补充资料:过磷酸
分子式:
CAS号:
性质:在正磷酸(H3PO4)和焦磷酸(H4P2O7)之间存在一种低共熔物,共组成为含75.4%P2O5,相当于105%H3PO4,工业上称为过磷酸。它具有P2O5含量高,腐蚀性比正磷酸小,冰点低,在室温下呈液态,有显著的过冷特性,对金属杂质离子具有极强的螯合能力,在贮存和长途运输中不会产生淤渣。商品过磷酸有含105%,110%和115%H3PO4等三种规格。实际上他们是正磷酸、焦磷酸、三聚磷酸、四聚磷酸以及少量高聚磷酸的混合物。其生产方法有热法和湿法两种。热法系燃烧元素磷再经氧化、水化直接制得。湿法是将湿法磷酸浓缩、深度脱水后制得。可用来生产营养组分高的液体肥料或悬浮肥料。也可用作有机化学的催化剂和脱水剂。
