Antimony phosphides

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. 

SbP, antimony phosphide, is white and metallic-, obtained from the reaction between phosphorus and liquefied antimony. 

The metal combines with sulfur and phosphorous on heating, forming the sulfide and phosphide salts, respectively. Metalloid elements, such as arsenic, antimony, selenium and tellurium also combine with indium at elevated temperatures, forming their respective binary salts. 

Reactions with phosphorus, arsenic and antimony form phosphide, arsenide, and antimonide of potassium, respectively ... 

The heat sensitivity (above) may explain the explosions which occur on contact of many readily oxidisable materials with this powerful oxidant. Such materials include ammonia, potassium arsenic, antimony sulfur, charcoal (adsorptive heating may also contribute) calcium phosphide, phosphine, phosphorus hydrogen sulfide, antimony sulfide, barium sulfide, mercury sulfide and tin sulfide [1], Various organic materials (paper, cork, rubber, turpentine, etc.) behave similarly [2]. Mixtures with hydrogen detonate on ignition [1]. 

Phosphorus(III) fluoride can be prepared by the reaction of antimony (III) fluoride with phosphorus (III) chloride, using antimony (V) chloride as a catalyst,1 or by heating copper phosphide with lead fluoride.2 The procedure described here involves the reaction of arsenic(III) fluoride with phosphorus (III) chloride, using antimony(Y) chloride as a catalyst.3,4... 

Antimony reacted in a similar manner.3 The metals, even the noble metals, are converted into chlorides, but at higher temperatures phosphides may be formed.
