【摘要】 以邻苯基苯酚和三氯化磷为起始原料,路易斯酸为催化剂,合成了新型阻燃剂[(6 氧 6H 二苯并 (c,e)(1,2) 氧磷杂己环 6 酮) 甲基] 丁二酸(DDP),测定了DDP在丙酮 水混合体系中的溶解度。结果表明,质量百分数0.6的丙酮 水溶液是DDP重结晶较为合适的溶剂,为产品的纯化提供了基础数据。更多还原

【Abstract】 Using ophenyl phenol and phosphorus trichloride as raw materials, and Lewis acid as catalyst, a new flame retardant )oxabutanedioic acid(DDP)is synthesized. Solubility of DDP in acetonewater mixed solvent is determined. The results showed that the concentration 60% acetonewater mixture is a right solvent for recrystallization, which offers basic data for purification of product.更多还原
