Patent GB-532215-A (GB)
Title: Improvements in the manufacture of cellulose derivatives and of artificial filaments, foils and other articles therefrom
IPC: C08B3/16
Filed: 1939-08-22
Abstract: 532,215. Cellulose derivatives ; artificial filaments, films, &c. OLPIN, H. C., GIBSON, S. A., and JONES, J. E. Aug. 22, 1939, No. 24163. [Classes 2 (ii) and 15 (ii)] Cellulose derivatives having an affinity for acid dyestuffs are obtained by subjecting cellulose to the action of a medium comprising a halogenated organic acid and the anhydride of another organic acid so as to form a mixed ester and then reacting the ester with an organic base. Prior to or after the reaction with the organic base, the cellulose mixed ester may be converted into artificial filaments, foils, or other articles. The mixed ester is preferably one which contains not less than 5 per cent. of chloroacetyl radicle, calculated as chloroacetic acid, or an equivalent quantity of halogen if present in another halogenated acid radicle. In an example, cotton linters are pre-treated with formic acid and then esterified with a mixture of acetic anhydride, acetic acid, monochloroacetic acid and sulphuric acid. The primary ester is ripened to produce a secondary ester containing 2-2.3 acetyl groups and about 0.2 chloroacetyl groups per glucose unit. This is dissolved in acetone and spun into filaments. The filaments are treated for several hours with a hot solution of pyridine dissolved in toluene. Instead of treating the filaments with pyridine, the ripened ester in powder form may be treated in the same way with a solution of pyridine in toluene and the product may be dissolved in a mixture of methylene chloride and methylated spirit and spun into filaments. The yarn obtained may be dyed with acid dyes e.g. Orange II, Guinea Fast Red BL, Solway Ultra Blue B, Solway Green GS, Alizarine Cyanine Green G, or Azo Acid Black 3BL. The yarn may also be dyed with the water-insoluble cellulose acetate dyestuffs, and it has some affinity for direct cotton colours. Instead of acetic anhydride there may be used propionic or butyric anhydride and instead of chloroacetic acid there may be used chloropropionic, chlorobutyric, or other halogen substituted lower fatty acid. Other organic bases which may be used include di- and tri-ethylamines, piperidine, and quinoline. The yarns may be associated, before or after treatment with the organic base, with cellulose acetate yarns or with wool, cotton, or regenerated cellulose yarns to produce yarns or fabrics which can be dyed to produce solid, resist, or cross-dyed effects.

This metal other than iron, is stated to be in the form of a ferrite in the final product.  By heating the material in oxygen or air at about 300 DEG C for one hour, and cooling in air or water, the Fe3O4 may be converted into Fe2O3.
Patent GB-588270-A (GB)
Title: Improvements in or relating to textiles and methods of treating the same
IPC: D06M15/70
Filed: 1944-12-06
Abstract: 588,270. Shrinking fabrics. SYLVANIA INDUSTRIAL CORPORATION. Dec. 6, 1944, No. 24381. Convention date, Dec. 8, 1943. [Class 42 (i) ] [Also in Group IX] Pre-shunk fabrics are made by weaving a fabric with warp and weft containing potentially adhesive fibres of such different character that those in either set of yarns may be " activated," i.e. rendered adhesive, independently of those in the other set, shrinking the fabric, and rendering the shunk structure permanent by activating and de-activating the potentially adhesive fibres. The fabric may be shrunk successively in the warp and weft directions, or in both simultaneously, and the two types of potentially adhesive fibre may be activated in separate operations or simultaneously. The potentially adhesive fibre may consist of any thermo-plastic or solvent-plastic synthetic resinous or cellulosic material which is non- tacky at room temperatures but may be rendered adhesive by heating or by a solvent which does not render tacky the non-adhesive fibres with which it may be associated. Examples are given in which shrinkage is effected by stretching a moistened fabric in one direction whilst allowing it to shrink in the other, or by causing shrinkage by mechanical compression on one set of yarns, the shrunk yarns or both sets of yarns being activated by heat or solvents, and subsequently de-activated. The fabric then treated to shrink it in the other direction, activation being under such conditions that only the yarns which are now subjected to shrinkage are affected. Or, one set of yarns may comprise pre-stretched filaments; mechanical pressure is exerted on the other set of yarns, and activation of both sets takes place at such a temperature that the pre-stretched yarns shrink, so that the fabric is simultaneously shrunk in both directions. In the case of thermosetting resin filaments, de-activation may be accomplished by heating for a longer time or to a higher temperature, in the case of thermoplastic fibres by cooling or removal of solvent or plasticizer. The fabric is preferably subjected to pressure during activation. Specifications 326,735, [Class 42 (i)], and 545,770 are referred to.

Title: Improvements in and relating to the hydrogenation of carbonaceous materials
IPC: C10G1/06
Filed: 1932-09-05
Abstract: In the hydrogenation of carbonaceous materials, e.g. benzols, petroleum residues, coal tar, wood meal, bituminous coal by nascent hydrogen produced in the reaction system by the decomposition of water by finely divided metals, e.g. iron, substances (excluding zinc salts) having an acid reaction are added as accelerators for the formation of the nascent hydrogen. Suitable accelerators include magnesium chlorides, ammonium chloride, alkali borates, and chlorides of iron, chromium, nickel and manganese, or solutions containing an acid reacting salt, e.g. the residual liquor from the potash industry containing magnesium chloride.  10 parts of petroleum residues boiling above 350 DEG  C. mixed with 3.5 parts finely divided iron and 2 parts MgCl2 solution are pumped into a pressure reaction vessel maintained at 450 DEG  C. and a product is obtained of which 40 parts boil below 180 DEG  C. and 30 parts below 300 DEG .  Raw benzol similarly treated yields a product having a 25 per cent greater benzol fraction boiling below 150 DEG .  Brown coal tar containing phenols is similarly treated in the presence of 6 parts iron, and 3 parts of a 6 per cent sodium borate solution.  100 parts of wood meal treated with 80 parts iron and 40 parts of a 2 per cent magnesium chloride solution obtained as a diluted end liquor from the potash industry yield 50 parts oil.
