氯化亚砜是一种重要的化工产品和化工原料,在染料、医药、农药等传统行业中具有广泛的用途。2015年全球氯化亚砜生产能力97.6万吨/年,较上年增长21.1%。氯化亚砜生产企业主要分布在中国、德国、美国、印度和瑞士等国家。截至2016年底,国内氯化亚砜产能达到42万吨/年,同比增长20%,产量为26万吨,同比增长22%。近几年,国内氯化亚砜主要是自产自销,没有出口,只有少量进口。目前,国内氯化亚砜产能严重过剩,未来几年建设步伐将会减缓,一些期模较小、竞争力差的公司将被淘汰。
Thionyl chloride is an important chemical product and chemical raw material and has a wide range of uses in traditional industries such as dyes, pharmaceuticals and pesticides. In 2015, the global thionyl chloride production capacity was 976,000 tons / year, up 21.1% over the previous year. Thionyl chloride production enterprises are mainly distributed in China, Germany, the United States, India and Switzerland and other countries. As of the end of 2016, the domestic production capacity of thionyl chloride reached 420,000 tons / year, an increase of 20% over the same period of the previous year with a production volume of 260,000 tons, an increase of 22% over the same period of last year. In recent years, domestic thionyl chloride is mainly produced for sale, there is no export, only a small amount of imports. At present, the domestic excess capacity of thionyl chloride, the pace of construction in the next few years will slow down, some of the smaller period, the less competitive companies will be eliminated.
