ABSTRACT:
This invention is directed to an improved method of recovering high purity N-acyl taurine in high yield. The recovery process involves solubilizing crude N-acyl taurine reaction product in a predetermined aqueous-alkanol solvent medium at an elevated temperature, then cooling the solution to a lower temperature whereat high purity N-acyl taurine crystallizes in high yield while salt and other impurities remain in solution, and thereafter filtering the crystalline material.
