Patent GB-686536-A (GB)
Title: Method of treating mineral coal distillation benzol
IPC: C10L1/06
Filed: 1949-05-18
Abstract: Crude benzole is sharply rectified, before any chemical purification is effected, into heads boiling below 80 DEG C, benzene boiling within a temperature-range of at most 0.6 DEG C, toluene boiling within a temperature range of at most 0.95 DEG C, and a fraction boiling from 137 DEG  to 200 DEG C; and these products are then chemically-purified or, in the case of the high-boiling fraction, treated to give resins.  The process gives high yields of the purified products; and the high-boiling fraction, which contains styrene, indene and coumarone, polymerizes to give high-melting, pale resins.  In an example, crude benzole, from coke oven gas, was fractionated under atmospheric pressure to give heads (boiling-range, 20-80 DEG C), benzene, and toluene; and the residue was distilled under vacuum to yield a fraction containing the xylenes, styrene, indene and coumarone.  The partially purified benzene was treated successively with sulphuric acid (twice), water and soda-lye; and was then re-distilled without rectification to give a thiophene-free product, 96 per cent of which, on fractionation, distilled-over on a 0.3 DEG C range.  The crude toluene was similarly treated to give a product which contained only traces of thiophene homologues, 96 per cent of which, on fractionation, distilled-over on a 0.6 DEG C range. The fraction obtained under vacuum may be copolymerized according to the method described in Specification 686,537.

Patent GB-591939-A (GB)
Title: Finishing pigment-resin coloured fabrics
IPC: D06P1/44
Filed: 1943-08-17
Abstract: Textile fabrics are coloured over at least a portion of the surface by a light-fast pigment applied thereto by depositing a pigment-resin emulsion thereon and curing the resin, and after-treating at least the pigment-coloured portion with an aqueous solution of an amide-or imide-aldehyde resin alkylated with a polyhydric alcohol and thereafter heating to destroy the water-solubility of the resin.  The after-treatment resin must be water-soluble both before and after alkylation.  At least a portion of the remaining surface may be dyed or over-printed with an organic dyestuff.  Suitable amide- and imide-aldehyde resins are obtained by condensing an aldehyde such as formaldehyde with urea, thiourea, guanidine, biuret, dicyandiamide and melamine, and alkylating with a polyhydric alcohol such as a glycol, glycerol, pentaerythritol, di-pentaerythritol, sorbitol and mannitol.  In an example: (1) a pigmented colour base containing iron oxide yellow pigment, soyabean oil-modified glycerolphthalate resin, a solution of butylated dimethylol urea in xylene/butanol, pine oil, oleic acid and ammonia is reduced with an oil-in-water emulsion of a petroleum fraction in aqueous methyl cellulose solution.  Cotton cloth is dyed or printed with the pigmented emulsion, dried and heat cured and finished by passing through an acid aqueous solution of a urea-formaldehyde resin alkylated with ethylene glycol, drying and heating to 120 DEG  C. for 3 mins.  In example (2), the process is repeated, but using a finishing solution comprising an acid aqueous solution of urea-formaldehyde resin alkylated with glycerol.  In example (3), a pigmented colour base containing copper phthalocyanine, a soyabean oil - modified glycerol-phthalate resin dissolved in a petroleum fraction boiling at 160 DEG  to 250 DEG  C., low viscosity ethyl cellulose, butanol, tricresyl phosphate and aluminium hydrate is blended with a solution of butylated dimethylol urea in petroleum oils reduced with a water-in-oil emulsion containing sodium lignin sulphonate, a soyabean oil-modified glycerol-phthalate resin, toluene, a mixture of petroleum fractions, and acetic acid, and printed or dyed on a cotton fabric.  The fabric is then dried and heat cured, finished with an acid aqueous solution of a melamineformaldehyde resin alkylated with ethylene glycol, dried, and heated to 120 DEG  C. for 3 mins.  In example (4), a pigmented colour base containing dichlorobenzidine yellow, the sodium salt of disulphodinaphthyl methane, bentonite, dimethoxymethyl urea, trimethylol melamine and methyl cellulose is mixed with an oil-in-water emulsion containing a petroleum fraction, methyl cellulose and trimethylolmelamine, and dyed or printed on a cotton fabric, which is dried and heated, and finally treated by passing through a solution of urea-formaldehyde resin alkylated with ethylene glycol, drying and heating to 120 DEG  C. for 3 mins.

Filed: 1929-05-06
Abstract: 326,400. Triggs, W. W., (American Machine & Foundry Co.). May 6, 1929. Tobacco.-In order to counteract the shrinkage of tobacco during curing, the cured and conditioned tobacco is subjected to the action of a gas under pressure to cause the gas to penetrate the tobacco, and the pressure is suddenly released to cause expansion of the tobacco. The gas may be air, carbon dioxide, steam, &c., at a temperature of about 110‹ C. and under a pressure of about 20 lbs., and may carry a tobacco-treating medium. In the apparatus shown, tobacco is placed in a removable perforated container 3 spaced from the walls of a jacketed chamber 4 having a steamtight cover 5. Steam may be admitted to the jacket through a valve 34 to heat the chamber 4. Gas under pressure is admitted to chamber inlet 11 from a supply pipe 30 through valves 29, 13 and passages 15, 16. The valve 29 is a three-way valve which can be used to admit gas from the pipe 30, treating medium from a pipe 32, or both. The valve 13 also admits the gas to the rear face of a piston valve 12, which is held on a seat 18 until the pressure is relieved by opening a valve 14 leading to an outlet 23, when the gas in the chamber 4 can escape through the outlet 23. The chamber 4 may be exhausted, by means of a suction pump connected to a valve 36, before opening the gas admission valve 29.
