反応手順

5 mol of o-tert-butylphenol was charged into a reactor, along with 400 ml of decane and 5% of 4,5-dihydro-2-phenylimidazole, and the mixture was heated to 140° C. Then 5.5 mol of diethyl carbonate was added portionwise over a period of 4 hr. The resulting ethanol was continuously removed by distillation from the reaction mixture. After completion of the reaction, 4.6 mol of o-tert-butylphenyl ethyl ether was obtained from the mixture by distillation. The yield corresponded to 92% of theoretical, based on the starting amount of o-tert-butylphenol.
