Abstract

PURPOSE: To prepare the title compound useful as a raw material of plastics, industrial chemicals, intermediate of medicines, pesticides, etc., without producing water, easily and selectively, only by the oxidation of the acetal of an aromatic aldehyde with hydrogen peroxide or an organic peracid.
CONSTITUTION: An aromatic aldehyde acetal of formula I or II (R, R' are 1W10C alkyl; n is 1W5; m is 2W4) (e.g. p-tolualdehyde.dimethylacetal) is oxidized with hydrogen peroxide or an organic peracid to obtain the objective compound of formula III or IV (e.g. p-cresol and formic acid ester of p-cresol). The organic peracid is pref. the one derived from a carboxylic acid having a degree of dissociation in water of >10-4 (e.g. formic acid).
EFFECT: The absence of water byproduction facilitates the separation, simplifies the operation, and reduces the separation energy.
