氯乙烯(简称VC)是生产聚氯乙烯(简称PVC)的主要原料,它与人民的生产生活密切相关。早在1833年和1838年,法国人Regnault就合成了氯乙烯和聚氯乙烯。1928年美国首先投产,以后英、法国生产,日本是在1949年后。我国自1958年投产以来,工厂和产量不断增加,工厂几十个,大部省市均有生产,速度发展很快。四十多年来,聚氯乙烯塑料产量年年增加,1972年世界PVC产量739万吨,1976年报导,世界聚氯乙烯产量约为每年1,000万吨。
Vinyl chloride (VC) is the main raw material for the production of polyvinyl chloride (PVC), which is closely related to people’s production and life. As early as 1833 and 1838, French Regnault synthesized vinyl chloride and polyvinyl chloride. The United States first put into production in 1928, after the British, French production, Japan is after 1949. Since our country put into operation in 1958, the factory and output have been increasing continuously. There are dozens of factories and most provinces and cities have their own production and the speed has been developing rapidly. Over the past 40 years, PVC plastic production has been increasing year by year. In 1972, the world’s PVC production reached 7.39 million tons. In 1976, it reported that the world’s polyvinyl chloride production was about 10 million tons per year.
