Preparation: 1. Obtained by nitration of propane. The silica is introduced into the preheater at-430 ℃ and then the glass is put into the preheater at 450 ℃. 75% nitric acid can be injected into propane gas in several places of the reactor. The reaction temperature is adjusted to 390-440 ℃, the pressure is 0.69-0.86mpa, and the mole ratio of propane to nitric acid is 5:1. The gas from the reactor is cooled by condenser, and the nitropropane and dilute nitric acid condense. Propane and gaseous oxides are recovered by the recovery tower, and propane is recycled. The products are nitromethane 10% - 30%, nitroethane 20% - 25%, 1-nitropropane 25%, 2-nitropropane 40%. The product can also be obtained by nitration of propylene. 2. Nitropropane can also be obtained by nitration of unsaturated hydrocarbons such as propylene in gas or liquid phase or in liquid phase of saturated hydrocarbon. 1.
