Abstract: The present invention is a process for producing organic esters wherein a dialkyl ether and a carboxylic acid are reacted in the presence of a solid phase acidic catalyst having an acidity factor of at least 0.30, preferably at least 1, under reaction conditions sufficient to form a reaction mixture comprising the desired organic ester and an alcohol and recovering the organic ester. For example, methyl acetate can be prepared by reacting dimethyl ether and acetic acid in the presence of montmorillonite, amorphous silica-alumina or .kappa.-alumina under conditions sufficient to form methyl acetate. While typical processes produce an azeotropic mixture of the desired organic ester and water, the claimed process utilizes a combination or reactants and catalysts wherein water is not produced in appreciable amounts. Therefore, the organic ester product can be separated conveniently thereby avoiding a cumbersome azeotropic distillation step as required in prior art processes.
