    Abstract: Nitroparaffins are made by reacting an alkyl nitrite, having at least 2 carbon atoms, with nitric acid or an oxide of nitrogen higher than nitric oxide in the vapour phase at a temperature of at least 240 DEG C. The reaction proceeds with splitting of the alkyl nitrite molecule to yield a nitroparaffin containing fewer carbon atoms than the starting material. Nitrogen dioxide is specified as a suitable nitrating agent. Examples relate to the preparation of nitromethane, nitroethane, 2-nitropropane, nitrobutane and nitropentane.
