DERIVATIVES OF ETHYL ALCOHOL. 61 



very thin liquid, of a disagreeable odor like that of 

 onions; specific gravity, 1.324; boiling point, 158; 

 gives off* fumes in contact with the air, takes fire and 

 burns with a white flame. When air is allowed entrance 

 to it very slowly, it is oxidized, forming triethylstibine 

 oxide (C 2 H 5 ) 3 SbO, a viscid, uncrystalline base, easily 

 soluble in water ; forms with acids crystallizing salts. 

 From the solutions of these salts hydrochloric acid 

 precipitates a chloride (0 2 H 5 ) 3 SbCl 2 , in the form of a 

 colorless, thick liquid. Triethylstibine combines with 

 sulphur, forming triethylstibine sulphide (C 2 H 5 ) 3 SbS, 

 crystals with a silvery lustre. Ethyl iodide combines 

 with triethylstibine at 100, forming 



Stibethylium iodide, (C 2 H 5 ) 4 SbI. Large transpa- 

 rent prisms, easily soluble in alcohol, but slightly 

 soluble in ether. Silver oxide converts it into stib- 

 ethylmm hydroxide (C 2 H 5 ) 4 Sb.OH, a colorless, oleaginous 

 liquid, which conducts itself like the analogous arsenic 

 compound. 



Triethylborine (Borethyl), (C 2 H 5 ) 3 B, is formed by 

 the action of ethyl borate on zinc ethyl. Colorless, 

 very mobile liquid ; specific gravity, 0.6961 ; boiling 

 pointy 95 ; its vapor excites to tears. It combines 

 with ammonia with great avidity. In contact with 

 the air and in oxygen it is oxidized, forming triethyl- 

 borine oxide (C 2 H 5 ) 3 B0 2 , a colorless liquid, boiling at 

 125, which breaks up into alcohol and (0*E?)H*BO a 

 in contact with water. 



Triethylbismuthine, (C 2 IP) 3 Bi, is formed from bis- 

 muth-potassium and ethyl iodide. Heavy, unvolatile 

 liquid, of a very disagreeable odor. It is extracted 

 from the mass by means of ether. It fumes in the air 

 and takes fire spontaneously. It conducts itself like 

 triethylstibine ; its compounds, however, are less stable. 



Zincethyl, (C 2 H 5 ) 2 Zn, is formed by the action of 

 zinc on an ethereal solution of ethyl iodide at 150 

 (if sieved zinc-filings or a small amount of zincethyl
