IPC: C07C46/02
Filed: 1971-04-20
Abstract: 1294422 Recovering manganese salts UNION RHEINISCHE BRAUNKOHLEN KRAFTSTOFF AG 20 April 1971 [2 May 1970] 10131/71 Heading C1A Pure manganese salts are recovered from  manganese salt solutions containing organic impurities by adding a water-miscible solvent which is an alcohol or acetone in which the organic impurities are readily soluble, in an amount governed by the concentration of the manganese salt, to precipitate the manganese salt and separating the precipitated manganese salt from the dilute solution. Optionally, the manganese salt solution is filtered before addition of the solvent. Examples of the solvent are methanol, ethanol, n-propanol, isopropanol and acetone.

Abstract: 1,007,424. Reservoir pens. PARKER PEN CO. Dec. 1, 1961 [Dec. 7, 1960 (3)], No. 43085/61. Heading B6P. A fountain pen of the type having a reciprocating piston self-filling reservoir, Fig. 16; or a replaceable cartridge reservoir, Fig. 15 (not shown), comprises an ink overflow collector in the form of an annular chamber 77 between the outer wall of a hollow generally cylindrical plug 36 and the inner wall of the hollow forward barrel portion 23 of the pen. The plug 36 is mounted on or is integral with means 37 that includes a rearwardly-projecting tubular connector 41 on which the ink reservoir 21 is mounted. A feed bar 33, Figs. 4 and 5, extends from the nib 34 through the plug 36, and into the tubular connector 41, and comprises one capillary groove 51 running from the reservoir to a capillary annular control chamber 56 formed between the wall of the plug 36 and the surface of the feed bar, and two side-by-side capillary grooves 53, 54 running from the control chamber 56 to the nib 34. A non- capillary air channel 61 is provided on the underside of the feed bar allowing air into the control chamber 56. A radial slot 78 of capillary dimensions in the plug 36 connects the control chamber 56 to the overflow chamber 77. Air passes from the central chamber 56 through a wider part 60 of the capillary groove 51 to the reservoir. The plug 36 has at its forward end a counter bore 84 which communicates between the air channel 61 and an air slot 80 in the plug, diametrically opposite the radial slot 78. This allows the feed bar 33 to have any orientation with respect to the plug 36. The nib 34 and the feed bar 33 are mounted in a follow collar member 30 screwed into the forward barrel portion of the pen. An upstanding protuberance 70 spaces the nib from the surface of the feed bar. The nib 34 is semi-conical, tapering to a writing point, and is stepped-down intermediate its ends to provide a rearwardly facing shoulder. The radial slot 78 has greater capillary strength than the control chamber 56, so that the slot 78 and an annular V-groove 82 of the overflow chamber 77 are normally filled with ink. The capillary force exerted by the control chamber 56 is greater than the overflow chamber 77. The feed bar 33 is of a synthetic plastic material such as methyl methacrylate. Other non- metallic parts of the pen, such as the barrel portions, the collar 30, the plug 36, the plug mounting means 37 and both reservoirs are of suitable synthetic plastic material. Reciprocating piston reservoir.-The reservoir 21, shown in Fig. 16, comprises an axially movable piston 46 with a sealing ring 120, a threaded driving member 105 rotatably mounted on the tubular body of the reservoir, and a threaded connection 114 between the piston and the driving member. A rear barrel portion of the pen is screwed on to the forward barrel portion to enclose the reservoir 21 securely mounted on the tubular connector 41, Fig. 1a (not shown).

Title: Fluorinated pyridines
Inventor: CHAMBERS RICHARD DICKINSON
IPC: C07D213/69
Filed: 1964-03-11
Abstract: Pentachloropyridine or tetrafluoropyridine are heated with anhydrous KF in the absence of a solvent to give fluorinated pyridines. Pentachloropyridine gives pentachloropyridine, 3-chlorotetrafluoropyridine and 3,5-dichlorotrifluoropyridine. Mixed tetrachloropyridines give 3 - chloro - 2,4,6 - trifluoropyridine, two isomeric dichlorodifluoropyridines, one of which is 3,5 - dichloro - 2,6 - difluoropyridine, and two isomeric trichloromonofluoropyridines.  The starting materials are obtained by reacting pyridine with PCl5 to give di-, tri-, tetra- and penta-chloropyridines.  The fluoropyridines produced by the above process may be subsequently reacted with ammonia, hydrazine or an alkali metal alkoxide to give a product containing, respectively, an amino, hydrazino or alkoxy group at position 2 and/or at position 4. The compounds produced according to the above processes may undergo further reactions to give other substituted polyfluoropyridines. Thus:-  (a) Pentafluoropyridine reacts at position 4 with pentafluorophenyl magnesium bromide to give 4 - (pentafluorophenyl) - tetrafluoropyridine.  (b) An amino group may be converted to bromo by the Sandmeyer reaction.  (c) 4 - Bromo - tetrafluoropyridine may be treated with copper to give octafluoro-4,41-bipyridyl.  (d) Compounds containing no fluorine at position 4 react at positions 2 and/or 6 with ammonia, alkali metal hydroxides and alkali metal alcoholates to give the corresponding amino, hydroxy or alkoxy compounds.  (e) A hydrazino group at position 4 may be converted to an amino group by reaction with aqueous hydriodic acid, or to a hydrazone by reaction with a carbonyl compound.  (f) An amino group at position 2 or 4 may be converted to -NO2 by reaction with H2O2 and trifluoroacetic anhydride.  (g) 4 - Bromo - compounds may be converted to the corresponding magnesium bromides which then undergo the normal reactions of Grignard reagents.  (h) Bromine may be replaced by hydrogen by treatment with copper (cf. reaction (c) above).  (i) Methoxy groups may be converted to hydroxy by treatment with aqueous hydriodic acid.  (j) Reaction of 4-hydrazino-tetrafluoropyridine with calcium hypochlorite and benzene gives 4 - phenyl - tetrafluoropyridine.  (k) Reaction of pentafluoropyridine with phenyl-lithium gives 4-phenyl-tetrafluoropyridine.  (l) 3,5 - Dichloro - trifluoropyridine is reacted with magnesium and ethylene dibromide, and the Grignard product is hydrolysed to 3-chloro-2,4,6-trifluoropyridine.  Reference has been directed by the Comptroller to Specification 1,059,231.

Title: Process for the mechanical dispersion of alkaline earth and heavy metal salts of the phosphoric and arsenic acids
IPC: C01B25/26
Filed: 1928-04-10
Abstract: 315,254. Chwala, A. April 10, 1928. Colloidal compounds. - Alkaline-earth and heavy metal arsenates and phosphates such as the arsenates of lead, copper, and calcium or the phosphates of calcium may be rendered colloidal by mechanical dispersion by any known means such as beating mills, colloid mills and the like, or a simple agitator, the process being carried out by the use of peptising agents. The agents used are the alkali salts of arsenic and phosphoric acids, which may be regarded as being formed from the corresponding ortho-acid by the removal of water. For example, the following salts are mentioned :-alkali meta-phosphates, especially the salts of the complex meta-phosphates, such as trimetaphosphates, tetrametaphosphates, hexametaphosphates, for instance potassium-sodium hexametaphosphate: alkalipyrophosphates, such as sodium pyrophosphate, alkali-meta-arsenates and alkali pyroarsenates for example sodium pyroarsenate. These agents also include the alkali salts of the corresponding thioacids, in which the oxygen is partly or entirely replaced by sulphur, for example, sodium pyrothio-arsenate has been found very effective. The mechanical treatment may be carried out with advantage in the presence of a protective colloid, and the materials may be comminuted in a dry, moistened or perfectly wet state. If water is present, the paste may be afterwards dried by known methods. The colloidal solution obtained in this manner shows the characteristic Brownish movement.

The CO combustion may be catalysed with Fe, Ni, V, Co or rare earth or oxides or salts of these metals, which may be in the form of particles, linings, screens, or grids and may be mechanically supported. Suitable cracking catalysts are SiO 2  and/or Al 2 O 3 , or MgO or Zn. Particularly useful are SiO 2 /Al 2 O 3  mixtures containing 10-50 wt. per cent Al 2 O 3  optionally mixed with molecular sieves, or clay extended Al 2 O 3 . Suitable molecular sieves are listed. The catalyst may be fed to heat exchange from (a) the cracking catalyst regenerator; (b) a cooler after the regenerator or (c) a stripper of the regenerator, and in addition fresh catalyst may be supplied.
