Cadmium acetate bromide

Rubidium metal alloys with the other alkaU metals, the alkaline-earth metals, antimony, bismuth, gold, and mercury. Rubidium forms double haUde salts with antimony, bismuth, cadmium, cobalt, copper, iron, lead, manganese, mercury, nickel, thorium, and 2iac. These complexes are generally water iasoluble and not hygroscopic. The soluble mbidium compounds are acetate, bromide, carbonate, chloride, chromate, fluoride, formate, hydroxide, iodide. 

Cadmium bromide is prepared by heating cadmium with bromine vapor. Also the compound can be prepared by the treatment of dry cadmium acetate with glacial acetic acid and acetyl bromide. Alternatively, it may be obtained by dissolving cadmium or cadmium oxide in hydrobromic acid and evaporating the solution to dryness under hehum in an inert atmosphere. 

Cadmium acetate is used in the pottery and porcelain industry for producing iridescent effects the borotungstate forms an aqueous solution of high density when concentrated (d = 3.28), useful in die mechanical separation of minerals and in density gradient techniques the bromide, like the zinc salt, is used in photography, process engraving and lithography. 

Cadmium bromide may be prepared by the same procedure from cadmium acetate and acetyl bromide (or HBr gas).

With aliphatic cadmium compounds, however, unexpected results were noted. Dibutylcadmium reacted with tetraacetylglucosyl bromide to give a fifty-seven percent yield of an acetal-like compound, 1,2-(1-... 

It is apparent from the foregoing that a more specific method for the determination of xylan would be desirable. To this end, the determination of xylose, after acid hydrolysis of the polysaccharide material, has been attempted. Xylose may be oxidized to xylonic acid which can be precipitated with cadmium bromide as the double salt, but the precipitation is not quantitative. Xylose forms an insoluble, crystalline di-O-benzylidene dimethyl acetal which permits identification in the presence of other sugars, but the necessity for anhydrous reaction conditions precludes the adaptation of this method to ordinary analysis. AVise and Ratliff prepared this derivative of both d- and L-xylose, as well as analogous derivatives from other aromatic aldehydes, and concluded that, with either the di-O-benzylidene or the di-O-(p-isopropylbenzylidene) dimethyl acetal, an excellent, highly specific, qualitative test was available for d- or n-xylose.

Similar attempted cleavage reactions of the lead-iron derivative with cadmium(II) iodide, copper(II) chloride dihydrate, cobalt(II) chloride hexahydrate, bismuth(III) bromide, and K[Pbl3] failed to give any iron carbonyl derivatives of these metals 198). The black air-sensitive derivative of divalent lead [PbFe(CO)4] has been obtained on treatment of [HFe(CO)4] with basic lead(II) acetate 199).
