氯乙烯单体精馏系统改扩建后，基于前三年氯乙烯单体中乙炔含量偏高问题，以精馏原理等理论为指导，通过共况调查和分析，得出结论：氯乙类单体中乙炔含量控制偏高的注要原因是粗氯乙烯纯度偏低，低沸塔工作不正常等等。通过有针对性的逐步整改，使氯乙烯单体中乙炔含量得以控制。

浩瀚色谱（山东）应用技术开发有限公司用色谱法,从气相色谱工艺条件人手进行改进.设计了氯乙烯单体中低沸物乙炔含量的测定方法,取得了较好的效果.

After the renovation and expansion of the vinyl chloride monomer rectification system, based on the problem of high acetylene content in the vinyl chloride monomer in the previous three years, guided by the theory of distillation principles, through the investigation and analysis of the common conditions, it is concluded: The main reason for the high acetylene content control in the body is that the purity of crude vinyl chloride is low, the low-boiling tower is not working properly, and so on. Through targeted and gradual rectification, the acetylene content in vinyl chloride monomer can be controlled.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses chromatography to improve the process conditions of gas chromatography. A method for determining the content of acetylene, a low-boiling substance in vinyl chloride monomer, has been designed, and good results have been achieved.
