Arsenic tribromide trichloride

Arsenic tribromide (arsenic(III) bromide), AsBr, is similar to the trichloride. The dielectric constant at 35°C is 8.33. The compound is usually made by treating arsenic with a solution of bromine in carbon disulfide.

Similarly, arsenic tribromide AsBrs forms when the trioxide reacts with bromine vapors. Reaction with concentrated HCI under heating produces arsenic trichloride.

The halides, GaQs, AlBrs, A1C13, and FeCl3, very probably also exist in dimeric form. With these halides, however, the complexation reaction with the azide is the fast step so that no square-root term is found in the kinetic equation. Arsenic trichloride, arsenic tribromide, phosphorus trichloride, and phosphorus pentachloride were without effect on the rate of decomposition of benzoyl azide. Finally, the authors have observed that the catalytic influence of boron tribromide was much higher than all the other halides. Its rate constant was estimated to be about 18 times larger than that for gallium chloride. 

Arsenic Trifluoride, AsF3, is formed when fluorine reacts with arsenic trichloride 1 or with the arsenides of the alkali or alkaline earth metals 2 by the action of anhydrous hydrofluoric acid or of acid fluorides on arsenious oxide 3 by the action of certain metallic fluorides, for example silver or lead fluoride on arsenic trichloride,4 or of ammonium fluoride on arsenic tribromide B and by the action of iodine pentafluoride on arsenic.6...

Concentrated hydrochloric acid also dissolves the trichloride, about 100 g. of the latter dissolving in 1 litre of acid at 100° C.7 Dissolution in hydriodic acid is accompanied by evolution of heat and the triiodide is formed.8 Ethyl iodide reacts similarly.9 Double decomposition reactions occur w hen arsenic trichloride is heated with phosphorus triiodide, stannic iodide or germanium iodide, the reactions being complete.10 Similarly, potassium iodide heated with arsenic trichloride in a sealed tube at 210° C., and potassium bromide at 180° to 200° C., form respectively arsenic triiodide and tribromide.11 Stannous chloride, added to the solution in hydrochloric acid, causes reduction to arsenic (see p. 29). Arsenic trichloride may be completely separated from germanium chloride by extraction with concentrated hydrochloric acid.12 Ammonium, sodium and cobaltic chlorides react with arsenic trichloride to form additive compounds with magnesium, zinc and chromic chlorides there is no reaction.13... 

Phosphine yields a copper-coloured precipitate, possibly an arsenide of phosphorus.6 Phosphorus trichloride causes reduction to arsenic,7 as also do the tribromide and triiodide, though less readily. Hypophos-phorous acid causes a similar reduction to arsenic 8 in hydrochloric acid solution the velocity of the reaction at various concentrations corresponds with that of a reaction of the second order and may be expressed by 9... 

Arsenic Amide, As(NH2)3, is formed by the action of ammonia on arsenic trichloride, tribromide or triiodide at -35° to —40° C., the ammonium halide being removed from the residue by washing with liquid ammonia, in which the amide is insoluble.3 It is a greyish-white powder, stable in dry air below 0° C., but above this temperature it begins to decompose, yielding the imide and, at higher temperatures, the nitride. It may be kept at ordinary temperatures in an atmosphere of ammonia without decomposition. Water readily converts it into arsenious oxide and ammonia. 

He found that with ordinary commercial red phosphorus with 98 per cent, phosphorus, there dissolved 0-056 and 0-108 per cent, of phosphorus in respectively 10 and 42 hrs., and with a finely-divided sample 0-092 and 0-116 percent, phosphorus in 10 and 20 hrs. respectively. R. Schenck found that 100 grms. of phosphorus tribromide dissolved 0-2601 grm. of scarlet phosphorus at 172°, and 0-3634 grm. at 184°. E. Baudrimont showed that yellow phosphorus does not attack phosphoryl bromide at the b.p. L. Rosenstein found that soln. of arsenates, and arsenic, antimony, or bismuth salts are not reduced by boiling with red phosphorus but W. Finkelstein found that a nitrobenzene soln. of arsenic trichloride is reduced by yellow phosphorus and arsenic is deposited. 0. Ruff observed that phosphorus reacts with antimony trichloride in the presence of a little aluminium chloride. F. E. Brown and J. E. Snyder observed that vanadium oxytrichloride is without action on red or white phosphorus. 

B. Pelletier23 obtained an antimony phosphide by the action of molten antimony on metaphosphoric acid with or without admixed carbon. B. Pelletier, and G. Landgrebe obtained a phosphide by the action of phosphorus on molten antimony, although W. Ramsay and R. W. E. Mclvor could obtain a product with only 1546 per cent, by direct action. The last-named prepared antimony monophosphide, SbP, by the action of phosphorus on a soln. of antimony tribromide in carbon disulphide. M. Ragg could not prepare the monophosphide by this process, nor by the action of phosphine on tartar emetic, or antimony trichloride. The phosphide prepared by the fusion processes is a brittle, white mass with a crystalline fracture the precipitated product is a red powder insoluble in carbon disulphide, ether, and benzene. O. Ruff found that phosphorus reacts with antimony chloride in the presence of aluminium chloride—vide supra, arsenic oxyphosphide.
