Abstract
PURPOSE: To obtain the titled compound useful as an epoxydizing agent, initiator for radical reaction, crosslinking accelerator, etc. in high yield in stable state, by oxidizing 2,4,6-trimethylphenol with molecular oxygen in an aqueous solution with a specific pH at low temperature.
CONSTITUTION: 2,3,6-Trimethylphenol is subjected to contact reaction with molecular oxygen or a molecular oxygen-containing gas in an aqueous solution with a pH of 8W10 at 0W100°C, preferably at 20W50°C, to give 4-hydroperoxy-2,4,6- trimethyl-2,5,-cyclohexanediene-1-one. When the conversion is raised too extremely, the hydroperoxide is decomposed, not only the selectivity is reduced, but also a quinone type neutral substance and a high polymer substance are produced, and purification is not carried out easily. Consequently, the conversion is made 60W95%, and, if necessary preferably the unreacted raw material is recovered.
