Title: Safe method for thermal decomposition of nitrogen trichloride

Abstract: Nitrogen trichloride normally explodes when heated to 95.degree. C. However, when a dilute solution of NCl.sub.3 in an inert solvent is heated to a temperature in the range of 105.degree.-140.degree., controlled decomposition to nitrogen and chlorine results. Nitrogen is innocuous and can be vented to the atmosphere. The chlorine is recovered. This method of NCl.sub.3 disposal is uncomplicated and non-polluting and constitutes a distinct improvement over prior art methods. The process of the invention finds utility primarily in destroying nitrogen trichloride formed as a by-product in the manufacture of trichloro isocyanuric acid.
