Embodiment 1
[0018] The industrialized reaction method of trimethylolethane trinitrate, it may further comprise the steps:
[0019] 1) Pump the working acid into the reaction kettle to fill the reaction kettle with working acid; ensure that the mass percentage of each component in the working acid meets the following indicators: HNO 3 49.5%, H 2 SO 4 49.5%, H 2 O0.5%, HNO 2 0.5%; the sum of the total mass percentage is 100%.
[0020] 2) Melt TME, transport it into the nitrifier in the form of slurry, and pump in the working acid while pumping the TME slurry; the nitrification temperature in the nitrifier of the reactor is 12.5°C; The nitrification coefficient is 3.8. The weight ratio of TME slurry to working acid is 1:3.8.
[0021] 3) The reaction takes place under the strong stirring of the stirring device, and the rotating speed of the stirring device is 700Rad / min. The generated heat is taken away by the cooling coil in the reaction kettle, and the generated products trimethylole...
