Title: Manufacture of benzimidazolone-stibinic acids
IPC: C07F9/90
Filed: 1930-02-19
Abstract: o-Diacyldiamino-aminobenzenes are prepared by the catalytic reduction of o-diacyldiamino-nitrobenzenes.  Thus, 3 : 4-diacetyldiamino-1-aminobenzene is obtained by treating 3 : 4-diacetyldiamino-1-nitrobenzene in alcohol solution with hydrogen under pressure in the presence of a nickel catalyst.ALSO:Benzimidazolone-stibinic acids are prepared by treating an o-diaminobenzene-stibinic acid with sufficient of a chloroformic ester to react with one amino group only and then heating the resulting urethane in the presence of an acid.  An example is given of the preparation of 2-oxobenzimidazole-2 : 3-dihydride-5-stibinic acid from 3 : 4-diaminobenzene-1-stibinic acid and chlorocarbonic acid ethyl ester.  o-Diaminobenzene-stibinic acids are obtained by acylating an o-diamino-nitrobenzene, catalytically reducing the nitro group to the amino group, replacing the latter by the stibinic acid residue, and saponifying the products.  Thus, 3 : 4-diamino-1-nitrobenzene is acetylated, the resulting 3 : 4-diacetyldiamino-1-nitrobenzene then catalytically reduced in alcohol using hydrogen under pressure and a nickel catalyst to 3 : 4-diacetyldiamino-1-aminobenzene, which is then diazotized and transformed in known manner into 3 : 4-diacetyldiaminobenzene-1-stibinic acid, from which saponification with caustic soda yields 3 : 4-diaminobenzene-1-stibinic acid.

Patent GB-711519-A (GB)
Title: Improved process for the manufacture of artificial products, such as threads, fibres, films, foils and like products from viscose
IPC: D01F2/06
Filed: 1952-03-05
Abstract: Artificial filaments, threads, fibres, films, foils and other articles are obtained by extruding an alkaline, zinc-containing cellulose xanthate solution, substantially free from sodium trithiocarbonate, into a coagulating bath, and then regenerating the cellulose in the formed articles.  The filaments or other articles may be stretched and subjected to washing and other after-treatments and then dried.  A solution of ammonium sulphate may be used for a coagulating bath in which but little regeneration to cellulose takes place, and an acid solution containing salts such as sodium sulphate, magnesium sulphate and zinc sulphate, may be used for completing the regeneration to cellulose.  Alternatively, a single bath in which coagulation and regeneration take place may be used.  Such a bath may comprise sulphuric acid and sodium, magnesium and zinc sulphates.  If desired the coagulation may be effected in a solution of acetic or formic acid with or without an addition of a salt.  Stretching of the freshly coagulated but incompletely regenerated articles may take place in a hot medium such as hot water or water vapour.  In preparing the spinning solution, the xanthated alkali cellulose may be washed with a solution of an alkali metal salt, in which the cellulose xanthate does not dissolve, and the purified cellulose xanthate may be treated with a dilute zinc salt solution.  After removing excess of the zinc salt solution, the cellulose xanthate is dissolved in an alkaline solution.  If desired, the cellulose xanthate which has been washed with a solution of an alkali metal salt may be dissolved in a zinc-containing alkaline solution. Alternatively, a normally prepared viscose may be coagulated, with substantially no regeneration, and if desired it may be formed into filaments by extrusion; the coagulate may be washed to remove trithiocarbonate and then treated with a dilute zinc salt solution, and after removing the excess of zinc salt solution, the cellulose xanthate may be dissolved in an alkaline solution.  Coagulation of the cellulose xanthate solution may be effected with solutions of ammonium sulphate, or chloride, or with bisulphite solutions, or with gaseous reagents such as sulphur dioxide, or carbon dioxide. Trithiocarbonate-free cellulose xanthate may also be obtained by dialysis of normally prepared viscose.  A solution of zinc sulphate may be used for loading the purified cellulose xanthate.

Abstract: 511,859. Hydraulic power transmitters. DAIMLER-BENZ AKT.-GES. Feb. 24, 1938, No. 5899. Convention date, March 11, 1937. [Class 69 (ii)] A hydraulic coupling of the F÷ttinger type is characterised by the provision in one or both of the coupling ports of cooling passages communicating with a space separate from the working chamber but communicating therewith, said space being also provided with small outlet ports, the arrangement being such that the working liquid must flow through the cooling passages before passing into the working spaces of the coupling and that a continuous flow through the cooling passages, separate space and outlet ports can be maintained, even though the working spaces are wholly or partially emptied. Working liquid is supplied through line l to a space m in the interior of the driven shaft g, and thence under the influence of centrifugal force through passages n in the driven member f of the coupling to a space o which communicates at p, q with the working spaces d, e and is provided with outlet ports r. The driving member b may be driven by an internal combustion engine through gearing c, and the driven shaft g may drive a supercharger for the engine. Two auxiliary supply pumps i, k are provided, driven in common by the internal combustion engine, and connected in parallel between the tank h and supply line l; the output of the pump k can be diverted from the line l by a cock t, which may be automatically clutched, to decrease the filling of the coupling, the liquid so diverted being sprayed through pipes v, w, x against the exterior of the driving member b of the coupling to effect cooling thereof. A single pump may be used in conjunction with a cock for diverting some of its delivery. In a modification, Fig. 2 (not shown), passages are provided in the driving member, in addition to those in the driven member, for conveying liquid from the interior of the driven shaft to the space communicating with the working spaces. In a further modification, Fig. 3 (not shown), the supply to the working spaces is through the passages in the driven member only, but the driving member is also provided with passages through which the liquid diverted, when the filling is to be reduced, is circulated. Specification 511,858 is referred to.

Title: Process for the recovery of hydrocyanic acid and ammonia
IPC: C01C3/04
Filed: 1952-03-06
Abstract: <PICT:0706659/III/1> Hydrocyanic acid and ammonia are separately recovered from a gaseous mixture thereof with water vapour by subjecting the gaseous mixture to a counter-current washing with water at 60-95 DEG C., and hydrocyanic acid and ammonia are withdrawn separately from the distillation stage as gas and aqueous solution respectively.  A gas mixture containing hydrocyanic acid and ammonia, with or without CO2 and H2S, may be dissolved in wash water to separate inert gases, and a water vapour mixture of these gases, produced therefrom by treatment with steam after heating in a heat exchanger, is passed into a still 1 at 6, some of the ammonia goes into solution in packed section 2, and the residual gases pass upwardly through packed section 3, where further NH3 is dissolved by water at 83 DEG C. entering through sprinkler 7.  The remainder of the NH3 is removed in section 4, which with section 5 has dish-shaped trays, by water at 60 DEG C., which may be by-passed through jacket 8 from the feed to sprinkler 7, entering through sprinkler 9 and by aqueous HCN refluxing from section 5.  HCN, with CO2 and H2S if present, passes from the head of the column through reflux condenser 10, where the gases are cooled to 26-30 DEG C.  Most of the HCN may be recovered from the head gases by cooling to -10 DEG C. and liquefying, and the remainder by water washing. Aqueous NH3 collects at the base of the column where direct steam enters at 11 to drive out traces of HCN and maintain a pressure 0.1 atmosphere above atmospheric in still 1.  The aqueous NH3 is removed at 12 and may be concentrated or NH3 separated.  The water after removal of NH3 may be returned to sprinkler 7.  Examples also refer to the treatment of a gaseous mixture obtained by rapid evaporation of aqueous solutions of ammonium cyanide and ammonium carbonate, with and without ammonium sulphide and to the use of wash waters at other temperatures within the specified range.
