摘要: A process for the management of by-product tetranitromethane (TNM) which avoids the hazards of the prior art isolation or extraction procedures. A selected in-plant liquid or vapor stream, or a reactor off-gas stream from nitration or nitric acid oxidation plant, which contains TNM, is heated to effectively pyrolyze the TNM without undue losses of nitric acid values.

摘要: Process for the mononitration of a nitratable organic compound, such as benzene, with a mixed acid in which one of the reactants is delivered into a body of the other reactant in the form of ultra-fine droplets through an atomizing nozzle or similar orifice. The process is economic to construct and operate, is safe and simple to control and leads to a low cost, substantially pure product.
