PROCESS FOR THE SYNTHESIS OF A SYMMETRIC ALPHA-OMEGA-DIFUNCTIONAL HYDROCARBON COMPOUND FROM OMEGA-OCTENOIC ALDEHYDE

摘要

The invention relates to a process for the synthesis of a linear symmetric alpha-omega-bifunctional hydrocarbon compound having the formula R1- (CH2) 5 -R2- (CH2) 5 -R1 in which R1 is -COOR3, R3 being either H is an alkyl radical comprising from 1 to 4 carbon atoms or -CH 2 NH 2 and R 2 represents an alkylene radical chosen between -CH = CH- and -CH 2 -CH 2 -, characterized in that in a first step the catalytic homometathesis of 7-octenal to form the alpha-omegadialdehyde of formula OHC- (CH2) 5-CH = CH- (CH2) 5-CHO and then, in a second step, this dialdehyde is subjected to either an oxidation reaction, or a In a third optional step, the ethylenic linkage is hydrogenated to form the saturated compound.
