PROCESS FOR PRODUCING PER-P-TOLUIC ACID AND UTILIZING THE SAME

摘要

p-Tolualdehyde freed from reaction-inhibit-ing substances is autooxidized by a gas containing molecular oxygen in an aliphatic ketone or fatty acid ester solvent under pressure in the absence of catalyst to produce per-p-toluic acid. The resulting per-p-toluic acid is brought into contact with a lower olefin in the absence of catalyst to produce p-toluic acid and an alkylene oxide at the same time, or said per-p-toluic acid is reacted with allyl alcohol to produce glycidol and p-toluic acid at the same time, and further the resulting glycidol is hydrolyzed to produce glycerin, or said per-p-toluic acid is reacted with methanol in the presence of an esterification catalyst to produce hydrogen peroxide and methyl ptoluate at the same time. The foregoing reactions can be carried out easily and safely in simple processes in high yields.
