| abstract | 1,174,857. Olefinic sulphonates. COLGATEPALMOLIVE CO. 13 July, 1967 [2 Aug., 1966], No. 32242/67. Heading C2C. Olefin sulphonates are prepared by reacting diluted gaseous sulphur trioxide and an olefin to produce an acid mix, neutralizing the acid mix with an aqueous alkaline material while maintaining the temperature below 150‹ F., the amount of alkaline material and water being such that the resulting blend has a pH of at least 12 and a viscosity of at least 5000 centipoises, and passing the viscous alkaline blend continuously into a zone maintained under super atmospheric pressure in which the blend makes contact with a heated solid heatexchange surface maintained at a temperature of at least 350‹ F. so as to raise the temperature of the blend to at least 330‹ F. within a period of less than 5 minutes. The alkaline material is generally used in a quantity of 110-140% of the stoichiometric amount required. Suitable olefins are R-CH=CH-R<SP>1</SP>, where R is alkyl and R<SP>1</SP> may be alkyl or preferably hydrogen, and contain 8-30 C atoms. The acid mix may also be prepared by reacting the SO 3 /olefin product with concentrated H 2 SO 4 . |
