The invention relates to a process for improving the conversion of an alkali metal salt, preferably an aqueous salt, preferably an aqueous sodium salt of N-methyl taurine to alkyl amide taurate. In one aspect, the starting salt is pre-concentrated (at least 75% up to 99% taurine salt in the aqueous solutions after removal of water from an aqueous starting solution of the salt) and, according to one embodiment, In another aspect, the starting salt is not pre-concentrated. |
