AMINO ACID PREPARATION METHOD COMPRISING A STEP OF HYDROFORMYLATION OF AN UNSATURATED FATTY NITRILE

摘要

A method for synthesizing a ω-amino acid compound having formula HOOC—R′—CH2NH2, where R is an alkyl radical including between 6 and 15 carbon atoms or an alkylene radical including between 6 and 15 carbon atoms and between 0 and 2 unsaturations. The method including the following steps: 1) hydroformylation of an unsaturated fatty nitrile selected from compounds having formula R1—CH═CH—[(CH2)q—CH═CH]m—(CH2)r—CN, said step consisting in reacting the nitrile with the carbon monoxide and dihydrogen such as to obtain at least one fatty nitrile aldehyde having formula HOC—R′—CN; 2) dioxygen oxidation, wherein the nitrile aldehyde obtained in step 1) is converted into fatty nitrile acid having formula HOOC—R′—CN; and 3) reduction, in which the nitrile acid obtained in step 2) is converted into co-amino acid having formula HOOC—R′—CH2NH2.
