摘要:在中国,氯化铵主要用作氫肥,附加值很低,严重制约了联碱企业的经济效益,而且存在氯资源浪费、
长期施用易造成土壤板结等问题。文章分析了中国在氩化铵应用中的不合理状况,介绍了国内外氯化铵应用
エ艺研究现状,对以氯化铵为原料制取氨气、氯化氢、氯气、氯代烃等其他化エ产品的エ艺进行了分析比較,
表明以氟化铵为原料制备氨气、氣化氢或氟气的工艺虽然在特定领域有着一定的应用,但并不适合从整体上
解决中国数量虎大的氩化铵出路问题。提出了氧化铵参与乙炔氩氟化和乙烯氧氟化合成氯乙浠的エ艺路线,
能够充分利用氯化铵中的氣资源并产出高附加值的氯乙烯产品,对解决中国氟化铵不合理利用现状具有重要
的参考和指导意义

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 provide
an important reference and guidance on solving the irrational use of ammonium chloride in our
country
Key words ammonium chloride; ammonia; hydrogen chloride; chlorinated hydrocarbons
