실험 절차
A mixture of α-phenyl-maleic anhydride (20 g, 0.115 moles), butadiene (40 g, 0.74 moles) and 200 ml of toluene was heated at 100° C. in a sealed bomb for 15 hrs. The toluene solution was decanted from an insoluble, polymeric material and evaporated in vacuo to yield crude 1-phenyl-4-cyclohexene-1,2-dicarboxylic acid anhydride, bp 155° (0.3 mm).
