摘要
介绍了氯乙烯-醋酸乙烯酯共聚后未转化VAC的回收工艺;比较了减压、常压两种工业化生产回收方案,结果表明,常压回收方案的VAC回收率基本在90%以上,优于减压回收方案。
The recovering process of unconverted VAC after copolymerizing vinyl chloride-vinyl acetate is in- troduced. The industrial rccovery schemes under nomal and negative pressure were compared the results sgiwed that, VAC recovery under nomal pressure, is basically over 90% ,higher than that under negative pressure.
