demand and further to use the cheapest raw materials at a given moment application_number US 2559479 A description the process can be conducted under different reaction pressures from atmospheric to 100 bars preferably between 10 and 30 bars the reaction contact time can go from 0 01 to 20 seconds particularly 1 to 10 seconds preferably on the order of 5 to 8 seconds it has been observed with nitric acid and nitrogen peroxide and other nitrating agents as well that the reaction temperature variation makes it possible under certain conditions to change the spectrum of nitroparaffins with a concomitant variation in the specific consumptions of alkane and nitrating agent the temperature zone to be taken into consideration in using nitrogen peroxide is 280 u00b0 to 350 u00b0 c with nitric acid it can be higher on the order of 300 u00b0 to 500 u00b0 c in the case of nitration of propane with nitrogen peroxide in the presence of air an increase of reaction temperature from 300 u00b0 to 360 u00b0 c leads to a variation in the distribution of the nitroparaffins produced corresponding to an increase in the percentage of nitromethane in the condensed effluent and a slight increase in the amount of nitroethane and 1 nitropropane with a simultaneous rapid and considerable drop in the quantity of 2 nitropropane although raising the temperature involves an increase in specific consumption of propane and nitrating agent there are high temperature operating points for which the profitability of the nitration is maximal given that 2 nitropropane is less valuable than the other three nitroalkanes it can be assumed that some of the.
