgroups

The aggregation behaviors of two cationic surfactants, namely, N-dodecyl-N-2-hydroxyethyl-N,N-dimethyl ammonium bromide (C12HDAB) and N-dodecyl-N,N-2-dihydroxyethyl-N-methyl ammonium bromide (C 12DHAB), were studied by measurements of density, conductivity, and steady-state fluorescence quenching. The aggregation number, the volumetric properties, and the standard Gibbs energy (ΔGmic0) of micellization were obtained, and the surface area (Amic) of the surfactant headgroups and the radius (r) of the micelles were estimated. It was found that substituting the methyl group with the hydroxyethyl group in the head of the surfactant led to the increase of the volume change of micellization and the decreases of the critical micelle concentration, association degree of the counterion, and the value of ΔGmic0, while the aggregation number of those surfactants in aqueous solutions was little affected by introducing the hydroxyethyl group. It was also found that the values of A mic and r increase with the hydroxyethyl group.

Synthesis, surface properties and inhibition behavior of novel cationic gemini surfactant for corrosion of carbon steel tubes in acidic solution

In the present investigation a novel gemini surfactant namely N,N-((oxalylbis(oxy))bis(ethane-2,1-diyl))bis(N,N-dimethyldodecan-1-aminium bromide) was synthesized, characterized, and tested as a corrosion inhibitor for carbon steel in 1 M HCl solution. The corrosion inhibition efficiency was determined by using electrochemical impedance spectroscopy (EIS), potentiodynamic polarization, and weight loss methods. From the results, it was clear that the synthesized inhibitor is a good inhibitor for carbon steel in 1 M HCl solution. The inhibition efficiency increases by increasing the concentration of the inhibitor. Thermodynamic and activation parameters were discussed. The synthesized inhibitor's adsorption was found to follow the Langmuir's adsorption isotherm.

Sulfidogenic-corrosion inhibitory effect of cationic monomeric and gemini surfactants: Planktonic and sessile diversity

A cationic monomeric surfactant (CMS) and a cationic gemini surfactant (CGS) were successfully synthesized and characterized. A comparison of the CMS and CGS metal corrosion inhibitory effects was carried out on the basis of protecting a metal surface from cultivated salinity (3.18% NaCl) and an environmental sulfidogenic bacterial activity in a reactor's bulk phase (planktonic) and on a metal surface (sessile). Environmental sulfidogenic bacterial consortia were originated from an oil-field water tank. The sulfidogenic bacterial activities were evaluated based on redox potential and sulfide concentrations in the reactor's bulk phase. In addition, changes in biofilm structures and constituents and the metal corrosion rate were determined to estimate changes on metal surfaces. Results in the reactor's bulk phases showed that at high surfactant (CMS, CGS) concentrations, a considerable decline in the redox potential was observed and the sulfide productivity was completely suppressed. The synthesized surfactants showed the highest metal corrosion inhibition efficiencies of 92% and 94% at concentrations of 10 mM and 1 mM for the CMS and the CGS, respectively. In addition, the synthesized CMS and CGS showed nonspecific antibacterial activity against Gram-positive and Gram-negative bacterial-standard strains.

Cationic Gemini surfactant as a corrosion inhibitor and a biocide for high salinity sulfidogenic bacteria originating from an oil-field water tank

A novel cationic gemini surfactant (NCGS) was synthesized and characterized. The inhibitory effect of NCGS was evaluated on the basis of protecting a metal surface from the salinity (5.49 % NaCl) and the activity of environmental sulfidogenic bacteria which originated from an oil-field water tank. Sulfidogenic bacterial activities were determined based on sulfide production, redox potential, changes in biofilm structures and constituents and metal corrosion rate calculations. At high surfactant concentrations, the sulfide production was completely inhibited as well as a considerable drop in the redox potential was observed in the reactor's bulk phase. A minimum inhibitory concentration of the NCGS was achieved at a concentration of 1 mM. The NCGS showed a high ability to inhibit a biofilm over the metal surface at a concentration of 0.1 mM. The lowest metal corrosion rate was detected at a concentration of 5 mM with a metal corrosion inhibition efficiency of 97 %. In addition the NCGS showed a nonspecific biocidal activity against Gram-positive and Gram-negative bacterial strains.

Chemical, electrochemical, theoretical (DFT & MEP), thermodynamics and surface morphology studies of carbon steel during gas and oil production using three novel di-cationic amphiphilies as corrosion inhibitors in acidic medium

Three di-cationic amphiphilies were synthesized and characterized by FTIR, (1H & 13C) NMR spectroscopies. These compounds are tested as corrosion inhibitors for CS in 1 M HCl by weight loss (WL), EIS, potentiodynamic polarization (PP) techniques, and surface morphology (SEM & AFM). Surface tension results exhibited that these surfactants are a good surface attitude in their aqueous media. The gained results exhibited that the di-cationic surface-active agents are stellar deterioration inhibitors for CS in 1 M HCl. A discouragement efficacy augmented with increment of the inhibitor concentration. Adsorption of CSI, CSII & CSIII on CS in 1 M HCl was established to comply with Langmuir's adsorption isotherm. SEM & AFM photos exhibit a good CS surface in presence of CSI, CSII & CSIII in opposite of the absence of them. The inhibition mechanism is suggested on the thermodynamic factors. The inhibitive impact of the explored surfactants against the corrosion of the CS surface was implied by DFT/6-31G(d,p) computations.

The Effect of Polar Head and Chain Length on the Physicochemical Properties of Micellization and Adsorption of Amino Alcohol-Based Surfactants

In this work, we have synthesized a series of quaternary ammonium from amino alcohols and n-bromoalkanes. The compounds are referred to as CnEtOH, CnPrOH, and CniPrOH (where n = 12 and 14 carbons, EtOH = ethanol, PrOH = propanol, iPrOH = iso-propanol). Their structures were checked using the usual spectroscopic methods [1H, 13C nuclear magnetic resonance (NMR) and infrared (IR)]. Their physicochemical properties in aqueous solution were studied using conductivity, surface tension, and ultra violet (UV)–visible absorption spectroscopy measurements. This study was conducted to show the effect of the linear hydrophobic chain and the location of the OH polar group with respect to the N+ quaternary ammonium on the physicochemical properties of the surfactants. The comparison between the physicochemical properties of the surfactants studied shows a distinct effect of the position of the OH group on the critical micelle concentration (CMC), the ionization degree (a), the area occupied at the interface (Amin), the free energy of adsorption (ΔG0ad), and the free energy of micellization (ΔG0M). The intermolecular interaction between the synthetic surfactants and the methyl orange (OM) dye is related to the degree of hydration of the micelle, proven by the hypsochromic displacement of OM wavelength (?max) and ionization (a) of the micelles. The CMC, the degree of ionization, and the degree of hydration of the micelle follow the same trend.

Method of catalyzing conversion of CO2 with alcohol amine bromide ionic liquid to synthesize cyclic carbonate compound

The invention discloses a method of catalyzing conversion of CO2 with alcohol amine bromide ionic liquid to synthesize a cyclic carbonate compound and belongs to the technical field of synthesis of cyclic carbonate compounds with catalysis of ionic liquids. The method is characterized in that: by taking the alcohol amine bromide ionic liquid as a catalyst, an ethylene oxide compound and CO2 are catalyzed at the atmospheric pressure and 90 DEG C to perform cycloaddition reaction to prepare the cyclic carbonate compound as a target product, and the alcohol amine bromide ionic liquid is repeatedly used after being recovered. In the method, the used alcohol amine bromide ionic liquid is simple and convenient to prepare and has good biocompatibility; the catalyst is high in catalytic activity and good in selectivity; and a reaction system does not have special requirements on a reaction vessel, and operation and the aftertreatment process of a catalytic system are relatively simple.

Plasma membrane permeabilisation by ionic liquids: a matter of charge

Understanding the mechanisms of toxicity of ionic liquids at the molecular level is crucial for their conscious design as to promote higher acceptability as green solvents in a wide range of applications. In this systematic study, we investigated the effects of three families of ionic liquids on the plasma membrane of the filamentous fungus Aspergillus nidulans. Using fluorescence microscopy and gene expression analysis, we were able to demonstrate that the widely studied 1-alkyl-3-methylimidazolium chlorides with long alkyl substituents cause membrane permeabilisation. In opposition, the biocompatibility of cholinium alkanoates was reinforced here, even though their toxicity also increases with the elongation of the anion. Further investigating the effects of charge on membrane permeabilisation, we observed that a series of alkyl-(2-hydroxyethyl)-dimethylammonium bromides led to permeabilisation of the fungal plasma membrane by increasing the length of one alkyl substituent in the cholinium cation. We hypothesise that the chemical nature of the plasma membrane, which presents a heterogeneous charge distribution along its surface, is pivotal for the membrane permeabilising effects of ionic liquids. This study may inspire a new trend in the ionic liquid field: to give preference for the development of compounds carrying functionalised anions as greener alternatives to those carrying functionalized cations.

Alginate surfactant derivatives as an ecofriendly corrosion inhibitor for carbon steel in acidic environments

Biopolymer alginate surfactant derivatives were synthesized and their influences as a novel corrosion inhibitor on carbon steel in 1 M HCl were studied using gravimetric, electrochemical, EDX and SEM techniques. The compounds obtained were characterized using FTIR, 1H NMR and UV-vis spectroscopy studies. The inhibition efficiency increased with the increase in concentration and reached a maximum of 96.27% for AS-Cu at 5 × 10-3 M concentration. Potentiodynamic polarization results reveal that alginate derivatives could be classified as mixed-type corrosion inhibitors with predominant control of the cathodic reaction. The extent of inhibition exhibits a positive trend with an increase in temperature. The Langmuir isotherm provides the best description of the adsorption nature of the inhibitor. The results of EIS indicate that both the charge transfer resistance and inhibition efficiency tend to increase by increasing the inhibitor concentration. The thermodynamic parameter and activation parameters were calculated to investigate the mechanism of inhibition. Also, the relationship between the chemical structure and inhibition efficiency of the inhibitor was discussed.

Synthesis, characterization and conductivity of quaternary nitrogen surfactants modified by the addition of a hydroxymethyl substructure on the head group

Two novel series of hydroxymethyl group-appended quaternary nitrogen surfactants (QNSs) based on the aliphatic N-alkyl-trimethylammonium and aromatic N-alkylpyridinium head groups were synthesized from the appropriate nitrogen head group precursor and 1-bromoalkane. The QNSs were characterized using 1H and 13C nuclear magnetic resonance and infrared spectroscopy, and their purity confirmed using elemental analysis. The solution behavior of the QNSs was investigated by conductivity, assessing both the aggregation concentration as well as the amount of counter-ion dissociation. The results showed a general decrease in the aggregation concentration for the compounds with the hydroxymethyl addition, where the pyridinium compounds were more affected than the ammonium QNSs. In contrast, the extent of counter-ion dissociation (α) from the aggregate was slightly increased for the ammonium compounds but that of the pyridinium compounds was not generally affected by the structural modification.
