Patent GB-767821-A (GB)
Title: Improvements in and relating to ion-exchange resins
Inventor: HALE DOUGLAS KNIGHT
IPC: C08F8/00
Filed: 1953-06-11
Abstract: An insoluble ion-exchange resin derived from a copolymer of an aromatic monovinyl hydrocarbon, e.g. styrene, and an aromatic divinyl hydrocarbon, e.g. divinyl benzene, contains both organic acid groups and basic nitrogen groups attached to the same resin matrix.  The organic acid group is preferably derived from acetic or diacetyl acetic acid.  The resin may be produced by (1) condensing an amine derivative of the copolymer with a halogenated organic acid, e.g. chloracetic acid, or salt thereof to give a product containing imino groups, or (2) condensing such a copolymer containing reactive halogen groups with an acid containing imino groups, e.g. imino-diacetic acid, or with a derivative thereof, e.g. the dinitrile of iminodiacetic acid, followed by hydrolysis to liberate the acid groups, which results in a product containing t-amine groups.  The halogen groups may be introduced into the copolymer as described in Specifications 654,706, 670,348 and 679,850-3, and for use in method (1) a resin containing halo-alkyl groups thus produced may then be aminated by reacting with (a) ammonia, an arylamine, an alkylamine, e.g. methylamine, ethylene diamine or a poly-primary amine, or (b) potassium phthalimide or a monophthalimido derivative of a diprimary amine, such as ethylene diamine, followed by hydrolysing off the phthalic acid structure.  Additional basic nitrogen groups may then be introduced into the aminated copolymer by condensation with ethylene or polyethylene imine.  The products serve either as cation- or anion-exchange resins and when the acidic and basic groups are separated by one or two carbon atoms they will form complexes with particular metallic ions, e.g. those of copper, nickel, cobalt, chromium or manganese.  In examples, the copolymer of styrene and divinyl benzene is produced by heating with benzoyl peroxide catalyst in aqueous suspension using a cellulose derivative as stabilizer.

Title: Improvements in or relating to process and apparatus for production of hydrogen cyanide
IPC: C01C3/04
Filed: 1952-06-27
Abstract: In a system for recovering hydrogen cyanide from an actifier gas leaving a coke oven byproduct gas actification unit, which gases contain cyanide, hydrogen sulphite and other acidic gases, said system having areas such as inspection covers, manholes, pressure relief valves &c., where hard black solid material is deposited steam is led directly to and sweeps through these zones thereby preventing the formation of the solid material which is probably polymeric.  The actifier gas is obtained by washing the coke oven gas with a liquid thereby absorbing HCN and other acidic gases, then desorbing and entraining the HCN in an actifier by the passage of a gas which regenerates the washing liquid.  The HCN in the actifier gases emerging is selectively absorbed in acidic <PICT:0716673/III/1> water in an absorber and rectifier and finally stripped therefrom in a HCN still, and in such a system the absorber, rectifier and still are prone to the deposits mentioned.  In the Figure, actifier gas from a source not shown enters the packed absorber 2 having a lower rectifier section 1 at 24 and passes countercurrent to a stream of acidified water entering at 46, which water selectively absorbs HCN. The charged absorbent passes through the rectifier 1 heated by steam entering at 47, and gives up all other absorbed gases except HCN, and other gases leaving at 3.  The HCN containing water passes through pipe 7 to a reboiler 9, heated by indirect steam, and through pump 90 and pipe 32 to a still 25 where it is heated sufficiently by indirect steam at 40 to drive off the HCN to a condenser 27 to remove water vapour which is returned to the still.  The stripped absorbent after cooling re-enters the absorber 2 at 46.  The dotted line indicates steam fed directly to the places where deposits may form, i.e. packing charge and discharge ports 5 and 60. to a rupture disc safety valve assembly 21 on the absorber reboiler 9 and to the packing port 36 in the still 25.  Specification 612,122 which describes a typical system for recovering HCN from coke oven gas, is referred to.
