Abstract
PURPOSE: To obtain a hydrocarbon substance as a raw material for carbon black, particularly suitable for reinforcing rubber, by distilling road tar, treating the resultant bottom fraction with a solvent, and distilling the treated fraction.
CONSTITUTION: Road tar (or a coal or petroleum heavy hydrocarbon substances having the component composition similar to that of the road tar) is distilled and separated into the top fraction having a standard boiling point up to 400°C and the first bottom fraction, which is then mixed with a solvent consisting of an aliphatic hydrocarbon substance and/or alicyclic hydrocarbon substance having a distillate temperature of 65W290°C of 95vol.% at a volume ratio between the first bottom fraction and the solvent of 1:(1W10). The resultant mixture is then allowed to stand and separated into layers. The resultant upper layer is then distilled to distill the solvent from the top of the column, and the resultant second fraction is mixed with the top fraction to afford the aimed substance.
