Usage

General Description

N,N'-bis(dodecyldimethyl)-1,2-ethanediammonium, also known as 1,2-Bis(dimethyldodecylammonium)ethane dichloride, is a quaternary ammonium salt with two dodecyl groups attached to the nitrogen atoms. N,N'-bis(dodecyldimethyl)-1,2-ethanediammonium is used as a cationic surfactant and disinfectant agent due to its antimicrobial and antiviral properties. It is commonly used in industrial cleaning products, water treatment, and as a preservative in personal care products. Additionally, it is used in the synthesis of other cationic surfactants and can be a component in microemulsions and emulsion polymerization processes. However, caution must be taken when using this chemical, as it can be toxic to aquatic organisms and may cause irritation to the skin and eyes.

Micellization studies of dicationic gemini surfactants (m-2-m Type) in the presence of various counter- and Co-ions

Salts have the ability to influence the water activity and self-association of ionic micelles. In the present case, gemini surfactants; ethanediyl-α,ω-bis(dimethyl alkyl ammonium bromide) (referred to as m-2-m, m = 10, 12, 14) are synthesized and their micellization study in aqueous medium in presence of monovalent inorganic (NaBr, NaNO3, NaCl, KCl, LiCl) and organic salts (NaTos, NaBenz, NaSal) at 303 K is systematically investigated by conductometric and tensiometric methods. All the salts have the tendency to lower the critical micelle concentration of the surfactants. The effect of inorganic salts on the micellization properties has been found to obey the Hofmeister series. Organic salts reduce the CMC more effectively as compared to inorganic salts. The theoretical models of Rubingh and Rosen have been used to compare the results and obtain the interaction parameters, minimum area per molecule, surface excess, mixed micelle composition, activity coefficients and free energies of micellization/adsorption.

Adsorption of cationic gemini surfactants at solid surfaces studied by QCM-D and SPR: Effect of the rigidity of the spacer

Two small series of cationic gemini surfactants with dodecyl tails have been synthesized and evaluated with respect to self-assembly in bulk water and at different solid surfaces. The first series contained a flexible alkane spacer and is denoted 12-n-12,

A relative study on the micellization behavior of 12–2–12 Gemini surfactant with lactose and maltodextrin in aqueous medium: Spectroscopic and conductometric analysis

The present work reports the micellization mechanism and physico–chemical properties of synthesized 12–2–12 Gemini surfactant in aqueous solution of carbohydrates (lactose and maltodextrin) (0.0, 0.5, 1.0) % (w/v) at varying temperatures in the range (293.15–313.15) K. For this purpose, conductometric as well as spectroscopic measurements have been engaged to analyze the micellar modulation of Gemini surfactant in terms of its critical micelle concentration (CMC). The carbohydrates (lactose/maltodextrin) have been found to decrease the CMC of 12-2-12 Gemini surfactant, however, the effect is much more pronounced in maltodextrin as compared to lactose which is in compliance with the hydrophobic region present in the molecules. Further, temperature dependence of CMC has been employed to compute thermodynamic parameters of micellization in order to procure a better knowledge about the behavior of surfactant and intermolecular interactions present in such systems. The study of aqueous Gemini–carbohydrate systems may be helpful in working towards a healthier world from both personal as well as environmental aspects of life.

Study on cloud points of Triton X-100-cationic gemini surfactants mixtures: A spectroscopic approach

This study investigates the effects of various cationic surfactants on the cloud point (CP) of the nonionic surfactant Triton X-100 (TX-100) in aqueous solutions. Instead of visual observation, a spectrophotometer was used for measurement of the cloud point temperatures. The values of CPs for Triton X-100 can be measured directly because TX-100 has an average number of oxyethylene units per molecule of p ≈ 9.5 and a CP = 66.0 °C. Quaternary ammonium dimeric surfactants (m-s-m, m = 10, 12, and 16, and s = 2, 6, and 10) were synthesized and used. The melting temperature TM and the Krafft temperature TK were measured for 1 wt% aqueous solutions of these synthesized surfactants. The melting temperature of the solid gemini surfactants increased with the carbon number of the alkyl chain. The results showed that additions of the gemini surfactants (which are infinitely miscible with water) to Triton X-100 increased the cloud point of the TX-100 solutions. All salts tested in these studies had a large effect on the CPs of nonionic surfactants due to their effect on water structure and their hydrophilicity. The effect of the alkyl chain length of the gemini surfactant on the CP of Triton X-100 is therefore more important than the spacer chain length.

Synthesis and Physicochemical Properties of Double-Chain Cationic Surfactants

In this study two types cationic surfactants were synthesized, purified, and characterized in our laboratory. One them is a series of cationic surfactants, a two tail-one head surfactant, N,N-dialkyl-N,N-diethylammonium bromide, abbreviated as "m-0-m" (m = 10, 12, and 16). The other type is N,N′-dialkyl-N,N,N′,N′-tetramethyl-N,N′-ethanediyl-diammonium dibromide, two tail-two head surfactants, abbreviated as "m-2-m" (m = 12 and 16). Once NMR spectra (1H NMR, 13C NMR) for all the gemini surfactants that were synthesized were taken, then the melting temperatures (TM) were measured. These surfactants have very high surface activity. The main goal of our study was to examine some properties of these two tail cationic surfactants by manipulating their dimeric structure. The effects of alkyl chain length and headgroup on surfactant self-assembly in solution were investigated. Critical micelle concentrations (CMC), degree of micelle ionization (α), and Krafft temperatures (TK) of 1 wt % aqueous solutions of these surfactants were determined by conductance measurements. Krafft points were found to be dependent on the number of carbon atoms in the alkyl chain and decreased by the addition of the electrolytes. The absence of the spacer group, peculiar to these twin tail cationic surfactants, may confer relatively low flexibility to the molecules, with potential implications on the interfacial properties, namely, on micellization.

Effects of structure dissymmetry on aggregation behaviors of quaternary ammonium gemini surfactants in a protic ionic liquid EAN

The aggregation behaviors of a series of dissymmetric cationic Gemini surfactants, [CmH2m+1(CH3)2N(CH 2)2N(CH3)2CnH 2n+1]Br2, designated as m-2-n (with a fixed m + n = 24, m = 16, 14, 12) have been investigated in a protic ionic liquid, ethylammonium nitrate (EAN). Surface tension, polarized optical microscopy (POM), small-angle X-ray scattering (SAXS), and rheological measurements are adopted to investigate the micellization and lyotropic liquid crystal (LLC) formation. The obtained results indicate that the structure dissymmetry plays an important role in aggregation process of m-2-n. With increasing degree of dissymmetry, the critical micellization concentration, the maximum reduction of solvent surface tension, and the minimum area occupied per surfactant molecule at the air/EAN interface all become smaller. The thermostability of formed LLCs is therefore improved because of the more compact molecules. These characteristics can be explained by the enhancement of solvophobic effect due to the increased structure dissymmetry of Gemini surfactants.
