磷酸
Phosphate standard concentrate
Cas     7664-38-2      MDL:     --MFCD00011340
Beilstein 1921286        EINECS:        --231-633-2
分子式    H3O4PH3PO4
分子量    98.00
别名       正磷酸,一缩原磷酸,缩原磷酸,乙烯利水剂
Phosphoric acid solution

Orthophosphoric acid
分子结构式   
性状       无色、无臭、粘稠液体,溶于水及醇。纯品磷酸为无色斜方晶体,富潮解性。溶于水和乙醇。其酸性较硫酸、盐酸和硝酸等强酸为弱,但较醋酸、硼酸等弱酸为强。能刺激皮肤引起发炎及破坏肌体组织。磷酸溶于水并放热,经高温加热便失水成焦磷酸和偏磷酸,长时间受冷即生成结晶,有腐蚀性,易吸湿。
