采用平推流管式反应器,通过对四个相同规格反应器的串、并联组合,形成两种串并联反应器系统,并用于制备苯乙烯-丙烯腈塑料(SAN)。分别讨论了四釜串联和两组两釜串联的并联组合形式下,温度、链转移剂浓度等因素对物料固含量、冲击强度、分子量及其分布的影响。结果表明,四个平推流反应器的串联组合,可形成四釜串联结构的聚合系统,通过每个聚合反应釜的聚合条件控制,可以实现SAN的聚合过程,SAN样品中丙烯腈含量在24%~28%之间。通过两个平推流反应器串联,并部分物流循环的方式,可以实现两组两串联循环反应器的并联组合,在保持四反应器的基础上,使反应体系生产能力倍增。
採用平推流管式反應器,通過對四箇相同規格反應器的串、併聯組閤,形成兩種串併聯反應器繫統,併用于製備苯乙烯-丙烯腈塑料(SAN)。分彆討論瞭四釜串聯和兩組兩釜串聯的併聯組閤形式下,溫度、鏈轉移劑濃度等因素對物料固含量、遲擊彊度、分子量及其分佈的影響。結果錶明,四箇平推流反應器的串聯組閤,可形成四釜串聯結構的聚閤繫統,通過每箇聚閤反應釜的聚閤條件控製,可以實現SAN的聚閤過程,SAN樣品中丙烯腈含量在24%~28%之間。通過兩箇平推流反應器串聯,併部分物流循環的方式,可以實現兩組兩串聯循環反應器的併聯組閤,在保持四反應器的基礎上,使反應體繫生產能力倍增。

Using plug flow tubular reactors,through series and parallel combination of four same specification reactors,two series and parallel reactor systems were formed,and were used to prepare styrene acrylonitrile plastic (SAN). While four reactors in series and two parallel combination of two reactor in series,the influence of factors such as temperature,chain transfer agent concentration on solid content,impact strength,molecular weight and its distribution was discussed separately. The results show that the series combination of four plug flow reactor can form polymerization system of four reactors in series,through the control of polymerization conditions of each reactors,the polymerization process of SAN can be realized,acrylonitrile content in SAN samples is adjusted between 24%~28%. Through the two plug flow reactor in series and part of the logistics cyclic manner,two parallel combination group of two reactors in series is realised,which doubled production capacity of the reaction system while keeping four reactors.
