Abstract
PURPOSE: To advantageously obtain the titled substance which is a synthetic intermediate of musk or perfume substance while safely recovering a generation gas, etc., by subjecting a halogenated brassylic acid dilower alkyl ester of a raw material which is readily available and inexpensive to hydrocracking with Raney nickel in the presence of a tert. amine.
CONSTITUTION: Hydrocracking reaction is carried out by using a halogenated brassylic acid di-lower alkyl ester as a raw material in the presence of Raney nickel and a tert. amine (preferably tri-n-butyl amine) in a solvent such as methanol, isobutanol, etc., to provide the aimed compound. The reaction is carried out using an autoclave at hydrogen pressure of 1W20kg/cm2, preferably 5W15kg/cm2 and about 50W100°C, preferably 70W80°C. A 2-halogenated brassylic acid di-lower alkyl ester which is a raw material compound is synthesized from an undecylenic acid ester obtained by thermal decomposition of castor oil and monohalogenated acetic ester.
