| 中文摘要: |
| 介绍我国对位芳纶主要原料对苯二甲酰氯的技术进展。对位芳纶生产对原料对苯二甲酰氯的纯度要求很高，虽然近年来对苯二甲酰氯生产工艺和装置设备研究有一定进展，但目前国内对苯二甲酰氯工业生产方法主要是氯化亚砜法，且基本上采用间歇法，对苯二甲酰氯质量仍不稳定，设备自动化程度较低，三废量大。今后对苯二甲酰氯产业仍应加快技术开发，提高生产自动化程度和产品质量，探索三废处理新方法，降低生产成本。受对位芳纶生产能力所限，对苯二甲酰氯需求量在短期内不会快速增长。 |
| 英文摘要: |
| The technology progress of paraphthaloyl chloride in China is introduced.The para-aramid fiber production has high requirements for the purity of paraphthaloyl chloride.At present，sulfoxide chloride method is the main method in industrial production of paraphthaloyl chloride，and basically by batch process. Some progress has been made in the research of the production process and equipment of paraphthaloyl chloride in recent years，but the quality of paraphthaloyl chloridet is not stable，the automation degree of the equipment is low，and the waste amount is large.In the future，main work is to accelerate the development of technology，improve production automation and product quality，explore new methods of waste treatment，and reduce production cost.Limited by the production capacity of para-aramid fiber，the demand for paraphthaloyl chloride will not increase rapidly in the short term. |
