Title:
METHOD FOR SYNTHESIZING CARVACROL BY CATALYZING DIHYDROCARVONE ISOMERIZATION
Document Type and Number:
WIPO Patent Application WO/2019/019808
Kind Code:
A1
Abstract:
The present invention discloses a method for synthesizing carvacrol by catalyzing dihydrocarvone isomerization, wherein Cu/Cr is used to catalyze the dehydroisomerization of dihydrocarvone so as to synthesize carvacrol; after the reaction is finished, the catalyst particles and the product are easy to separate, and same can be recycled many times and the catalytic efficiency thereof stays basically unchanged; and the reaction conversion rate is high, and none of the industrial three wastes are produced. In addition, the catalyst in the invention is cheap and easy to obtain, the process is simple, green and non-polluting, and same is more suitable for the industrial-scale production of carvacrol.
