n. [有化] 丁烯
1.Propylene and butylene yields increase with low hydrogen transfer reaction.
氢转移反应越低，丙烯及丁烯等烯烃选择性越高。
2.Its main components include propane, butane and butylene.
主要成份是丙烷、丁烷、丁烯等。
3.They mainly includes the utilization of ethene in dry gas and of propene and butylene in liquified petroleum gas.
重点包括干气中乙烯的利用、液化气中丙烯和碳四的利用。
4.The solvent effect of 1-butylene epoxidation was investigated over titanium silicate TS-1 using hydrogen peroxide as oxidant.
研究了用双氧水为氧化剂，钛硅分子筛ts - 1催化1 -丁烯环氧化反应的溶剂效应。
5.Its main components include propane butane and butylene.
主要成份是丙烷、丁烷、丁烯等。
6.These systems can not only dimerize ethylene but also simultaneously copolymerize ethylene with the in-situ formed dimer, 1-butylene, to directly produce LLDPE.
这些催化体系能二聚乙烯，并同时使生成的1 -丁烯与乙烯就地共聚，可以直接合成线型低密度聚乙烯。
