Abstract:
A process for the production of an aldehyde comprising:providing a compound of formula R1â€”CX , wherein X is a group that leaves upon oxidation; reacting R1â€”CX and a source of oxygen to form R1â€”COH , wherein the reacting occurs in the vapor phase at a temperature of from 100Â° C. to 200Â° C. and in the presence of a catalyst consisting essentially of one or more of copper oxide and copper esters, wherein R1 is phenyl, which is unsubstituted or substituted by one or more identical or different radicals selected from (C1-C12)-alkyl, (C1-C12)-alkoxy, (C1-C12)-alkanoyloxy, (C1-C12)-alkanoyl, amino, hydroxyl, â€”CH2â€”Oâ€”(C1-C12)-alkyl, â€”NHâ€”(C1-C12)-alkyl, â€”NHâ€”COâ€”(C1-C12)-alkyl, or â€”Sâ€”(C1-C12)-alkyl; and separating the R1â€”COH.
