Usage

General Description

Dodecyl(2-hydroxyethyl)dimethylammonium bromide, also known as DHEMDAB, is a quaternary ammonium compound that is commonly used as a cationic surfactant and disinfectant in various industries. It is a nitrogenous cationic lipid molecule with a long hydrophobic tail and a positively charged hydrophilic head. DHEMDAB is known for its strong antimicrobial properties and is often used in the formulation of cleaning and disinfecting products. It is effective against a wide range of bacteria, fungi, and viruses, making it a popular ingredient in household cleaners, industrial disinfectants, and personal care products. Additionally, DHEMDAB is also used in the pharmaceutical industry for its ability to solubilize and deliver drugs to targeted areas. However, it is important to handle this chemical with caution as it can be irritating to the skin and harmful if ingested or inhaled.

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.

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.

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.

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

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.
