Abstract:
A process for producing esters from aldehydes comprising reacting essentially in the absence of water an aldehyde having the general formula of RCHO, R being an alkenyl group or alkyl group having one to six carbon atoms, with an oxidizing agent having the general formula Râ€²3COX, wherein Râ€² is an alkyl group having one to six carbon atom bonded to a tertiary carbon atom, each Râ€² being the same or different, and wherein X is a halogen, to form an intermediate which is reacted with an alcohol having the general formula of Râ€³OH wherein Râ€³ is an alkyl group or an alkoxy group having one to eight carbon atoms or is an aryl group having six to ten carbon atoms or with a diol having the general formula HORâ€²â€³OH wherein Râ€²â€³ is an alkyl group having one to eight carbon atoms or is an aryl group having six to ten carbon atoms to form an ester having the general formula RCOORâ€³ or RCOORâ€²â€³OH or a diester having the general formula RCOORâ€²â€³OOCR, wherein a base is optionally added before, during or after the alcohol or diol and the base is an inorganic base.
