FIELD: chemistry.
SUBSTANCE: present invention relates to a method of producing α-terpineol, which can be used in manufacturing of perfume compositions, as well as a component of flavouring agents at production of detergent and cleaning agents. In disclosed method α-terpineol is prepared from technical terpineol obtained by hydration of sulphate α-pinene, crystallisation followed by separation of precipitated crystals. Crystallisation is carried out by a multi-stage countercurrent at 0-32 °C.
EFFECT: disclosed method increases output of end product and degree of extraction from mother solution.
