Abstract

The residue from the distillation of benzol which has been purified with sulphuric acid is treated to yield a resin by subjecting it to cracking distillation either alone or mixed with the resinous product separated from the acid drawn off; the resin in the case of joint distillation is soluble in benzol and may be used as a substitute for coumarone resin.ALSO:In purifying a crude benzol containing solvent naphtha and benzols of lower boiling point with sulphuric acid, acid of 80-93 per cent concentration is used at temperatures between 10 and 45 DEG C. with the object of avoiding oxidation and sulphonation. The crude benzol may be given an increased content of resin-forming substances by adding solvent naphtha, heavy benzol, or tar oils, or by incomplete dephlegmation in distilling the benzol from the saturated washing oil. Resinous materials are obtained as a residue on distilling the purified benzol, and may also be separated from the acid drawn off, the resinous materials yielding motor fuel, oil and resin when subjected, together or separately, to cracking distillation. The resin obtained by joint distillation is soluble in benzol and may be used as a substitute for coumarone resin.
