ABSTRACT:
An invention is a chemical process for complete destruction and safe disposition of hazardous organic chemicals carbonaceous chemicals. The invention also comprises the process for production of an inert polymer formed essentially of Carbon and Sulfur, and also comprises the new inert polymer, itself and articles made of the new polymer. This new polymer has many of the properties of refractory materials and is an inert non-inflammable cross-linked polymer that is relatively insoluble in all generally known solvents. In the process of the invention, a carbonaceous chemical and Sulfur is heated, in an atmosphere of Nitrogen at 500.degree. to 1500.degree. C. Waste gases including sulfur and sulfides are condensed, scrubbed and the sulfur recycled. The solids residue when analyzed by a mass spectrometer contains less than one (1) part per million (1 ppm) of unreacted organic chemical.
