실험 절차

In a separate reaction vessel was placed 560 grams of the above isomerized eicosene and 200 ml heptane. The 3.1 grams of tri-(3,5-di-tert-butyl-4-hydroxybenzyl)mesitylene stabilizer was added and the mixture heated to 210° C. Over a 2.5-hour period, 156.8 grams of maleic anhydride was added at about 225° C. Following this unreacted maleic anhydride was distilled out under vacuum at 210° C. leaving isomerized eicosenyl succinic anhydride.
