Abstract: A process for the continuous production of isopropyl nitrate by the continuous distillation of a mixture of easily volatile products from a boiling reaction mixture 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 effective to destroy nitrous acid is maintained is characterized in that there is passed through said boiling reaction mixture undergoing continuous distillation a stream of gas chemically indifferent to it. The indifferent gas may be, e.g., air, nitrogen, carbon dioxide or steam. The isopropyl alcohol and also the nitric acid introduced into the reaction mixture may contain urea. In an example aqueous isopropyl alcohol and nitric acid, both containing urea, are fed into a reactor containing heated aqueous nitric acid also containing urea whilst air is passed through the reaction mixture. Crude isopropyl nitrate is continuously separated from the aqueous distillate. Isopropyl alcohol may be recovered from the aqueous layer of the condensate by fractional distillation after neutralizing the nitric acid present. Specification 379,312 is referred to.
