MABERY AND QUAYLE. — CANADIAN PETROLEUM. 103 



and odor, and with no reaction for sulphuric acid. While the analytical 

 values obtained indicated that the hesyl compound was contaminated 

 with a higher homologue, it is evident that bexyl thiophane was the prin- 

 cipal constituent. 



Tbe values given by analysis were as follows : 



C, 49.39 ; H, 8.47 ; S, 19.02. Required for C 6 H 12 S0 2 : C, 48.64; H, 

 8.11; S, 21. G2. 



Heptyl Thiophane Sdlphone, C 7 H 14 S0 2 . 



The oxidation of heptyl thiophane was conducted as described above. 

 After neutralizing with sodium carbouate and evaporating to dryness, 

 the residue was extracted with anhydrous ether. No sulphuric acid 

 was formed by the oxidation. The following results were obtained by 

 analysis of this product : 



I. 0.1992 gram of the substance gave 0.3801 gram C0 2 , and 0.1531 

 gram H 2 0. 

 II. 0.1628 gram of the substance gave 0.2279 gram BaSO^.

This sul phone formed a very thick heavy oil. Its specific gravity was 

 found to be 1.1138 at 20°. 



Octyl Thiophane Sulphone, C 8 H 16 S0 2 . 



50 grams of the fraction 87°-89° identified as octyl thiophane was 

 oxidized carefully at freezing temperature. After dissolving the man- 

 ganic oxide, and distilling with steam, 36 grams of a heavy oil separated 

 with no formation of sulphuric acid. After neutralizing with sodium 

 carbonate, evaporating to dryness, and extracting with ether, this oil gave 

 as its specific gravity at 20°, 1.1142. Its composition was shown by 

 analysis. 



I. 0.1697 grams of the substance gave 0.3385 gram C0 2 , and 0.13G8 

 gram H 2 0. 

 II. 0.2038 gram of the substance gave 0.2702 gram BaS0 4 .
