Abstract

A simple process for the manufacture of benzaldehyde (BzH) by oxidation of dibenzyl ether (DBE) has been reported in this paper. Two-phase reaction between dibenzyl ether and aqueous dilute nitric acid in the presence of catalytic amount of sodium nitrite has been investigated. Effect of stirring speed, concentration of nitric acid in the aqueous phase, mole ratio of reactants, sodium nitrite concentration, and reaction temperature on the conversion of DBE and yield of BzH has been investigated. 80% yield of BzH with 95% conversion of DBE has been reported. Oxidation of bis(chlorobenzyl) ethers to corresponding aldehydes is difficult compared to oxidation of DBE under otherwise identical conditions. Initial concentration of sodium nitrite does not affect the overall progress of the reaction.
