Patent ID: 7846886

Claim:
A composition comprising a mixture of isomers of 17-oxabicyclo[14.1.0]heptadec-8-ene, having a content of an (E)-17-oxabicyclo[14.1.0]heptadec-8-ene isomer (1) and/or (2), wherein a) if the isomer mixture contains four isomers (1), (2), (3) and (4), the content of isomer (1) is greater than 32 wt. % and/or the content of isomer (2) is greater than 12 wt. %, b) if the isomer mixture contains only two or three isomers chosen from the isomers (1), (2), (3) and (4), the content of isomer (1) and/or isomer (2) is at least 45 wt. %, in each case based on the total weight of the isomer mixture.
