Thermal stability of heterocyclic sulfur compounds

  • Published:
Chemistry and Technology of Fuels and Oils Aims and scope

Summary

  1. 1.

    The thermal stability of heterocyclic sulfur compounds has been studied by means of derivatography and isothermal gravimetry. It has been shown that the temperature for initial rupture of the five-membered ring decreases upon going from 3-phenyl-5-ethyl-4-thioxo-2-thiazolidone to 3-phenyl-4-thioxo-2-thiazolidone. The weight losses upon heating (isothermal conditions) increase in this same order.

  2. 2.

    It has been established that the addition of metals catalyzes the breakdown process for 4-thioxo-2-thiazolidones.

  3. 3.

    It has been shown that splitting of the thiazolidone ring takes place at the sulfur-containing junction, with the formation of dimerized nitrogen-containing compounds.
