Process for producing methyl p-toluate |
摘要 |
P-Tolualdehyde freed from reaction-inhibiting 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 p-toluate at the same time. The foregoing reactions can be carried out easily and safely in simple processes in high yields.
