Process for preparing organic esters

Abstract

The present invention relates to a process for preparing an ester having formula R—COO—R′ (I), wherein R represents a group selected from: (i) a linear or branched alkyl, containing from 1 to 20 carbon atoms, (ii) an aryl containing from 6 to 12 carbon atoms, (iii) a heterocycle with 4 to 12 carbon atoms containing at least one heteroatom selected from O, N, P and S, R′ represents a linear or branched alkyl containing from 1 to 12 carbon atoms, said process comprising at least a phase of reacting a reaction mixture comprising at least one aldehyde having formula R—CHO (II), wherein R has the meanings defined above, and at least one alcohol having general formula R′—OH (III), wherein R′ has the meanings defined above, in the presence of at least one solid basic catalyst, at a temperature within the range of 120° C.-300° C., obtaining said ester having formula (I).
