Unsaturated fatty alcohol derivatives from natural oil metathesis
Last updated:
Abstract:
Sulfate and sulfonate derivatives of unsaturated fatty alcohols, processes for making them, and methods of using them are disclosed. In one aspect, a monounsaturated fatty alcohol composition is made by reducing a metathesis-derived monounsaturated alkyl ester. The fatty alcohol composition is then converted to a sulfate or sulfonate derivative by one or more of alkoxylation, sulfation, sulfonation, and sulfitation. Of particular interest are the sulfate and ether sulfate derivatives.
