Von Oefele on a new Class of Sulphur Compounds, 529 



by the analysis of the acid or of the salts, the ether was made, 

 and thus the formula of the acid was found to be C 14 H 10 4 . 

 It contains hence four atoms of hydrogen more than benzoic acid ; 

 and it forms an intermediate member between the acids which 

 correspond, as regards carbon, in the aromatic and fatty acid 

 series : — 



Benzoic acid . . . . C 14 H 6 O 4 

 Intermediate acid . . . C 14 rT° O 4 

 (Enanthylic acid . . . C l4 H 14 4 



Herrmann calls this acid Benzoleic acid; it is distinguished 

 from the fatty acids only by greater specific gravity. 



When monosulphide of ethyle and iodide of ethyle are heated 

 together under suitable conditions, Von Oefele* has found that 

 they combine and form a compound crystallizing in small laminae 

 which contains the elements of one atom of sulphide of ethyle 

 and one atom of iodide of ethyle. Its chemical deportment leads 

 to the view that it is the iodide of a radical consisting of three 



atoms of ethyle and two of sulphur, C 4 H 5 ^S 2 , which Oefele 



C 4 H*J 

 calls Triethylsulfine . The body can also be obtained by distilling 

 a mixture of alcoholic solution of monosulphide of potassium with 

 iodide of ethyle. 



When the aqueous solution of the iodide is treated with nitrate 

 of silver, iodide of silver is at once precipitated, and the solution 

 contains nitrate of triethylsulfine ; or if it is treated with freshly 

 precipitated oxide of silver, iodide of silver is obtained with hy- 



C 4 H 5 ] 

 drated oxide of triethylsulfine, C 4 H 5 I S 2 0, HO. The solution 



C 4 H 5 J 

 filtered off from the iodide of silver has a strongly alkaline reac- 

 tion, readily attracts carbonic acid, precipitates solutions of the 

 metals just as does potash, and, when evaporated in the exsiccator 

 or in a vacuum, yields a crystalline body. It so readily attracts 

 moisture that an analysis could not be made. Its salts are ob- 

 tained by neutralization with the corresponding acid ; they 

 are difficult to crystallize, and are very deliquescent. A plati- 

 num-salt, however, was obtained, in splendid dark reddish- 

 yellow prisms, which had the composition 



C 4 H 3 "1 



C 4 H 5 ^S 2 Cl + PtCl 2 . 



C 4 H 5 J
