Description
技术领域
本发明属于乙烯齐聚反应技术领域,具体涉及一种降冰片烯PCNP配体、其制备方法及其应用。
背景技术
线型α-烯烃是重要的化工原料,可用作聚烯烃共聚单体、PVC增塑剂、表面活性剂、润滑油添加剂等众多领域。其中共聚单体的用量占α-烯烃消耗量的一半以上,以1-辛烯和1-己烯的聚烯烃产品具有良好的力学性能和优异的加工性能,在工业生产中具有大量的需求。
而选择性齐聚工艺1-辛烯和1-己烯的选择性占总产物的90%以上,选择性好,转化率高,适合工业化生产。目前影响乙烯齐聚的主要原因是烷基铝助催化剂的高成本,烷基铝生产工艺只掌握在全球几家公司中,且其产能有限,因此烷基铝助催化剂一直保持较高价格。
另一问题是聚合物问题一直没能妥善解决。选择性齐聚工业化面临的主要问题之一就是副产聚合物挂壁挂釜引起的堵塞问题。反应釜一旦堵塞,势必影响连续反应,进行停车清理,影响产产品质量和装置的经济性,更甚至会引起管线憋压而引发更大的装置风险。
发明内容
