Abstract: Ammonium chloride is mainly used as a nitrogen fertilizer in China，low value-added，which has seriously compromised the economic benefits of alkali enterprises. There are many problems associated，such as the waste of chlorine resources，soil compaction easily led by long-term application and other issues. This paper analyzes the unreasonable application situation of ammonium chloride application in our country，and introduces the application processes at home and abroad. Processes of using ammonium chloride as raw material for preparing ammonia，hydrogen chloride，chlorine，chlorinated hydrocarbons and other chemical products are compared. It shows that although there is a certain application processes using ammonium chloride as raw material for preparing hydrogen chloride or chlorine in specific areas，they are not able to solve all problems in a huge number of ammonium chloride enterprises in our country. At the end of this article，we propose the vinyl chloride synthesis process route with ammonium chloride participation in the hydrochlorination of acetylene and the oxychlorination of ethylene，which can fully transform the chlorine resources of ammonium chloride into high value-added output of vinyl chloride. It provides an important reference and guidance on solving the irrational use of ammonium chloride in our country.
