PROCEDE DE PREPARATION DES NITROPARAFFINES PAR NITRATION EN PHASE GAZEUSE

摘要

Nitroparaffins are made by nitration in the gaseous phase under pressure, possibly in the presence of a gas containing oxygen. The reagent to be nitrated is a mixture containing a substantial amount of propane, the reaction temperature and pressure, the contact time and the quantitative ratios between the nitrating agent, the mixture to be nitrated and the oxygenated gas being selected so that the nitration reaction is conducted in a homogeneous gaseous phase. The process makes it possible to obtain a percentage of different nitroparaffins in response to industrial demand and further to use the cheapest raw materials at a given moment.
