As a method for producing an N-acyl taurine compound, a so-called Schotten-Baumann method in which a corresponding taurine compound is reacted with a fatty acid halide in an aqueous NaOH solution is known (US Pat. No. 1932180, US Pat. No. 4,352,759). Etc.). However, as a result of the inventors of the present invention re-trying the production method by the Schotten-Baumann method, it is difficult to stir the reaction liquid because the solubility of the product N-acyl taurine metal salt in water is small, To uniformly stir the reaction solution, it is necessary to use a large amount of solvent or raise the reaction temperature. In either case, hydrolysis of the fatty acid halide is promoted and a large amount of by-product fatty acid is produced. It turns out that there is a drawback.

This was separated by filtration, washed with water, and dried to obtain 29.5 g of colorless crystals of sodium salt of N-lauroyltaurine (yield 85.3%). The purity of the obtained crystals is 74.
It contained 6% of sodium laurate 14.6% and sodium chloride 3.4%.
