    物化性质:
    无色单斜晶系片装或柱状结晶,有光泽,相对密度1.306,熔点149.6℃,易溶于水、乙醇、液铵、丙酮、砒呤和液体二氧化硫中,溶于水时呈吸热反应,遇铁盐生成血红色的硫氰化铁,与亚铁盐不反应,在日光作用下溶液呈红色,加热至140℃左右时形成硫脲,170℃时分解为氨,易潮解,应密封贮存。
    Physico-chemical property:
    Olorless monoclinic system tablets or columnar crystal, luster, relative density 1.306, melting point is 149.6 , soluble in water, ethanol, liquid ammonia, acetone, arsenic poison and liquid sulfur dioxide, and it is endothermic reaction, while soluble in water in molysite generated blood-red rhodanide iron, do not reaction with ferrous salt, the solution becomes red under the action of the sun , thiourea are formed when heated to 140 , 170 when broken down into ammonia, easy deliquescence, should be sealed storage.

    用途:是制造双氧水的辅助原料,用作染料,有机合成的聚合催化剂,用于农药、抗生素的分离,分析试剂等。
    Application: It’s the auxiliary raw materials manufacturing hydrogen peroxide, used as a dye, polymerization catalysts in organic synthesis, used for the separation of pesticides, antibiotics, analytical reagent, etc.
