摘要
用实验方法测定了硫脲在室温和加热条件下稳定性同溶液pH位的相对关系,根据硫脲分解产物和硫脲分子结构讨论了硫脲的分解机理,提出了硫化氢法生产硫脲新工艺流程,在实验室试验获得成功.
The relation between the stability of thiourca and pH values of its solution at room temperature or heating conditions was researched by experiment methods. The decomposition mechanism of thiour a was discussed according to its decomposition products and its molecular structure. The new process flow proparing thiourca by H_2S method was studied and was sucessful in laboratory.
