The catalytic efficiencies of a variety of fatty ketones, alicyclic ketones and heterocyclic ketones and the impact factors were reviewed in the paper.

本工作对各种脂肪酮、脂环酮、杂环酮对烯烃环氧化催化能力的大小及其影响因素进行了评述。

Based on the molecular topological theory, a modified group dyeing indexL is introduced. It is used in the study of refractive index of the ketones and ethers. Relationship between the refractive index and molecular structure of 57 ketones and ethers is studied by using quantitative structure-property relationship technique. The reasonable molecular modeling equations are obtained by multiple regression for the prediction of the refractive index of ketones and ethers.

在分子拓扑理论的基础上，提出了一个修正的基团染色指数L，运用定量结构－性质相关技术研究了57种酮类和醚类化合物分子的折射率与分子结构间的定量关系；通过多元回归的方法建立了L与折射率的定量结构－性质相关模型。

Ketones：酮类

在氧化过程中会产生过氧化物(peroxides),此不安定的化合物会继续氧化而产生醛类(aldehydes)、酮类(ketones)以及游离脂肪酸而提高酸价,也会产生不好的油臭味.

Ketones：酮

至于有机气体的渗透力,以卤化碳氢(halogenated hydrocarbons)为最高,碳氢次之,然后是醚(ethers)、酯(esters)酮(ketones)、醛(aldehydes)、酸,最低是酒精假如有磁性液体或水蒸气,而物料又受到拉力功内在应力时,PE有可能会出现环境应力龟裂.
