1、1,Chapter 9 Oxidation-Reduction Reactions and their Industrial Possibilities,9.1 General Introduction of oxidation,1. The reaction types,+O in organic compounds,both -H and +O in organic compounds,organic compounds oxidation and decomposition,organic compounds ammoniac-oxidized,Epoxy-ethane,Cyano-co
2、mpound,2,2. can be made by the oxidation reactions,ROH,Epoxy-compound,Cyano-compound,3,3. The general features of the oxidation reactions,1)The oxidizing agents,The gas phase oxygen O2 cheaper, without the instrument damage, but lower oxidizing ability need catalytic.,Oxygen atom O generated from th
3、e chemical oxidizing agents, high oxidizing-abilities, high selection, mild reaction conditions, but high cost.,4,2) Strong heat releasing reactions,3) Unconverted reaction,4) Multi-reaction ways and with by-reactions,In order to obtained the target oxidized compound, the suitable way must be select
4、ed,5,The air is flowed into the organic compound in liquid phase under the action of catalytic, then the compound is oxidized, this kind of reaction has been called the air liquid phase oxidation reaction,9.2 Air liquid phase oxidation reactions,Definition for the reaction,requirement,A: special rea
