摘要
The invention concerns the manufacture of nitromethane by nitration of methane in a homogeneous gaseous phase, the nitrating agent being nitric acid, nitrogen peroxide or mixtures thereof. According to the disclosed process, the molar ratio methane/nitrating agent is between 0.1 and 5; the reaction contact time between 0.1 and 120 seconds; the reaction pressure between 1 and 35 bars; the temperature between 270 DEG and 600 DEG C. The nitration is carried out in the presence of an active agent of the halogen or derivative type introduced in a molar ratio at the most equal to 3. An installation is disclosed for industrially manufacturing nitromethane.
