性质描述: 白色棱形结晶,熔点43℃,沸点360℃,218℃(2.67kPa),180℃(0.67kPa),相对密度1.1989(15/4℃),折光率1.5767(15℃)。溶于醇,醚、氯仿、丙醇、冰醛酸、苯;几乎不溶于水。对水和冷碱稳定,能被沸腾的碱金属碳酸盐和苛性碱水解。
生产方法: 由苯甲酸与乙酐反应而得。将苯甲酸、乙酐和糖浆状磷酸一起蒸馏反应,温度不超过120℃,蒸出一定量馏分时,向反应混合物补加乙酐,重复此操作。然后蒸出馏分直至反应物温度达到270℃。将蒸馏剩余物减压分馏,在2.53-2.67kPa压力下,收集210-220℃的馏分即为苯甲酸酐粗品,重结晶得成品。
用途: 有机合成中间体。用于制药、染料、防腐剂、苯酰化剂、软化剂。也可用于水分析。

应用
Benzoic anhydride is used as a benzoylating agent in the manufacture of pharmaceuticals, dyes and intermediates. It serves as an arylation agent in the Heck reaction. It is also used to get benzoic acid through dehydration. Further, it is used to prepare furan-2-yl-phenyl-methanone, which is similar to Friedel-Crafts acylation reaction. In addition to this, it is used for the synthesis of carboxylic esters and lactones.

备注
Moisture sensitive. Incompatible with strong acids, strong oxidizing agents and strong bases.
