Abstract
A process for the preparation of keto-ethers having the general formula ** (See formula) ** where R and R 'have the meaning indicated below, which comprises reacting in a liquid phase, at a temperature between 0 and 100º C, a primary alcohol ROH, in which R is a primary hydrocarbon group containing from 1 to 5 carbon atoms, whose hydrocarbon group may be substituted with one or more substituents which are not reactive under the process reaction conditions, with an alpha, beta-unsaturated alkenone containing up to 10 carbon atoms and having the formula ** (See formula) ** wherein each R 'group is a hydrogen atom or an alcohol group, in the presence of a strongly basic anion exchange resin as a catalyst.
