| Abstract：Using a mixture of nitric and sulfuric acids as nitrating agent, isooctanol was nitrated in a microchannel reactor to give isooctyl nitrate. The effects of reaction temperature, ratio of mixed acid, concentration of nitric acid, residence time and ratio of reactants on the yield of the product were investigated. The optimum conditions for the synthesis of isooctyl nitrate in microchannel reactor were tested. The yield of product reached 97.8%, the purity reached 99.5%. This continuous synthesis of isooctyl nitrate in microchannel reactor had the advantages of simple operation, short reaction time, high conversion rate, high yield, safe and reliable, and had the prospect for industrial application. |
