Antimony Trichloride, Solution

Antimony(ni) Oxide. 1. Take 10 ml of an antimony trichloride solution acidified with hydrochloric acid and add a sodium carbonate solution up to a weakly alkaline reaction. What is observed Heat the reaction mixture until the carbon dioxide bubbles stop evolving.. Let the precipitate settle, and wash it several times with hot water by decantation. 

Zinc a black precipitate of antimony is produced. If a little of the antimony trichloride solution is poured upon platinum foil and a fragment of metallic zinc is placed on the foil, a black stain of antimony is formed upon the platinum the stain (or deposit) should be dissolved in a little warm dilute nitric acid and hydrogen sulphide passed into the solution after dilution an orange precipitate of antimony trisulphide will be obtained.

Some aromatic hydrocarbons (e.g. perylene) give cation radicals in (neat) antimony trichloride solutions at 75° (Porter et al., 1970 Johnson, 1971). However, the cation radicals are not formed in the absence of oxygen. In fact, molten antimony trichloride can be used as a solvent at 99° for the anodic oxidation of perylene, naphthacene, and other polynuclear aromatics, provided that the electrolyte (e.g. KC1) is highly dissociated (Bauer et al., 1971). When a more covalent electrolyte (e.g. A1C13) is used, the solvent system itself becomes the oxidant [(17) and (18)].

The standard chemical and biological methods of analysis are those accepted by the JnitedStates Pharmacopeia XXIII as well as the ones accepted by the AO AC in 1995 (81—84). The USP method involves saponification of the sample (dry concentrate, premix, powder, capsule, tablet, or aqueous suspension) with aqueous alcohoHc KOH solvent extraction solvent removal chromatographic separation of vitamin D from extraneous ingredients and colormetric deterrnination with antimony trichloride and comparison with a solution of USP cholecalciferol reference standard. 

Antimony trichloride is used as a catalyst for polymerization, hydrocracking and chlorination reactions as a mordant and in the production of other antimony salts. Its solution is used as an analytical reagent for chloral, aromatics and vitamin A. 

The pure sulphide is obtained from its ore. Stibnite is separated from other ores by grinding and flotation. The ore is then heated to 550-600°C in a perforated vessel. The pure molten material is collected and cooled. It is also prepared by passing hydrogen sulfide into a solution of antimony trichloride ... 

Triammino-antimony Trichloride, [Sb(NH3)3]Cl3, is produced when dry ammonia is passed through a solution of antimony trichloride in acetone.2 A mixture of compounds is apparently formed of which the triammine is the chief. It is a white powdery substance which is stable in air but loses ammonia on heating. 

The aluminum chloride is handled, in this case, as an approximately 9% solution in relatively inert molten antimony trichloride the solution has a solidification point of about 170° F. (10). As in the other processes, a small amount of liquid aluminum chloride-hydrogen chloride-hydrocarbon complex is continuously formed. 

The benzobisazole family of rigid-rod polymers is soluble in acidic solvents such as PPA, methanesulfonic acid, chlorosulfonic acid, 100% sulfuric acid and Lewis acid salts such as antimony trichloride and bismuth trichloride. More recently, PBZT has been reported [22] to form liquid crystalline solutions in nitromethane containing aluminum trichloride or gallium trichloride. Since the glass transition temperature of these materials is above their decomposition temperature, they must be processed from solution. 

When all the bromobenzene has been added, there is added slowly through the separatory funnel a solution of 114 g. (0.5 mole) of freshly distilled antimony trichloride (m.p. 67-73°) in 300 cc. of dry ether. The reaction proceeds smoothly and even briskly with the freshly distilled chloride. However, if the latter has not been freshly prepared, gentle warming may be required to start the reaction. When all the antimony trichloride has been added (one to two hours), the mixture is heated on the steam bath for an hour longer. 

This synthesis has been extended to the heavier heterobenzenes. The exchange reaction of 15 with antimony trichloride gave l-chloro-l,4-dihydrostibabenzene 18 as a crystalline solid 10>. On treatment with base, 18 afforded stibabenzene 4. While stibabenzene can be isolated and characterized, it rapidly polymerizes even from dilute solutions at ambient temperature. The reaction of bismuth trichloride and 15 afforded a good yield of crystalline 1 -chloro-1,4-dihydrobi smabenzene 19, which on reaction with base at 0 °C gave only intractable material11). However, bisma-benzene 5 has been detected both spectroscopically 241 and via chemical trapping n). 

A crystalline 2 1 complex (Cl) of antimony trichloride and naphthalene was obtained from a hot petroleum ether solution on cooling. An X-ray analysis (275) revealed an interaction between the antimony atom and the arene n system. The structure consists of layers of antimony trichloride molecules alternating with layers of naphthalene molecules. The coordination sphere around the antimony atom is portrayed in Fig. 16. Two antimony-chlorine distances are equal, while the third is significantly longer. The antimony atom is 3.2 A away from the plane of the naphthalene molecule, thus indicating a weak n interaction. 

If the solution so obtained is distilled, steam and hydrochloric acid pass off at first, later a mixture of hydrochloric acid and antimony trichloride, and finally pure antimony trichloride.

At the starting point of the chromatogram, apply 0.015 mL of the Standard Solution and 0.01 mL of the Sample Solution. Develop the chromatogram in the chromatographic chamber lined with filter paper dipping into the solvent mixture. When the solvent has ascended 10 cm, remove the plate, allow it to dry in air, and spray it with antimony trichloride TS. The blue spot formed is indicative of the presence of retinol. The approximate Rf values of the predominant spots, corresponding to the different forms of retinol, are 0.1 for the alcohol, 0.45 for the acetate, and 0.7 for the palmitate. 

Hydrogen sulphide orange-red precipitate of antimony pentasulphide, Sb2S5, in moderately acid solutions. The precipitate is soluble in ammonium sulphide solution (yielding a thioantimonate) in alkali hydroxide solutions, and is also dissolved by concentrated hydrochloric acid with the formation of antimony trichloride and the separation of sulphur. The thio-salt is decomposed by acids, the pentasulphide being precipitated. 

Preparation.—The main source of rubidium compounds is the residual mother-liquor obtained in the extraction of potassium chloride from carnallite. The solution contains rubidium-carnallite, RbCl,MgCI2, a substance transformed by addition of aluminium sulphate into rubidium-alum, RbAl(S04)8,12H20. Separation from the potassium and caesium salts also present is effected by fractional crystallization of the alum,8 of the chloroplatinate 8 Rb2PtCl8, of rubidium-iron-alum,4 and of the double chloride with stannous chloride5 or with antimony trichloride.6... 

Reagent. Dry some antimony trichloride over phosphorus pentoxide, melt the dried material (m.p. 73 ), and pass dry chlorine gas into the melt until a yellow fuming liquid is obtained. Add this liquid to about 10 times its volume of chloroform, filter the solution into a dark glass-stoppered bottle, and store in a desiccator.
