中译英. 1, 生锈的化学过程并不十分清楚, 但已确认铁锈是氧和湿气作用生成的水合氧化铁, 并且, 由于微量的二氧化碳的存在生锈的速度将显著加快. 2, 饱和烃尽管可以发生象卤代这样的化学反应, 但是总的化学反应活性相对较低, 相 比之下,不饱和烃易发生加成反应, 芳香族化合物则往往容易发生取代反应. 3, 气体溶质的分压与其在溶液中的溶解度之间的关系可用亨利定律来描述, 即气体 溶质的分压与其在溶液中的溶解度成正比. 4, 色谱法能将不同的组分分离是基于被分离物质的溶液中各组分与色谱中固定相和 流动相之间的亲合力存在差异. 5. 对于液体有机物的分离和提纯来说, 应用最为广泛的方法是蒸馏, 其中包括常压蒸 馏, 减压蒸馏, 水蒸汽蒸馏和分馏. |

| 1, the rusting chemical processes are not clear, but the rust has been confirmed is the role of oxygen and moisture generated by iron oxide hydrate, and that the small amount of carbon dioxide due to the existence of the rust will significantly speed up the pace. 2, despite the saturated hydrocarbons can be Halides such as occurred in a chemical reaction, but the overall chemical reaction activity is relatively low, compared with unsaturated hydrocarbon prone addition reaction, aromatic compounds are often vulnerable to substitution. |

| 3, gas pressure of the solute and its solubility in solution of the relationship between Henry's Law can be used to describe that the gas pressure of the solute and its solubility in solution is directly proportional. 4, law chromatography to separate components separation Is based on the material to be separated from the solution of each component with the stationary phase in chromatography and liquid-phase affinity between different. 5. Liquids for the separation and purification of organic compounds, the most widely used method is distillation, including Atmospheric distillation, vacuum distillation, steam distillation and fractionation. |
