Regarding oxidation reactions
Thread Content
Dear sea friends, I have a problem and would appreciate your help in thinking about it. If a solvent is used in the oxidation reaction, should the reaction temperature be kept below the flash point of the solvent, reactants, and products? By how much should it be lower than the flash point? The oxidant I am using is air. Please give me some more advice!
Reply 1# wangtiejian: Generally, it is required that the flash point of flammable liquids be 20–30°C higher than the operating temperature, in order to ensure safe use and reduce volatilization losses. The oxidant you are using is air, and the oxidizing power of air is much lower than that of pure oxidizing gases. There are also inert gases such as nitrogen; I think a minimum temperature of 20°C will suffice. Personal opinion, for reference only.
