Abstract
The present invention concerns new stable compositions of 1-Z-bromoalk-1-ene compounds of general formula (A). These compositions are characterized in that they also comprise either at least one cyclic ether compound comprising between 4 and 6 carbon atoms, or at least one ether of general formula (B) in which R1 and R2 are identical or different and selected from the group consisting of: a linear or branched alkyl group containing 1 to 8 carbon atoms.
Claims17
A composition comprising:
- a 1-Z-bromoalk-1-ene of general formula A:
- wherein R is a linear alkyl group having from 1 to 24 carbon atoms;
- and
- an ether which is:
- either a cyclic ether having a ring comprising from 4 to 6 carbon atoms, optionally substituted by a C1-C3 alkyl group,
- or an ether of general formula B:
- wherein n is from 1 to 4;
- m is from 0 to 5;
- and R1 and R2, identical or different, are selected from the group consisting of a linear or branched alkyl group having from 1 to 8 carbon atoms;
- wherein the 1-Z-bromoalk-1-ene has a content in the composition from 70 to 99.5% by weight based on the total weight of the composition.
