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.
