Title: Hydrogenated mononuclear heterocyclic carboxylic acids and their salts
IPC: C07D211/60
Filed: 1934-03-21
Abstract: Alkali salts of mononuclear heterocyclic carboxylic acids are hydrogenated by treatment witk hydrogen for instance at 100--250 DEG C. and preferably under pressure, in presence of a nickel catalyst in which preferably at least part of the nickel is in the metallic state.  The free hydrogenated acid may be obtained from its salt by treating with a mineral acid.  The catalyst may be prepared by reducing nickel hydroxide, oxide, carbonate or other salts, preferably supported on a carrier, with hydrogen at 350--500 DEG  C. Other catalysts such as copper, cobalt or iron may be associated with the nickel, or the nickel may be partially combined with a difficultly reducible metal oxide serving as promoter and support, for instance precipitated nickel chromate may be reduced with hydrogen at 350--500 DEG  C.  In examples: (1) aqueous pyromucic acid is neutralized with caustic soda and hydrogenated at 110--120 DEG  C. and 2000 lb. pressure with a nickel-kieselguhr catalyst; (2) aqueous sodium nicotinate is hydrogenated at 190 DEG  C. and 120--170 atmospheres with the same catalyst.  The Specification as open to inspection under Sect. 91 includes the hydrogenation of quinolinic acids and the like.  This subject-matter does not appear in the Specification as accepted.ALSO:Alkali salts of mononuclear heterocyclic carboxylic acids are hydrogenated by treatment with hydrogen, for instance at 100--250 DEG  C., and preferably under pressure, in presence of a nickel catalyst in which preferably at least part of the nickel is in the metallic state.

Patent GB-631002-A (GB)
Title: Improvements in or relating to the production of compounds of alginic acid and its derivatives
IPC: D01F9/04
Filed: 1947-04-02
Abstract: Alginic filaments, films, or other products which when first formed are soluble in alkaline liquids such as soap or soda solutions are rendered resistant to such liquids by swelling them in water, displacing the water by a polar solvent, e.g. methanol, which maintains them in a swollen state sufficient to keep the hydroxyl groups in the alginic molecules accessible to chemical reagents, and then reacting them with a solution of an organic di-isocyanate in a non-reactive polar solvent so that cross-linking of the alginic molecules is effected.  Acetone, or methyl ethyl ketone may be used as non-reactive polar solvent. When the filaments are of alginic acid, the treatment with di-isocyanates does not give fire-proof products but the products may be rendered fire-proof by causing them to react with calcium, chromium, or beryllium acetate.  The alginic products contain carboxyl groups and may be used as ion exchange materials.  In an example, calcium alginate yarn is soaked in water and then freed from water by successive immersions in methanol.  The yarn is centrifuged and then boiled under reflux with a solution of hexamethylene di-isocyanate in acetone.  Specifications 573,591, 575,611, 586,549 and 621,362, are referred to.ALSO:Alginic acid or salts thereof in powder, filament, film, or other form, are rendered resistant to the solvent action of alkaline liquids such as soap or soda solutions by swelling them in water, displacing the water by a polar solvent such as methanol which maintains them in a swollen state sufficient to keep the hydroxyl groups in the alginic molecules accessible to chemical reagents, and then reacting them with a solution of an organic di-isocyanate in a non-reactive polar solvent so that cross-linking of the alginic molecules is effected.

Abstract: 656,480. Optical apparatus. STERN, K. G. March 31, 1948, No. 9063. Convention date, April 3, 1947. [Class 97 (i)] An optical apparatus for analysing a liquid by the moving boundary method comprises a chamber which can be refrigerated and maintained at substantially zero relative humidity and which contains a line source of visible or infra-red radiation, a vessel for supporting a column of the liquid to be analysed, an optical system for projecting the radiation through opposed transparent walls of the vessel and through said liquid, a rotatable diaphragm located in the path of the radiation emerging from said liquid column and having a radiation transmitting portion and a radiation intercepting portion, and a radiation detecting member positioned beyond said diaphragm in the path of said radiation. As shown, the apparatus comprises a refrigerator cabinet 11 in which is supported a tank 13 containing a constant temperature bath. In this bath is immersed a vessel 19 containing the liquid to be analysed, such vessel being for example an electrophoresis, diffusion or adsorption cell. Through a transparent portion 20 of vessel 19 is projected by means of a lens 25 and mirror 29 radiation emitted by a source 30 and passing through a slit 32. The radiation from the liquid passes through a window 23 in tank 13 and is directed downwards at 35 on to a diaphragm 39 which is rotatable through gearing actuated by an external knob 47. Diaphragm 39 has the form shown in Fig. 4, wherein the parts 64, 65, 66 and 67 are transparent to the radiation from source 30. After passing through the diaphragm the light passes through a lens 48 and is then turned through a 180 degrees by mirrors 49, 54 to travel upwardly through a cylindrical lens 55 on to a translucent or fluorescent screen or photographic plate 57 via a mirror 52. The lens 25 forms an image of the source 30 at the diaphragm 39 ; lens 48 is focused on the window 20 in vessel 19 and projects an image thereof on to the screen or plate 57; and the cylindrical lens 55 is focused on the diaphragm 39 and is arranged with its geometrical axis normal to the path of the radiation. Lens 25 may be replaced by two lens 25 and 25<SP>1</SP> arranged so that the radiation travelling therebetween is parallel and diaphragm 39 may be positioned at 391.
