A reactor for nitration of saturated hydrocarbons having less than five con atoms, alone or in admixture, in the gaseous phase under pressure is made up of a reaction enclosure, in which a tube or pipe bank is in contact with a heated fluid of high heat-exchange capacity. The inside perimeter of the tubes does not exceed 800 mm, and if circular not in excess of 250 mm, and the ratio of the surface of the tube bank, in contact with the reaction medium, to the volume of the reaction enclosure is 1:1 to 3:1. The reactor apparatus further includes a mechanical means to uniformly distribute the delivery of reaction medium gases to the various tubes of the bank so that the load difference between the most loaded tube and that of the least loaded tube is equal to 10% at the most. The reactor also includes a tube bank injector which feeds the tube bank to assure homogeneous mixing of all the reaction fluids in the tube bank.
