Improved process for preparation of sulfuric esters of higher alcohols.

摘要

Monounsaturated fatty alcohols are sulfated with minimal reaction at the double bond by using a multistage sulfation process in which the sulfating agent is chlorosulfonic acid, or a dioxane complex of chlorosulfonic acid or sulfur trioxide. The sulfation is carried out in a refluxing solvent medium, followed by ammonia or amine neutralization at each stage.
