Sulphation of Unsaturated Fatty Alcohols.

When examining the reaction of unsaturated fatty alcohols with gaseous sulphur trioxide an addition of the primarily formed alkenyl hydrogen sulphates to double bonds was discovered. Sulphatet products formed in this way, which contain dialkyl sulphate groups, can be converted into alkenyl sodium sulphates by means of alkaline hydrolysis. For these processes, a reaction mechanism has been proposed on the basis of kinetic determinations. The by-product content was determined in the new products as well as in the products of sulphuric and chlorosulphonic acid sulphation, the quantitative proportion of by-products being related to the applicational properties.
