Patent GB-391747-A (GB)
Title: Manufacture of aminothiophenols or substitution products thereof
Filed: 1931-07-25
Abstract: 1 : 2- or 1 : 4-Aminothiophenol or a nucleal substitution product thereof is prepared by causing a soluble salt of hydrosulphuric acid with or without the addition of sulphur, to react with 1 : 2- or 1 : 4-nitrochlorbenzene or a nucleal substitution product thereof, the reaction preferably being carried out in aqueous solution.  The reaction appears to take place in two stages, that of substitution and that of reduction and for the sulphide used in the latter stage there may be used sodium disulphide or hydrosulphide.  The solutions of the aminothiophenols may be used directly or the aminothiophenol may be precipitated, for example in combination with zinc and then purified.  Dithioanilines are prepared by oxidation, preferably by atmospheric oxygen in a medium neutral or feebly alkaline and in the solution in which the thiophenol was prepared preferably after partial or complete neutralization.  In examples: (1) p-Chloronitrobenzene is boiled with an aqueous solution of sodium sulphide, any p-chloroaniline formed being carried off by the steam; after cooling zinc sulphate solution is added; the precipitate is dissolved in dilute hydrochloric acid, filtered and separated by the addition of zinc sulphate and salt yielding the zinc compound of amino-4-phenylmercaptan; similarly 2-chloronitrobenzene and 1 : 4 dichloro-2-nitrobenzene yield 2-aminothiophenol and 2-amino-4-chlorothiophenol.  (2) o-Chlornitrobenzene, 1-chloro-4-nitrobenzene, 1 : 4-dichloro-2-nitrobenzene, 1-chloro-4-nitrobenzene-2-sulphonic acid, 2 : 4 - dinitrochlorobenzene are treated as in example (1) omitting the zinc sulphate precipitation.  (3) A solution of 4-aminothiophenol prepared as in example (2) is mixed with sodium bicarbonate to neutralize caustic soda and then oxidized by air to yield p-dithioaniline; o-dithioaniline and p-dichloro-o-dithioaniline may be similarly prepared.  (4) A solution of 1-chloro-2 : 4-dinitrobenzene in alcohol is mixed with an aqueous solution of sodium sulphide and the mixture oxidized by air; the precipitate is dissolved in acetic acid reprecipitated by water, dissolved in hot alcoholic hydrochloric acid, filtered and precipitated by ammonia, the product, crystallized from nitrobenzene, comprising the disulphide of 2 : 2<1> - dinitro - 4 : 4<1> - diaminodiphenyl.  (5) p-Chloronitrobenzene is boiled with a solution of sodium sulphide and sulphur or a solution of sodium sulphide and sodium hydrosulphide to yield a solution containing 4-aminothiophenol.  (6) A solution of 4-aminothiophenol prepared according to example (2) from p-chlornitrobenzene is made slightly acid by means of acetic acid and the 4-aminothiophenol which separates is filtered.

Abstract: 1431946 Separating hydrocarbons STANDARD OIL CO 4 May 1973 [12 May 1972 13 Sept 1972] 21365/73 Heading C5E Aliphatically unsaturated hydrocarbon having 2 to 8 carbon atoms is separated from a mixture by selectively transferring it across a barrier which comprises an aqueous component containing metal ions which combine with the unsaturated hydrocarbon to form a water soluble complex and a semi-permeable member which is solid, water-insoluble and impermeable to the aqueous component; the partial pressure of the unsaturated hydrocarbon on the second side of the barrier being maintained lower than that on the first side so that the unsaturated hydrocarbon is released on the second side of the barrier. The metal ions can be silver, zinc or cuprous ammonium and the aqueous component can comprise silver nitrate, optionally together with UO 2 (NO 3 ) 2  or a nitrate of Cr, Ni, Zn, Cd, Al, Li, Sr, Ca, Mg, Co, Fe<SP>3+</SP>, Na, Pb, NH 4  or K. The semi-permeable membrane can comprise polyurethane, nylon, sodium cellulose xanthate or an ethylene glycol monomethacrylate polymer. The process can be used to separate acetylene and/or ethylene from mixtures which also comprise methane and/or ethane. Many examples are given in which the aqueous component is in the form of a liquid covering the first side of the semi-permeable membrane which is either in the form of a flat sheet or a hollow tube immersed in the liquid; alternatively the aqueous component can be held within the semi-permeable membrane, e.g. by being absorbed therein or absorbed on a material such as cellulose acetate which is held between two semi-permeable sheets.

Patent GB-632744-A (GB)
Title: Process for countercurrent contacting of solid particles and gases
IPC: B01J8/18
Filed: 1947-08-07
Abstract: In processes for contacting solid particles with gases the particles are passed downwardly countercurrently to the gases through a series of one or more contacting zones and one or more heat-exchange zones where the solids are in indirect contact with a heat-exchange fluid, the gas velocity in the contacting zones being such that the particles pass through non-agitatedly and that in the heat-exchange zones being higher, such that the particles therein are maintained in a vibratory state.  Specified processes are the separation of gaseous mixtures by a solid adsorbent, catalytic reactions <PICT:0632744/III/1> wherein the solid is a catalyst and chemical reactions between gaseous and solid reagents.  The higher gas velocity in the heat-exchange zones may be effected by restricting their cross-sectional area in relation to that of the contacting zones, by, for example, the insertion of heat exchange coils.  As applied to the separation of C2 hydrocarbons from a gaseous hydrocarbon mixture by preferential adsorption on charcoal, the gaseous mixture is fed to tower 1 through line 9, charcoal being fed from hopper 2.  The gaseous mixture passes upwardly through adsorption zone 10, the unadsorbed gas being withdrawn at 23. Charcoal passes downwardly through cooling tubes 4, adsorption zone 10, rectification zone 13, stripping zone 14, heating tubes 5, and is withdrawn through line 12.  Stripping gas, e.g. steam, is supplied through line 15 and a mixture of steam and desorbed C2 hydrocarbons is withdrawn at 16, passed through cyclone separator 17, cooler 18 and separator 19, C2 hydrocarbons being withdrawn at 20.  Carbon withdrawn at 12 is returned to hopper 2 in a current of inert or recycled unadsorbed gas 21, with intermediate reactivation, if desired.  The gas and steam velocities in lines 9 and 15 are controlled to effect non-vibratory motion of adsorbent particles in zones 10, 13 and 14 and vibratory motion in tubes 4 and 5. Additional control of gas velocity through tubes 4 may be obtained by recycling a portion of unadsorbed gas by line 27 to distributing-plate 8, and additional control of gas velocity through zone 14 may be effected by byepassing part of the gas rising in tubes 5 around the point at which solids enter the tubes 5.

Title: Process for the purification of amylose
IPC: C08B30/20
Filed: 1964-05-26
Abstract: Substantially fat-free retrograded amylose is prepared by dissolving retrograded amylose in a mixture consisting essentially of water and an alcohol having 4 to 6 carbon atoms, at a temperature of from 250 DEG  F. to the temperature at which amylose tends to degrade, the period during which the solution remains at the temperature being limited to avoid substantial degradation of the amylose, the proportions of water and alcohol in the mixture being such that separable water and alcohol layers can be formed at a temperature below the atmospheric boiling-point of the water-alcohol mixture but at 120 DEG  F. or above the amount of impure retrograded amylose dry substance being not more than 15% by weight based on the weight of the water in the water-alcohol mixture, cooling the solution to a temperature below the atmospheric boiling-point of the water-alcohol mixture but not less than 120 DEG  F., maintaining the solution at a temperature of from 120 DEG  F. to the boiling point of the mixture for a time sufficient to form an upper alcohol layer and a lower water layer, separating the two layers, and recovering substantially fat-free amylose from the water layer.  The water/alcohol mixture is preferably heated rapidly to above 250 DEG  F. by mixing with steam at super-atmospheric pressure.  The mixture may be maintained at a temperature between 120 DEG  F. and the boiling point for a time sufficient to allow solid amylose to form in the water layer, from which it may be separated by conventional methods.  Alternatively, the amylose may be precipitated from the water layer, before any solid amylose has formed, by an organic liquid, e.g. pyridine, alcohols or ketones.  To ensure separation of aqueous and alcoholic layers at the required temperature, the water/alcohol mixture contains not less than 8% alcohol, based on the weight of water. Preferably the weight of impure amylose used is less than 9%, in which case the amylose may be separated from residual branched-chain material, the latter remaining in solution while amylose solidifies in the water layer.  Specifications 895,215 and 923,240 is referred to.
