PREPARATION OF SULPHATES

摘要

Secondary monoalkyl sulfuric acids are obtained in high selectivity and at a fast reaction rate in a process wherein C8 to C22 olefins are sulfated with sulfuric acid in the presence of a large amount of added secondary C8 to C22 alcohols. Additionally, the resulting sulphation reaction effluent containing secondary monoalkyl sulfuric acids may be neutralized to prepare the salts thereof, in which case the alcohols in the neutralization reaction product are recovered and recycled to the sulfation reaction zone.
