VERFAHREN ZUR VERNICHTUNG VON TETRANITROMETHANNEBENPRODUKT.

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 vapour stream, or a reactor off-gas stream from nitration or nitric acid oxidation plant, which contains TNM, is heated to effectively pyrolyse the TNM without undue losses of nitric acid values.
