Method of making either a softener for rubber mixtures or a furnace fuel oil

摘要

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 5x102 to 25.105n/m2, 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 DEG to 560 DEG C. and at a pressure of 10 to 2x105 n/m2 in the presence of an inert gaseous agent.
