【摘要】 石油液化气中的烯烃(主要是碳四烯烃)在定向催化剂的作用下,选择叠合成分子量较大的聚合体。它的组成基本是异丁烯二聚体(即碳八烯烃)和三聚体(即碳十二烯烃)的同分异构体。有机化合物的同分异构体的分离和结构鉴定是比较复杂的。采用毛细柱、程序升温气相色谱技术,使异丁烯二聚体和三聚体得到良好分离,并对其中各组分进行鉴定和定量分析。更多还原

【Abstract】 The olefines (mainly C4 olefines)in the liquefied petroleum gas under the action of a selective catalyst were polymerized to form heigher molecular weight diners and trimers. The principal constituents of the product were isomers of diisobutylene and triisobutylene (i. e. C8 olefines and C12 olefines). The process of the separation and i-dentification of the organic compound isomers is relatively complicated. Dimers and trimers of isobutene were completely separated by the technique of temperature programmed gas chromatography on a capillary column. Each constituent is identified and quantitated.更多还原
