Surface-chemical study of an aqueous mixture of alpha-sulfolauric acid salts with cationics
The physicochemical properties of an aqueous mixture of alpha-sulfolauric acid (H2LS) and its various salts, including sodium alpha-sulfolaurate (NaHLS), triethanolammonium alpha-sulfolaurate (TeAHLS) with a cationic surfactant, decyltrimethylammonium bromide (DeTAB), have been investigated. The surface activities of H2LS and its salts were enhanced greatly in the mixed systems; e.g. for a 1:1 mixed solution, the cmc and gammacmc can be reduced from 1.4 ¡Á 10-2 mol dm-3 and 45 mN m-1 to 5 ¡Á 10-4 mol dm-3 and 24 mN m-1 respectively. The effect of inorganic electrolytes (NaBr and HBr) on the surface activity and the molecular interactions between the two surfactants in the mixed adsorption layer and micelles have been studied systematically. It was found that the phase separation concentrations (PSCs) of the mixed surfactant solutions are greater than the cmcs. For 1:1 NaHLS-DeTAB solution, PCS/cmc = 3.2. It is also revealed that, unlike the common anionic-cationic mixture, e.g. C10H21SO4Na-DeTAB, the mixed micellar solution is thermodynamically stable up to 3 ¡Á cmc.

The surface activities of H2LS and its salts were enhanced greatly in the mixed systems; e.g. for a 1:1 mixed solution, the cmc and gamma(cmc) can be reduced from 1.4 x 10-2 mol dm-3 and 45 mN m-1 to 5 x 10-4 mol dm-3 and 24 mN m-1 respectively.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: N,N,N-Trimethyldecan-1-aminium bromide, you can also check out more blogs about2082-84-0
