| Abstract: | In order to promote the application of micro-chemical technology in the synthesis of nitroglycerin, the process of continuous synthesis of nitroglycerin by micro-reaction system was studied by using glycerin, nitric acid and sulfuric acid as raw materials in a chaotic micro-mixer designed independently. Influence of microchannel size, reactants molar ratio and reaction temperature on nitroglycerin yield in micro-mixer was investigated. The optimum conditions were determined. When the diameter of microchannel is 1.0 mm, the reaction temperature is 19℃, the reaction time is 5 min, and the molar ratio of glycerol to nitric acid is 1.0∶ |
