Versuchsvorschrift
45 Parts of 2,4,6-trimethylphenol, 10 parts of sodium hydroxide, and 150 parts of water were fed to a stainless steel autoclave equipped with a gas-introducing pipe, temperature recorder and stirrer, and 100 Kg/cm2G oxygen pressure was applied. The reaction was conducted at 30°C. for 120 minutes, during which the pressure was reduced to 83 Kg/cm2G. The reaction product was recovered and extracted 2 times with 150 g of benzene with shaking. Analyses of benzene parts and water parts yielded 31.130 parts of 4-hydroxy-2,4,6-trimethyl-2,5-cyclohexadiene-1-one and 3.866 parts of unreacted 2,4,6-trimethylphenol from the benzene parts. 0.705 Parts of 4-hydroxy-2,4,6-trimethyl-2,5-cyclohexadiene-1-one and 0.090 parts of unreacted 2,4,6-trimethylphenol were also yielded from the water parts. Analyses of the results proved 91.2 % of conversion and 69.4 % of selectivity. Expelling the benzene out of said benzene solution and concentrating the benzene, 34 parts of oily product was obtained. The oily product was analyzed to be composed of 92.2 % of 4-hydroxy-2,4,6-trimethyl-2,5-cyclohexadiene-1-one and 9.6 % of 2,4,6-trimethylphenol.
