Abstract
The invention concerns a process for directly converting an aldehyde into an ethylene ester, of the type wherein the aldehyde is placed in the presence of an alkaline carbonate or bicarbonate and of a phosphonate into a solvent with an alcohol function. In the invention, an ethyl phosphonate or a methyl phosphonate is used and the solvent is an alcohol or a polyol including a hydrocarbon radical other than ethyl or methyl, this radical being that of the ethylenic ester to be produced. The process of the invention makes it possible to directly convert furan aldehyde or tetrahydrofuran aldehyde to produce an ethylenic ester with a furan ring or a tetrahydrofuran ring.
