Refining methods and production of esters and dibasic acids from natural oils as raw material

摘要

Abstract "Methods of Refining and Production of Dibasic Esters and Esters from Natural Oils as Raw Materials" The present invention relates generally to methods and systems for producing dibasic esters and / or dibasic acids using metathesis. In some embodiments, the methods comprise reacting a terminal olefin ester with an internal olefin ester in the presence of a metathesis catalyst to form a dibasic ester and / or dibasic acid. In some embodiments, the terminal olefin ester or the internal olefin ester are derived from a renewable feedstock, such as a natural oil as feedstock. In some such embodiments, the natural oil as a feedstock or a transesterified derivative thereof is metathesically reacted to create the terminal olefin ester or the internal olefin ester.
