PRODUCTION OF HIGH MOLECULAR WEIGHT UNSATURATED KETONES

摘要

A process for the production of high molecular weight unsaturated ketones by alkylation of low molecular weight alpha , beta -unsaturated ketones with an allyl alcohol at elevated temperature in the presence of an acid catalyst. The products are intermediates for the production of various natural substances and perfumes such as the damascenones, damascones or natural dyes such as zeaxanthin, rhodoxanthin or xanthophyll.
