METHOD OF PRODUCING α-CAMPHOLENE ALCOHOL Russian patent published in 2012 - IPC C07C33/12 C07C29/56

Abstract RU 2461540 C1

FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing -campholene alcohol which possesses valuable organoleptic properties and can be used in perfume manufacturing. The method involves conversion of -pinene epoxide using a heterogeneous catalyst in a flow-type tubular reactor in a supercritical two-component solvent, which contains CO₂ and isopropyl alcohol at temperature 180-200°C and pressure 110-180 atm. As a rule, the heterogeneous catalyst used is [Co(2,6-Me₂C₅H₃N)₂Br₂]/Al₂O₃ or [Zn(2,6-Me₂C₅H₃N)₂Br₂]}/Al₂O₃.

EFFECT: method enables to efficiently obtain the end product in a single preparative step with high output over a contact time of a few minutes.
