Patent GB-273261-A (GB)
IPC: B01D53/08
Filed: 1927-05-25
Abstract: 273,261.. Silica Gel Corporation, (Assignees of Wagner, F. H.). June 24, 1926, [Convention date]. Gases, separating mixtures of.-Relates to a method of and apparatus for separating a gas or vapour from a mixture of gases or vapours, particularly the separation of the vapour of a volatile liquid, such as sulphur dioxide, ether, alcohol &c., from a mixture with air or other fixed gas, and consists in causing an adsorbent, e.g. silica gel, to travel through a stream of the gaseous mixture in a counter current manner, the adsorbent being admitted into the gas mixture as previously formed suspension' in a non-adsorbable gas such as the mixture after treatment. Means are provided for recovering the adsorbed gas or vapour and reactivating the adsorbent so that it is used continuously. Preferably the gas stream moves upwards while the adsorbent falls in a fine powder through the stream. The gaseous mixture to be treated is fed from an inlet pipe 17 by a blower 15 through an inlet 13 at the base of the adsorbing column 12, while the powdered adsorbent is fed by a current of previously treated gas through an upwardly inclined pipe 37 to the inlet chamber 36, and passes through a telescopically extensible tube 35 into an expansion chamber 10 which is of greater width than the chamber 36. Heat generated by adsorption is removed by a series of cooling sections each consisting of a shell 19, Fig. 3, provided with horizontally arranged cooling-tubes 21 connecting inlet and outlet chambers 23, 22. Flanges 20 are provided so that the units may be bolted together to form the column 12, and cooling medium may be supplied to each column separately or the outlet pipe 25 of one may be connected to the inlet tube 24 of the next. The tubes 21 serve to break up the stream of gas and adsorbent, and this effect may be increased by perforated tubes 46 inserted into the cooling sections and fed with gas by a blower 27 supplied from the pipe 17. From the column 12 the adsorbent passes to a separating chamber 11 and thence, by a conveyer 28, to a reactivating chamber B, the recovered vapours passing off by a delivery pipe 30. The treated gas passes from the exit 18 of the chamber 10 through a separator 38 to remove any remaining adsorbent which passes down the pipe 39 to a conveyer 40. The gas passes through a pipe 41 from which some of it is delivered by a blower 32 to a cooling- tower 33. Into the base of the cooling-tower the adsorbent is fed by the conveyers 31, 40 and is carried by the treated gas through this to the supply pipe 37. Gas not required for the adsorbing operation is drawn through a pipe 42 and a bag separator 44 by a blower 43. Specification 266,586, [Class 55 (ii), Gas manufacture &c.], is referred to.

Title: Polymeric isocyanates and their production
IPC: C08G61/02
Filed: 1954-05-19
Abstract: Polymeric aromatic isocyanates are prepared by contacting a halogeno-alkyl aryl isocyanates of the formula R.CH2.X, wherein R is a phenyl radical containing at least 1 isocyanate group and X is halogen, with a Friedel-Crafts catalyst.  The isocyanate groups may first be wholly or partly converted to carbamic acid halides by passing in gaseous hydrogen halide, in order to speed the reaction and obtain higher molecular weight products.  The isocyanate groups are afterwards reformed by heating, e.g. to 80 DEG  to 120 DEG  C. Co-condensates may be obtained by reacting in the presence of isocyanate-free compounds of the formula R1CH2Cl, wherein R1 is a phenyl or naphthyl radical.  Solvents such as methylene chloride, chloroform and trichloroethylene, may also be present.  The products are brown or dark-red viscous oils or hard resins, having molecular weights from 800 to 2000.  In the examples: (1) FeCl3 (1 gm) is introduced into 1-chloromethyl-2,4-diisocyanetobenzene (208.5 gms.) at room temperature and the temperature rises to 85 DEG  C. with evolution of HCl.  The reaction is completed with heating to 90-100 DEG  C. and removing the HCl by a steam of nitrogen.  The viscous product is soluble in chlorinated hydrocarbons and other lacquer solvents, and reacts with diols and linear polyesters to produce cross-linked polyurethanes; (2) HCl is passed into a mixture of 1-chloromethyl-2,4-and 2,6-diisocyanatobenzene and on cooling FeCl3 is added.  The reaction is completed as in (1); (3) p-chloromethyl-phenyl-isocyanate is reacted using FeCl3; (4) 1-chloromethyl-2,4-diisocyanatobenzene is cocondensed with benzyl chloride using FeCl3; (5) the reaction of Example (2) is repeated in methylene chloride; (6) about 50 per cent of the NCO-groups of 1 - chloromethyl - 2,4 - diisocyanatobenzene are converted to carbamic acid chloride groups and the reaction completed as in (1). Specification 752,931, [Group IV (b)], is referred to.
