Bromocyclohexane was synthesized from potassium bromide and cyclohexanol in the prensence of concentrated sulfuric acid in water.

以溴化钾和环己醇为原料，在浓硫酸存在条件下，以水为溶剂合成溴代环己烷。

The additional activity of the mechanical mixture can be ascribed to the acid sites on dealuminated Y zeolite, where the activated hydrogen spilt over from the neighboring Pt sites could hydrogenate the adsorbed benzene with the formation of cyclohexane and methylcycloheptane.

发现虽然Y沸石本身没有加氢活性，但它的加入可以显著提高Pt/Al2O3的活性，因为在Pt中心上得到活化的氢可以快速溢流到邻近的沸石颗粒表面的酸中心上，并和吸附在其上的苯发生加氢反应生成环己烷和甲基环戊烷。

Methods Less toxic solvents such as cyclohexane, n-hexane, petroleum ether and chloroform were compared with benzene and toluene.

用毒性较小的溶剂环己烷、正己烷、石油醚和三氯甲烷等取代苯或甲苯。

The response to single compound: To both females and males, the compounds that elicit larger responses of adults are benzaldehyde, benzene acetaldehyde, hexanol,β-phenyl ethyl alcohol, benzyl alcohol, cyclohexanol and eugenol. Phytol, 2-methyl-cyclohexanone and β-caryophyllene reveal to have weaker activity.

对单一化合物的反应：两种昆虫，不论是雌蛾还是雄蛾，能引起较强EAG反应的化合物均为苯甲醛、苯乙醛、正己醇、β-苯乙醇、苯甲醇、环己醇和丁香酚，植醇、2-甲基环己烷和β-石竹烯仅能引起微弱的EAG反应。

New progress on the catalytic epoxidation of cyclohexene was reviewed.

综述了环己烯催化氧化法合成环氧环己烷的最新研究进展。

Under the optimized conditions the conversion of cyclohexene and the selectivity of epoxycyclohexane could reach up to 91.4% and 86.3%, respectively.

在此条件下环己烯的转化率可达91.4%，环氧环己烷的选择性达86.3%。

Extraction rate of artemisinin increased obviously with the decrease of dielectric constant of the mixed trichloromethane and dichloromethane, which was opposite to the results of mixed solvent of hexane and cyclohexane.

用正己烷、环己烷以及它们的混合溶剂作溶剂时，青蒿素的提取率随着溶剂的介电常数的增大而增大，而用二氯甲烷、三氯甲烷以及它们的混合溶剂作溶剂时，青蒿素的提取率随溶剂的介电常数的增大而减小。

A kind of non-equilibrium plasma engendered by silent discharge was utilized to dispose polluted air containing volatile hydrocarbons (hexane,cyclohexane,benzene and toluene) vapor.

采用无声放电产生的非平衡态等离子体，对含有易挥发性有机化合物正己烷、环己烷、苯和甲苯4种典型的烃类废气的空气进行了处理。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.
