In part 3 , the in - situ copolymerization of ethylene was investigated by the combinations of the cobalt - based catalyst and the metallocene to prepare short - branched polyethylene . the major oligomers catalyzed by the cobalt - based catalyst 5 , 6 and 7 werel - butene , and the minor were 1 - hexene . the comonomer effects were also observed 在雙亞胺基吡啶鈷配合物與茂金屬復配催化乙烯原位共聚制備短支鏈支化聚乙烯中,合成了3種雙亞胺基吡啶鈷配合物,研究了反應條件對其催化乙烯齊聚活性和所得產物碳數分布的影響。

From four parts , the paper expounds upon the feature of the new process and the plant arrangement , and discussed emphatically the procedure of manufacturing 1 - hexene from 2 - butene isomerazation reaction & 1 - butene automethathesis and hexene isomerazation reaction 摘要論述了天津石化乙烯回收新技術擴大中試裝置的工藝特點、新工藝的主要流程和設備布置的設計方法。

1 - butene for industrial use - determination of trace methanol and methyl tert - butyl ether - gas chromatographic method 工業用1 -丁烯中微量甲醇和甲基叔丁基醚的測定氣相色譜法

1 - butene for industrial use - determination of purity and hydrocarbon impurities - gas chromatographic method 工業用1 -丁烯純度及烴類雜質的測定氣相色譜法

1 - butene for industrial use - determination of trace propadiene adn propyne - gas chromatographic method 工業用1 -丁烯中微量丙二烯及丙炔的測定氣相色譜法

Duplication of bands in this region is also shown by trifluoropropyne and perfluoro2 - butene 三氟丙炔和全氟丁烯- 2在這個區域也出現雙重譜帶。
