氯乙烯单体中水分测定方法探讨

Discussion on the method of determining the water content in VCM

采用卡尔菲休测定法对氯乙烯气体中的水分含量进行测定,可以准确指导生产部门及时更换固碱,确保精氯乙烯中水质量分数控制在3×10-4以下。

Karl Fischer measurement method was adopted to determine the water content in VCM.It could direct production department to replace the solid sodium hydroxide in time to ensure the water content in rectified VCM less than 3×10-4.
