Versuchsvorschrift

Ethenolysis comprises a cross-metathesis reaction involving ethene. According to some preferred embodiments of the invention, a mixture of ethyl esters of Palmitoleic acid (C16:1) and Oleic acid (C18:1) are subjected to conditions of ethenolysis to yield a mixture of α-olefins (1-Octene and 1-Decene) and Methyl 9-Decenoate. See FIG. 8. The 1-Octene is a product unique to ethenolysis of Palmitoleic acid (C16:1). In the inventive method, Ethyl 9-Decenoate and 1-Decene will also form from the mixture of Palmitoleic and Oleic acid ethyl esters. Prior art methods using Oleic acid esters (Methyl Oleate) as the starting material only produce Methyl 9-Decenoate and 1-Decene.
