Abstract:
Method for the purification of nitroketones from crude mixtures containing, in addition to the nitroketone, nitronitrates, nitroalcohols, denitrating agent and nitric acid, wherein the crude mixture is initially treated with ammonia thereby forming and separating the ammonium salt of the nitroketone and ammonium nitrate from the crude mixture, contacting the ammonium nitrate and ammonium salt of the nitroketone with a liquid hydrocarbon at a temperature sufficient to decompose the ammonium salt of the nitroketone to ammonia and said nitroketone, separating ammonia and ammonium nitrate from the hydrocarbon and nitroketone and separating the nitroketone from the hydrocarbon.
Abstract:
