Usage

Uses

3-(N,N-Dimethyloctadecylammonio)propanesulfonate in combination with bis(2-ethylhexyl) sulfosuccinate sodium salt (AOT) forms an organic mixed micellar phase, which may be used for the extraction of erythromycin from the aqueous phase. The extraction performance and other parameters affecting erythromycin solubilization are evaluated.

General Description

3-(N,N-Dimethyloctadecylammonio)propanesulfonate is a zwitterionic surfactant, useful in membrane solubilization studies. It does not absorb UV light, hence interference with spectrophotometric analysis of proteins can be omitted.

Synthesis, characterization and surface properties of series sulfobetaine surfactants

A series of surface active sulfo-propane betaines and sulfo-butane betaines were synthesized with high yields by the reaction of an appropriate N,N-dimethyl alkylamine with an excess of 1,3-propane sultone and 1,4-butane sultone. The structures were characterized by 1H-NMR spectroscopy and elemental analysis. The micellar properties of these compounds were determined by surface tension methods. Surface tension measurements also provide information about the dependence of the surface tension at the CMC (γcmc), pC20 (negative logarithm of the surfactant molar concentration C20 required to reduce the surface tension by 20 mN/m), the surface excess (Γmax) at air/solution interface, the minimum area per surfactant molecule at the air solution interface (A).
