Ammonium alum sulfate

The word alum is derived from the Latin alumen, which was appHed to several astringent substances, most of which contained aluminum sulfate (20). Unfortunately, the term alum is now used for several different materials. Papermakers alum or simply alum refers to commercial aluminum sulfate. Common alum or ordinary alum usually refers to potash alum which can be written in the form K SO Al2(SO 24H20, or it can refer to ammonium alum, ammonium aluminum sulfate. The term is also appHed to a whole series of crystallised double sulfates [M(l)M (lII)(SO 2 12H20] having the same crystal stmcture as the common alums, in which sodium and other univalent metals may replace the potassium or ammonium, and other metals may replace the alurninum. Even the sulfate radical may be replaced, by selenate, for example. Some examples of alums are cesium alum [7784-17-OJ,... [Pg.176]

Aloton Also called Buchner. A process proposed for extracting aluminum from clay. Calcined clay is leached with ammonium hydrogen sulfate solution under pressure, and ammonium alum is crystallized from the liquor. Invented by M. Buchner in Hanover-Kleefeld in 1921 piloted in Germany in the 1920s and in Oregon in 1944. It was never commercialized, but provided the basis for the Nuvalon process which was. [Pg.18]

The only simple sulfates of vanadium are formed in the oxidation states -1-3 and -1-2. Vanadium(III) sulfate can be crystallized as a hydrate from aqueous solution, and is strongly reducing. It gives rise to a series of alums of the type M V(S04)2-12H20, which have been shown to contain the [V(H206)] + ion. The ammonium alum, (NH4)V(S04)2 12H20, is obtained as air-stable blue violet crystals by electrolytic reduction of NH4[V03] in sulfuric acid.b ... [Pg.5027]
