Abstract

TMTD, diphenylmethane and zic oxide were heated at 120 or 140°C under the atmosphere of nitrogen. Gaseous products and the products of low boiling points were captured and analyzed by a mass spectrometer. Carbon disulfide and thiocarbonyl were identified, and ratio of both gases was measured in the gaseous mixture. Dimethylamine, monomethylamine and carbon disulfide were identified, and ratio of these three compounds in the mixture of low boiling points was measured. Chemical analysis on carbon dioxide, thiocarbonyl, carbon disulfide and other products remained in the reaction system was also carried out. Exchange reaction between a sulfur atom in dithiocarbamategroup and oxygen atom in zinc oxide and further exchange reaction such as<br>_??_<br>must take place and result in the evolution of thiocarbonyl and carbon dioxide beside carbon disulfide accompanied by the evolution of amines.
