abstract |
Case 6151 (2) ABSTRACT OF THE DISCLOSURE PREPARATION OF SURFACTANTS Alkyl-, aryl-, or alkylaryl-alkoxy ethane sulphonates are prepared by reacting the corresponding halides with potassium or ammonium sulphite in the presence of water in amount less than 50% by weight of the alkoxy ethane halide. Reducing the water content of the reaction mixture to a low level increases the throughput and yield and reduces the increase in viscosity of the reaction mixture as the reaction proceeds. |
