Filed: 1923-12-20
Abstract: 208,713. Aluminum Co. of America, (Assignees of Hoopes, W., Frary, F. C., and Edwards, J. D.). Dec. 21, 1922, [Convention date]. Drawings to Specification. Aluminium, obtaining. - In obtaining pure aluminium from an alloy using a fused electrolyte, the latter is compounded so as to have a higher density than aluminium and a selective action in dissolving aluminum from the alloy. The density should be between 2.4 and 3.1 gms. per cm. at a working temperature of 1000‹ C. The electrolyte should be molten at 950‹ C. In a cell for carrying out the process the alloy, electrolyte and aluminium form successive layers with the aluminium at the top. The electrolyte should not contain more than 7 per cent of alumina but should be capable of dissolving a considerable amount of alumina if this is formed during the process. A suitable composition consists of aluminium and sodium fluorides together with between 20 and 60 per cent of fluoride of barium or strontium. Fluorides of alkaline-earth metals of lower atomic weight should not be present to more than 2 per cent. Chlorides and other compounds except oxide should not be present. A preferred composition is aluminium fluoride 30 to 38 per cent, sodium fluoride 25 to 30 per cent and barium fluoride 30 to 38 per cent. The sodium and aluminium fluorides may be supplied in part by cryolite. Addition of further sodium fluoride lowers the resistance but couses the liberation of sodium vapour at the cathode which attacks the carbon connections. An electric furnace for carrying out the process is similar to that described in Specification 208,715.
Patent GB-790049-A (GB)
Title: Improvements in cation-exchange resins
Inventor: KRESSMAN THEODORE ROGER ERNEST
IPC: B01J39/18
Filed: 1954-11-04
Abstract: Cation-exchange resins consist of cross-linked phenol-aldehyde resins containing alkylene sulphonic groups and acetic acid groups.  They are prepared by reacting mono-, di- or trichloracetic acid with a cross-linked phenolaldehyde resin containing phenolic hydroxy groups and alkylene sulphonic groups under alkaline conditions.  The alkaline conditions are preferably produced by caustic alkali in excess.  Other bases such as sodium carbonate, ammonia and pyridine may be used.  Both the chloracetic acid and the sulphonic groups are preferably neutralized before the reaction, the latter groups being neutralized with metallic cations.  The cross-linked resins may be prepared by condensing a phenol alkylene sulphonic acid, phenol and an aldehyde such as formaldehyde or a polymer thereof.  Instead of a phenol alkylene sulphonic acid, the acids of catechol, hydroquinone or a cresol may be used; and hydroquinone, catechol, resorcinol, pyrogallol, tannins or m-hydroxy phenoxy acetic acid may be used instead of the phenol.  Alternatively, the cross-linked resins may be made by condensing a phenol with formaldehyde and sodium bisulphite in aqueous solution.  The resin is preferably ground to the desired size before treatment.  The examples describe the preparation of ion-exchangers from monochloracetic and resins prepared from (1) phenol, formaldehyde and sodium bisulphite, (2) resorcinol methylene sulphonic acid, cross-linked with phenol; (3) phenol methylene sulphonic acid, cross-linked with quebrancho tannin; and (4) resorcinol methylene sulphonic acid, cross-linked with m-hydroxyphenoxyacetic acid and phenol.  Specifications 588,380, [Group IV], and 613,139 are referred to.
