ABSTRACT:
A method of making either a softener for rubber mixtures or a furnace fuel oil comprises the steps of heating a hydrocarbonaceous solvent and introducing thereinto waste from vulcanized or nonvulcanized rubbers under intensive stirring. Then the waste is thermally decomposed at a pressure of 5.multidot.10.sup.2 to 25.10.sup.5 n/m.sup.2, the hydrocarbonaceous solvent continuously circulating through the reaction mixture. The end product is separated from the formed suspension by distillation at a temperature of 200.degree. to 560.degree. C. and at a pressure of 10 to 2.multidot.10.sup.5 n/m.sup.2 in the presence of an inert gaseous agent.
