NEW TECHNOLOGY OF CATALYTIC SYNTHESIS OF DIHYDROMYRCENOL FROM PINANE

Dihydromyrcene was obtained from cracking of cis pinane,followed by direct hydration of the crude products to prepare dihydromyrcenol. Catalytic cracking of pinane was obviously superior to thermal cracking. When cis pinane was converted completely, the selectivity of dihydromyrcene was over 50% while that of thermal cracking is much lower. The selectivity of direct hydration of dihydromyrcene catalysed by solid acid was 80%, It had advantages of few kinds of auxiliary materials, short production period, low consumption, low pollution, etc.
