Abstract
A process for the preparation of acetates of alcohols or phenols, in particular linalyl acetate, by causing alcohols or phenols to react with ketene in the presence of a catalyst, wherein the reaction is carried out using approximately equimolar amounts of linalool and ketene in the presence of a zinc salt of a carboxylic acid, or alternatively in the presence of a zinc compound which forms zinc acetate under the conditions of the reaction, and with vigorous mixing of the reaction mixture. Using this process, linalyl acetate and numerous other acetates interesting as perfumes or active agents can be obtained to a good degree of purity in yields of more than 90% of theory and in very good space-time yields.
