Title: Improvements in or relating to the treatment of crude benzol
IPC: C07C7/177
Filed: 1931-06-12
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.

Title: Process for dyeing textile fabric, paper and like materials
IPC: D06P5/02
Filed: 1923-07-03
Abstract: Dyestuffs, such as acid, basic, mordant and substantive dyes, are fixed on textile fabrics, paper &c. and particularly heavy fabrics such as plush, felt, &c., by treatment with hot oil or wax with or without a diluent or solvent, such as toluene, xylene, benzene, benzine, carbon tetrachloride or petroleum, thus obviating the ordinary steam treatment.  Suitable fixing agents are hot wax, oil, paraffin oil, and olive oil, and preferably a mineral oil of boiling point 160-220 DEG  C. applied at a temperature of 80-100 DEG  C.  The process may be applied to cloth-printing, hand-printing, spray-printing, stencilled and hand-painted goods. The material is afterwards dried and the fixing medium thereby evaporated.  Discharge printing may also be similarly treated, the material being dyed and printed with a white or coloured discharge, such as hydrosulphite, in the usual way, and then passed through the fixing bath whereby the dye is fixed and the discharge effected simultaneously.  In the case of basic dyestuffs the treatment with tannin and tartar emetic may be dispensed with.  In a modification of the process a fixing bath of mineral oil of boiling point 160-220 DEG  C. at a temperature of 80-100 DEG  C. is applied to materials which have been dyed, fixed and dried in the usual way, whereby a further fixing is effected.
