Patent GB-193802-A (GB)
Title: A process for the purification of hydrocarbons
IPC: C10G21/10
Filed: 1922-05-04
Abstract: 193,802. Allgemeine Ges. f³r Chemische Industrie. Feb. 21, 1922, [Convention date]. Mineral and tar oils, purifying; paraffin and mineral waxes, extracting and purifying.-In the extraction or purification of hydrocarbons by liquid sulphur dioxide the crude material is treated successively in the same vessel with progressively purer quantities of dioxide. Applications specified are the purification of lubricating oil distillate, to obtain electrical transformer oils, the separation of paraffin wax from lignite tar or tar oils, and the purification of crude anthracene and crude montan wax. Using the apparatus shown for the separation of paraffin wax, the lignite tar or oil is mixed and cooled to -10‹ C. in an extractor a with several volumes of twice-used liquid sulphur dioxide from a reservoir d, and allowed to settle. The precipitated hard and soft paraffins rise to the surface, while the sulphur-dioxide extract settles below the oil and is withdrawn through a filter-press b to a still c. A second extraction with once-used dioxide from a reservoir e is then made, the extract being run off to the reservoir d. Finally, pure dioxide from the condenser g and reservoir h is mixed with the oil in the extractor, and the temperature raised to 40‹ C. to melt the layer of paraffin. The extract is run off to reservoir e and the liquid paraffin to a still f. A second extractor adjoining extractor a may be maintained at 40‹ C. and used solely for the final extraction. As anthracene and montan wax cannot readily be melted in the extractor a they are washed out and into the still f by a little pure sulphur dioxide.

Title: Process for the production of regenerated cellulose fibres with improved textile properties
IPC: C08L1/24
Filed: 1960-04-08
Abstract: Condensation products, made by etherification of methylol compounds of amino triazines with polybasic alcohols and by further heating the initially-formed water-soluble ether products up to a degree of condensation at which the water-diluability of the reaction mixture decreases as low as 5-1,5 times its weight, are added to viscose prior to spinning in conventional manner. Compounds specified are made by condensation of melamine, ammeline or guanamines with formaldehyde, followed by etherification with glycol, glycerol, trimethylolpropane or pentaerythritol and further heating as described above.  From 1 to 8% by weight of the condensation product, based on cellulose, may be included in the viscose.  In an example, 4% by weight, based on the cellulose, of a condensation product made from ethylene glycol, melamine and formaldehyde is incorporated in a viscose containing 8,5% of cellulose, 7% of sodium hydroxide and 32% of carbon disulphide (based on the cellulose), which is spun at a salt point of 4,8 into a coagulating bath containing 100 g./l. of sulphuric acid, 25 g./l. of zinc sulphate and 240 g./l. of sodium sulphate.  The fibres formed are after-stretched in hot water to induce crimping, treated with a 12 g./l. zinc chloride solution to harden the condensation product and dried.  Fibres so made have a lower swelling factor, higher relative wet strength and better crimping resistance than conventional regenerated cellulose fibres, and are p  dyed readily with acid wool dyes.  German Specifications 844,634, 1,044,345 and U.S.A. Specifications 2,654,715 and 2,684,343 are referred to.
