실험 절차
A four-neck flask equipped with a stirrer, a temperature gauge, a nitrogen gas blowing tube and a water separator was charged with 89.8 g (1.0 mol) of dipentaerythritol (trade name: DiPentarit, manufactured by Koei Kagaku Co., Ltd), 86.2 g (2.0 mol) of benzoic acid (trade name: PuroxB, manufactured by DSM Company) and 424.0 g (4.0 mol) of hydroxystearic acid (trade name: Hydroxystearic acid, manufactured by Kawaken Fine Chemicals Co., Ltd) and the mixture was reacted using 0.6 g of tin chloride as a catalyst at 180° C. to 200° C. under a nitrogen stream for about 15 hours. After the reaction was finished, the reaction mixture was purified by a usual method, to obtain 391.6 g of the target ester compound of dipentaerythritol, and benzoic acid and 12-hydroxystearic acid, the ester compound having a saponification value of 211.
