Abstract

Isopropyl nitrate is prepared by the continuous distillation of a mixture of easily volatile products from a liquid reaction mixture which is at a temperature not below the boiling point of the azeotropic mixture of isopropyl nitrate and water and is formed from nitric acid and isopropyl alcohol and into which separate streams of nitric acid and isopropyl alcohol are introduced and in which a urea concentration sufficient to destroy nitrous acid is maintained, at least the isopropyl alcohol being introduced as a vapour below the surface of the liquid reaction mixture. At atmospheric pressure the reaction mixture should be at a temperature of not less than 80.5 DEG C. and preferably above 100 DEG C. The isopropyl alcohol vapour is preferably slightly superheated and preferably consists of an azeotropic mixture of isopropyl alcohol with water, such as that produced by boiling aqueous isopropyl alcohol of higher water content than the azeotropic mixture. The nitric acid concentration of the reaction mixture, including that combined with urea, is preferably from 35-60 per cent by weight, and that of urea is preferably maintained from start to finish at not less than 3 per cent by weight. The desired ammonium nitrate concentration in the reaction mixture is maintained by running a proportion of reaction mixture continuously to waste. Specifications 379,312, 540,050 and 696,489 are referred to.
