摘要
苯乙烯焦油是苯乙烯生产厂的工业下脚料,其主要化学成份是苯乙烯的低聚物,聚合度为几十到几百.常温下是一种高度粘稠的物质.目前国内外对其开发利用不多,绝大多数厂家只做燃料,我们课题组于1988年底专门立项研究了该焦油的开发利用问题,我们研究的重要环节是焦油的热裂解,至于裂解液的分离.因它是有机化工分离(分馏)的普遍性问题,本文仅对苯乙烯焦油热裂解过程中的若干问题加以讨论.
Styrene tar is a scrap material in the production of styrene. Its major chemical composition are low polymers of styrene whose degrees of polymerization are from dozens to hundreds. Under ordinary temperature, it is a highly viscous substance. Our research group set a project to study the problem of its development and utilization. The key link of our research is the thermal cracking decomposition of styrene star. Therefore this article only deals with some of the problems in the process of thermal cracking decomposition of styrene star.
