化工专业英语求翻译
Physical Properties. — Alkenes are known also as ethylenic hydrocarbons and as olefins. The term olefin, meaning oil-forming, was applied by early chemists because the gaseous members of the series combine with chlorine and bromine to form oily addition products.
Alkenes are hardly distinguishable from the corresponding saturated hydrocarbons. The boiling points are no more than a few degrees below those of alkanes of slightly higher molecular weight, and the densities are a few percent higher; in the first few members of the two series there is even a marked correspondence in the melting points. Cycloalkanes differ more from alkanes than alkenes do, and hence ring formation influences physical properties more than introduction of an ethylene linkage. The heat of combustion of 1-hexene is practically the same as that of n-hexane on either a weight or volume basis

物理性质。 - 烯烃也被称为烯碳氢化合物和烯烃。长期烯烃，这意味着石油的形成，是适用于早期的化学家，因为该系列的气态氯和溴的结合，形成油性此外产品。
从相应的饱和烃，烯烃是很难区分。沸点不超过数度更低于略高分子量的烷烃，密度高几个百分点;在这两个系列的前几的成员甚至有显着书信在熔化点。环烷烃不同烷烃比烯烃做更多，因此环的形成，影响物理性质，化学性质，多引进乙烯联动。 1 - 己烯的燃烧热，实际上是正己烷相同的重量或体积的基础上
