  • Preparation of monoalkyl sulfuric acids and their salts
    Patent number: 4226797
    Abstract: Secondary monoalkyl sulfuric acids are obtained in high selectivity and at a fast reaction rate in a process wherein C.sub.8 to C.sub.22 olefins are sulfated with sulfuric acid in the presence of a large amount of added secondary C.sub.8 to C.sub.22 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.
