反应详情

A solution of 10 g of dodecyl 4-hydroxybenzoate and 60 ml of acetic acid was heated at 30° to 35° C. and a solution of 2 ml of fuming nitric acid and 10 ml of acetic acid was added dropwise thereto over a 20 minute period with stirring. After the completion of the addition, the mixture was stirred for 1 hour. The crystals deposited in the reaction mixture were collected by filtration, washed with water and recrystallized from ethanol to obtain 11.0 g (yield 95.8%) of the desired compound having a melting point of 70° C.
