性质描述: 淡黄色结晶。熔点139-140℃。溶于乙酸乙酯、甲乙酮和甲苯,不溶于水。
生产方法: 由间苯二甲醚与光气缩合,然后用碱水解,再经酸化而得。
用途: 该品为二苯甲酮类紫外线吸收剂。紫外线吸收剂是目前使用最普遍的光稳定剂,这是一类能够强烈地、选择性地吸收高能量的紫外光,并进行能量转换,以热能形式或无害的低能辐射将能量释放或消耗的物质。含有一个邻位羟基的二苯甲酮只吸收380nm以下的紫外光,几乎不吸收可见光。该品在270-380nm波长范围内有强烈吸收,适用于聚氯乙烯、丙烯酸树脂、环氧树脂、酚醛树脂、硝酸纤维素和聚氨酯类。但该品可吸收一部分可见光,使制品稍带黄色。对大白鼠口服LD50为3000mg/kg。
