总结了我国氯乙烷的需求现状、生产企业及产能，分析了我国氯乙烷供需状况和氯乙烷生产企业间的竞争状况。我国氯乙烷需求量约5.6万t/a，其中在染料中间体合成上的需求量占总需求量的48%，居第一位；氯乙烷总产能达11万t/a，其中合成氯乙烷产能10万t/a，合成氯乙烷企业不宜再扩大生产规模。

China's market demand status of chloroethane is summarized from the synthesis of tetraethyl lead,ethyl cellulose,pesticides,spices,dye intermediates,aluminum ethyl,ethyl chlorosilane and the use of organic solvents.The main sources and corresponding enterprises of recovering chloroethane,as well as the production of synthetic chloroethane and its capacity in China are introduced.The supply and demand situation of chloroethane with the competition among chloroethane producers are analyzed.China consumes around 58 thousand tons of chloroethane a year,with main applications in the synthesis of ethyl organic compounds,such as dyes intermediates and spices.The dyes intermediate sector is the biggest consumer,accounting for 48% of the total demand.China's total capacity of chloroethane is 110 thousand tons per year,of which the synthesized chloroethane is about 100 thousand tons per year.China's production capacity is much more than domestic demand.Existing synthetic chloroethane enterprises is not advisable to expand capacity.
