Abstract
The invention relates to a method of enhancing conversion of alkali metal salt, preferably aqueous salt, preferably aqueous sodium salt of N-methyl taurine to alkyl taurate amides. In one aspect, the starting salt is pre-concentrated (at least 75% up to 99% taurine salt in the aqueous solutions after water is removed from a starting aqueous solution of the salt) and, in another aspect, the starting salt is not pre-concentrated.
