氯油制氯仿废液综合利用工艺流程研究

Study on Technological Process of Comprehensive Utilization of Waste Liquid Producing Chloroform from chlorine Oil

氯油经氢氧化钠碱解后，除得到主产物氯仿外，其余为含甲酸钠、氯化钠、氢氧化钠等物质的甲酸钠废液。本文研究了甲酸钠废液转变为草酸的工艺流程。

Main product-chloroform is obtained from alkaline hydrolysis of chlorine oil, the rest are waste liquids of sodium formate containing sodium formate,sodium chloride and sodium hydroxide.In this paper,technological process of conversion of waste liquid of sodium formate to oxalic acid is described.
