Anilido-imino nickel complex 1 {(C6H3Me2-2,6)N=CH-5-NO2-C6H3N (C6H3Me2-2,6)}NiBr was first synthesized, and its catalytic behavior toward polymerizations of norbornene and ethylene in the presense of methylaluminoxane were investigated in detail. The complex activated with methylaluminoxane exhibited high activities for norbornene polymerization.

The vast majority of these polymers after combustion split into fluorinated alkene, while the fluorinated alkene is that it may cause cancer substances.

指出，这些聚合物燃烧后绝大部份分裂为氟化烯，while的含氟烯烃认为它可能是导致癌症的物质。

This paper mainly studies the effect of pressure, LHSV, temperature and mole ratio of alcohol and alkene on conversion ratio of tertiary amylene.

本文主要考察和研究了反应压力、空速、反应温度、醇烯摩尔比对叔戊烯转化率的影响。

Catalytic effect of ionic liquids to isobutane and butene alkylate reaction was studied,composition of ionic liquids,isobutane and butene mole compares factors to the alkylate reaction influence was reviewed.

研究了离子液体对异丁烷与正丁烯烷基化反应的催化作用，考察了离子液体组成、异丁烷与正丁烯物质的量比等因素对烷基化反应的影响。

During the reaction of alkylation, general contained 0.2%~2.0% butadiene will produce viscous heavy composite materials, which will raise final boiling point of alkylate and decrease octane, what is more, it will react with acid to produce corresponding ester, which will increase the consumption of acid, Therefore, we must remove butadiene by selective hydrogenation, at the same time, it will convert some of 1- butane to 2- butane by isomerization and raise octane of alkylate.

一般含有0.2%~2.0%的丁二烯，其在烷基化反应中，可生成一种分子量很高的粘稠重质迭合物，使烷基化油的干点升高，辛烷值降低，并且它还和酸反应生成相应的酯而加大酸耗量。因此必须经过选择性加氢除掉丁二烯，同时，将部分1-丁烯异构化为2-丁烯，以提高烷基化油的辛烷值。

Silsesquioxanes are a large branch of organic-inorganic silicon-containing compounds. They can be represented as RSiO_(3/2_n, where R can be hydrogen or any alkyl, alkylene, aryl, arylene groups, or organo-functional derivatives of them.
