醋酸铅,亦称乙酸铅,俗称铅糖 [1] 。化学式(CH3COO)2Pb,Mr=325,通常指的是三水合物,也有十水合物和无水物 [2] 。
三水合醋酸铅为无色结晶、白色颗粒或粉末,略带乙酸气味,具有风化性,有毒。熔点60-62℃,沸点280℃(常压),15℃时溶解度为45.6,100℃为200。
用于制备各种铅盐、抗污涂料、水质防护剂、颜料填充剂、涂料干燥剂、纤维染色剂以及重金属氰化过程的溶剂。
三水醋酸铅,白色单斜晶体,密度2.55g·cm-3(25℃)。熔点75℃(急热)。可燃。略带乙酸气味。具有风化性。折射率1.567。是共价化合物,且为弱电解质。易溶于水,溶解度55.04g/100g水。也溶于丙三醇,不溶于乙。75℃时失水成无水醋酸铅。[2] [4]
十水醋酸铅,白色正交晶体,密度1.69g·cm-3(25℃)。常温下容易风化失水。弱电解质。易溶于水,溶于丙三醇,不溶于乙。[2]
无水醋酸铅,白色粉末,密度3.75g·cm-3(20℃)。熔点280℃。弱电解质。易溶于水,溶解度44.3g/100g水。不溶于乙。
