PROCESSO PARA A PRODUÇÃO DE CETONAS CÍCLICAS ALFA, BETA NÃO-SATURADAS ATRAVÉS DA DESIDROGENAÇÃO DE ÁLCOOIS ALÍLICOS CÍCLICOS SECUNDÁRIOS

摘要

A process for the manufacture of an alpha, beta-unsaturated cyclic ketone, such as carvone, comprises the dehydrogenation of a secondary allylic cyclic alcohol, such as carveol, in the presence of at least one metal carboxylate. The process can be performed in a batchwise or continuous mode. Examples of suitable metal carboxylates include magnesium stearate, calcium 2-ethylhexanoate, and zinc 2-ethylhexanoate.
