FIELD: chemistry.
SUBSTANCE: invention relates to a method for synthesis of campholene aldehyde which is widely used in perfumery and household chemicals. The method involves conversion of α-pinene epoxide in a supercritical complex solvent consisting of a mixture of carbon dioxide, propanol-2 and water at temperature of 160-240°C and pressure of 130-220 atm. As a rule, the conversion reaction is carried out in a supercritical solvent with molar ratio water/α-pinene epoxide equal to 5-7.9.
EFFECT: method increases rate and efficiency of the chemical process to obtain an end product with high output and with controlled selectivity.
