Manufacture of a charge director
Herein is described a method for the manufacture of a charge director comprising a barium salt. The method comprises reacting barium alkoxide with an acid in a reaction medium comprising ethanol, and separating ethanol from the reaction mixture to recover the barium salt produced.
Method for producing (E,Z)-7,9-dodecadienyl-1-acetate
The present invention concerns a method to access (E,Z)-7,9-dodecadienyl-1-acetate in two synthesis steps with excellent yields and selectivity greater than 70% by transformation of 2-hexenal into a novel intermediate, which is itself then transformed into (E,Z)-7,9-dodecandienyl-1-acetate.
