Patent GB-913151-A (GB)
Title: Vapour phase oxidation of titanium tetrachloride
Inventor: EVANS ARTHUR WALLACE
IPC: C01G23/07
Filed: 1958-03-06
Abstract: In the production of titanium dioxide by passing a titanium halide together with oxygen or air upwardly through a bed of inert solids to fluidise them, the velocity of the gas and vapour stream is maintained at such a value that the bulk of the reaction is effected above the surface of the bed, whereby a zone of higher temperature is established above the bed.  The bed may be made up of particles of silica, alumina, zircon or rutile and the reaction chamber preferably has a perforated base below which air or oxygen is fed.  Additional oxygen may be fed in admixture with the titanium tetrahalide feed, which may pass through a part of the perforated base or be fed from a point above the base. Alternatively titanium tetrahalide may be fed from the side or the top of the reaction chamber, and injected as gas or liquid into the bed just above the base through tube jets; part of the tetrahalide feed may be in liquid form from the top of the bed. Titanium tetrachloride is usually employed but the tetrabromide or tetraiodide may be used.  The reaction is generally self-sustaining, but fuel gases such as carbon monoxide may be admixed with the tetrachloride reactant.  The temperature in the bed is normally from 700 DEG -1200 DEG C. whilst the temperature above the bed is slightly higher.  Molar ratios of tetrachloride to oxygen may be from 1-0,2 to 1-3.  According to an example a vertical shaft reaction chamber containing zircon sand was fed with titanium tetrachloride vapour through four central inlets from a common manifold, and oxygen through eight inlets on both sides of the tetrachloride ports.  The bed was preheated to 970 DEG C. and on reaction fell to 930 DEG C. whilst the temperature above the bed was about 990 DEG C. Specification 761,770 is referred to.

Abstract: 1359162 Dip-moulded rubber DUNLOP Ltd 29 Feb 1972 [17 March 1971] 7340/71 Heading B5A [Also in Division B2] A method of coating a substrate layer on a former with a gelled rubber latex, comprising subjecting the layer to a hot fluid to heat the layer, and then bringing the heated layer into contact with a heat-sensitized rubber latex, the temperature of the layer being sufficient to gel the latex. The former may be porcelain and glove-shaped. The substrate layer may be a fabric stitched in the form of a glove lining or may be made by immersing the heated former in a latex to form a gelled latex layer. The layer may be steam heated or preferably dipped in hot water to be heated to a temperature 60 to 75‹ C. above the gelling temperature of a heatsensitized latex dispersion in which the layer is subsequently dipped at least in part. The gelled heat-sensitized latex is then dried and cured and the so formed article stripped from the former. Heat sensitizing agents mentioned are polyvinylmethyl ether and polyoxypropylene glycol.

Abstract: The invention comprises compounds of the general formula <FORM:1101213/C2/1> in which R1 represents a halogen-substituted aryl-lower alkyl group, and R2 represents an alkyl, alkenyl or hydroxy alkyl group containing 1-6 carbon atoms.  They may be prepared by converting a primary amine of the general formula R1NH2 by the action of CS2 in the presence of an alkali, e.g. an alkali or alkaline earth metal hydroxide or carbonate, into the corresponding dithiocarbamic acid salt, and then reacting this salt with formaldehyde and the salt of an amine of general formula R2NH2, e.g. the hydrochloride, sulphate, amido-sulphonate, phosphate, acetate or propionate. The reaction is suitably carried out in water or a polar organic solvent, e.g. methanol, ethanol, acetone, dioxan, tetrahydrofuran or acetonitrile. Examples are given in which the group R1 is 4-chlorophenylethyl, 4-fluorophenylethyl, g ,g -bis - (4 - chlorophenyl) - propyl, 3,4 - dichlorobenzyl, 4 - fluorobenzyl, 3,4 - dichlorophenylethyl, 4-chlorobenzyl and 2,4-dichlorophenylethyl, and the group R2 is b -hydroxyethyl,g -hydroxypropyl, n-butyl, n-hexyl, methyl, allyl and isobutyl.

Abstract: 1,072,869. Stripping liquids. EDWARDS HIGH VACUUM INTERNATIONAL Ltd. Feb. 21, 1966 [Feb. 23, 1965], No. 7812/65. Headings B1B and B1M. A liquid is stripped of gas and volatile liquids entrained therein by applying the liquid to the top surface of a rotating porous supporting member such that the liquid flows over it in film form and applying steam, or another vapour, to the opposing surface of the member, the steam passing through the member and causing turbulance of the liquid to promote removal of gas and volatile components. The vapour steam is cooled on a condenser 9 and the condensate removed through pipe 8, any residual unvapourated vapours being removed via line 7 by a vacuum pump which also maintains a required pressure in the chamber 1. To assist stripping the liquid may be preheated by a radiant heater within the chamber or indirectly by heating the porous member. Alternative constructions of the porous member are shown in Figs. 2-5.

Patent GB-350573-A (GB)
Title: Method of treating recovered sulphur
IPC: C01B17/02
Filed: 1930-03-15
Abstract: Sulphur obtained from mineral deposits is freed from arsenic, antimony, chlorine and similar impurities by treating molten sulphur with reagents, in a powdered form or in concentrated solution, which will form with the impurities compounds insoluble in the sulphur, intimate contact being effected by vigorous agitation.  The reagents employed are metallic oxides, hydroxides, carbonates and sulphides, particularly those of the alkali and alkaline-earth metals.  In carrying the invention into effect, sodium hydroxide, sulphide, carbonate or bicarbonate is employed in slight excess of the amount required to form sodium thioarsenate.  If lime be employed, a suspension of one part of lime to five of water is used.  With an aqueous solution, the material is maintained at 125-135 DEG  C. to cause the water to evaporate.  Acceleration of the reaction is caused by bringing it about under pressure.  Two or more reagents may be used together or in succession, e.g. sodium carbonate or lime may be used to remove the major part of the impurity and sodium hydroxide or sulphide for the remainder.  Separation of the sulphur from the products of reaction and excess of reagent is effected by settling and filtration, any sulphur in the residue being dissolved or expressed out.  When alkali compounds have been used, or alkaline-earth compounds under pressure, the thioarsenate is removed from the residue in solution and this may be treated with carbon dioxide or acids to deposit yellow arsenic sulphide and evolve sulphuretted hydrogen.  The insoluble residue, after the use of alkaline-earth reagents at ordinary pressure, may be used as a fungicide or an agricultural dressing without removal of the contained sulphur.ALSO:In the purification of sulphur from arsenic and similar impurities by stirring in the molten condition with alkaline-earth compounds, such as a suspension of lime or calcium sulphide in water, the residue, after the separation of the purified sulphur, may be used as a fungicide or as an agricultural p dressing, the contained sulphur not being removed.
