Title: Improvements in the manufacture and production of vat dyestuffs of the anthraquinone series
Filed: 1935-06-12
Abstract: Vat dyes are prepared by reacting anthraquinone-1(N).2-pyridones which contain in the 4-position halogen atoms or nitro, amino or mono-alkylamino groups with aromatic or heterocyclic primary amino compounds, or in reacting anthraquinone-1(N).2-pyridones which contain in the 4-position an amino or monoalkylamino group with aromatic or heterocyclic compounds containing halogen atoms, the dyestuffs obtained being aftertreated with acid condensing agents of the type of anhydrous aluminium chloride or with alkaline condensing agents if desired. Initial materials specified are 4-halogen-, 4-nitro-, 4-amino-, or 4-alkylamino - anthraquinone - 1(N).2 - pyridones.  The reaction is generally carried out at elevated temperature, preferably in the presence of a diluent such as nitrobenzene or naphthalene and of a salt having a basic action such as an alkali metal acetate. The dyes are fast to light and chlorine. In examples: (1) 4-chloranthraquinone-1(N).2-pyridone is condensed with benzidine (dyes cotton blue-green), or 1-aminoanthraquinone (violet-grey), the latter product being heated with aluminium chloride and pyridine (olive-grey); (2) 4-bromanthraquinone-1(N)-2-pyridone is condensed with 1 - amino - 4 (or 5) - benzoylaminoanthraquinone or 1.4-diaminoanthraquinone and the products heated with aluminium chloride and pyridine (olive or brown or grey respectively); (3) 4 - bromanthraquinone - 1(N).2 - (Py.4 - phenyl)-pyridone or the corresponding (Py.4-methyl) compound is condensed with 1-amino-5-benzoylaminoanthraquinone (brown) and heated with aluminium chloride as above (brown-violet); (4) 4-aminoanthraquinone-1(N).2-pyridone is condensed with 4-chloroanthraquinone-1(N).2-(Bz-dichlor)-benzene-acridone (cf. example 1 of Specification 346,676) (blue-grey) or with Bz1-brombenzanthrone followed by heating with caustic potash and ethanol (brown).  The anthraquinone -1(N).2-pyridones used as starting materials may be prepared according to Specification 445,467.  The Provisional Specification also mentions 4-arylamino-anthraquinone - 1(N) - 2 - pyridones as starting materials.  4-Brom-1-acetamino-2-benzoylanthraquinone is obtained by brominating 1-amino-2-benzoylanthraquinone in boiling glacial acetic acid.  4-Brom-1-acetamino-2-acetylanthraquinone is obtained by brominating 1-acetamino-2-acetylanthraquinone, which is obtained by treating 1 - amino - 2 - acetylanthraquinone with acetic anhydride in presence of concentrated sulphuric acid at room temperature.  4 - Aminoanthraquinone - 1(N).2 - pyridone is obtained by the reaction of a 4-halogenanthraquinone - 1(N).2 - pyridone with an aryl sulphamide, followed by splitting with acid.

Title: Apparatus and method for the electrolysis of alkali metal salts
IPC: C25B9/14
Filed: 1958-05-27
Abstract: An electrolytic cell, Fig. 1, comprises a metal disc 1 adapted to rotate horizontally and an anode 7.  Mercury issues through apertures 5 and forms a thin layer over disc 1 by centrifugal force.  An aqueous solution of alkali metal salt (e.g. sodium chloride) is electrolysed in chamber 13, the layer of mercury on disc 1 acting as cathode.  Sodium amalgam is thereby formed which passes through trap 12 into chamber 14 where it flows over blocks of amalgam decomposing material 21 made of graphite or sintered iron and graphite in the presence of water introduced through inlet pipe 22 to yield mercury and a solution of caustic alkali which latter is discharged through outlet pipe 23.  The mercury collects in reservoir 18, and is pumped by pump 20 into chamber 2 and thence passes through apertures 5 to enter upon a further cycle.  Figs. 3 and 4 show electrolyses assembly <PICT:0852597/III/1> <PICT:0852597/III/2> <PICT:0852597/III/3> similar in principle to that in Fig. 1 but where the mercury is recycled by a pump situated outside the cell instead of within it (as in Fig. 1).  Two or more cells as described above may be superposed vertically, the arrangement being such that the amalgam decomposition chamber of the upper cell body is coupled to the electrolytic chamber of the cell body below via a mercury seal in such a way that decomposed mercury formed in the amalgam decomposition chamber of the upper cell is transferred to the electrolytic chamber of the cell below through the said seal. Apparatus comprising three cell units arranged in this way is shown in Fig. 3.  The anode in a cell according to the invention may be so constructed that it may be rotated in the same or a reverse direction relatively to the iron disc.

To eliminate the effect of friction on stop 60, Fig. 8, cylinder 58 is connected by a bourden spring 61 to the baffle plate 62 of a device having a nozzle 63 which is fixed to a spring bellows 64. The nozzle is connected to the diaphragm housing 68 by conduits 66, 67, and air is supplied at 68 and 70. In operation, air is supplied to bellows 64 through conduit 70, and the bellows expand against the action of spring 65. The distance between nozzle 63 and plate 62 is reduced, which allows an increase in pressure in conduit 67 and therefore increases the pressure in cylinder 58, and in stop 60. The higher pressure causes springs 61 to expand further so that plate 62 moves away from nozzle 63, until a state of equilibrium is reached. The working pressure is greater than the pressure of the air supply, by a factor of between 100 and 1000.

Sealing means for a floating roof tank 20 has a sealing element which closes the space between the roof and wall of the tank and which is urged into sealing engagement by bowing a flexible beam 84 by expanding means which reacts on the beam's ends. The tank 20 is cylindrical and the roof comprises a thin conical raft supported by an annular caisson around its edge (Fig. 1, not shown). The caisson is divided into bulkheads whose outer walls form the inner wall of a crawl-gallery to whose outer wall 75 and roof 79 are bolted at 104 and 105 the edges of a sheet of rubber fabric sealing material 27-49-28 (Fig. 8). Part 49 of the fabric is held against the tank wall by a series of spaced flexible metal plates 85 mounted on shoes 40 which are on pivoted arms 72 spring- loaded at 76. Alternatively, to the spring 76, the space inside the crawl-gallery may be ballasted with fluid whose pressure holds the shoes and the fabric against the wall (Fig. 10, not shown). Alternatively also, the outer side of the fabric in the region of the shoe 40 may have externally fluid-filled hollow contact ribs circumferential of the tank (Fig. 11, not shown). The beams 84 are carried between vertical rollers 82 and clips 68 bolted on to the shoes 40, Fixed inside the wall of the tank and evenly spaced between sets of shoes are six vertical rails 35, shown in section in Fig. 3 on which guide-boxes 36 can rise or fall to conform with the fluid level in the tank. The boxes 36 are expansibly connected to the roof by H beams which project radially inwards from them and are held between two pairs of vertically superimposed rollers 55 and 56 which suspend below the floor of the crawl-gallery (Fig. 4, not shown). Other rollers 50, 51 centre the boxes 36 on the racks. The boxes also confine resilient blocks 44, 45 which anchor the ends 48 of the fabric 49 and whose sides are urged inwards by leaf springs (Fig. 7, not shown) to grip the rail. Fluid motors 94 are pivoted on either side of a plate 97<SP>1</SP> on each box 36 and connect with the ends 90 of the beams 84, where they are supported by a roller 89 running along rails extending laterally from the shoes 40.
