Abstract

Alkali metal acyl taurides of the formula: <FORM:0783038/IV (a)/1> wherein R is a hydrocarbon radical of 10 to 24 carbon atoms, R1 is hydrogen or an alkyl radical of 1 to 4 carbon atoms and M is an alkali metal, are prepared by continuously intermingling with violent agitation a first reactant stream comprising an acyl chloride of the formula R.COCl, and a second reactant stream comprising an aqueous solution of an alkali metal hydroxide and an alkali metal tauride of the formula: <FORM:0783038/IV (a)/2> and continuously withdrawing the reaction product. The reaction may be carried out within the temperature range 20 DEG to 100 DEG C., preferably between 60 DEG and 88 DEG C. The molar ratio of alkali metal hydroxide to alkali metal tauride is usually at least 1.1 : 1 and preferably 1.2 : 1. The pH of the reaction mixture is preferably between 7 and 10. The alkali metal tauride is preferably sodium methyl tauride and the alkali metal hydroxide is preferably sodium hydroxide. If desired sodium chloride may be present in the tauride/hydroxide feed. The examples describe the acylation of sodium methyl tauride with (1) a mixture of 80 per cent palmitic and 20 per cent oleic acid chlorides, and (2) a mixture of 76.5 per cent palmitic, 18.4 per cent oleic and 5.1 per cent stearic acid chlorides.
