Title: NOVEL COMPOSITION OF 7,9-DODECADIENYL-1-ACETATE ISOMERS AND PROCESS FOR PRODUCTION THEREOF
Abstract:
The present invention relates to a process for preparing a mixture M1 of enol phosphate isomers devoid of (E,E) isomer and comprising at least 98% of (E,Z) isomer, at least 0.1% of (Z,Z) isomer and at least 0.1% of (Z,E) isomer, comprising bringing a mixture of isomers of said enol phosphate comprising a detectable amount of (E,E) isomer into contact with a hydrolysable dienophile in an organic solvent, followed by base hydrolysis of the medium obtained and elimination of the adduct formed, in order to obtain the mixture M1 devoid of (E,E) isomer.
