QUATDECYL THIOPHANE. 



Fraction 266°-268° (At. Pres.), C 14 H 28 S. 



This sulphur oil was separated from the distillate 160°-170°, fourth 

 distillation, 50 turn. After the second precipitation and decomposition 

 by hydric sulphide, 400 grams of the sludge distillate gave 75 c.c. of 

 a yellow oil that collected for the greater part at 168°-170°, 50 mm., 

 after extended fractioning. It collected at 266°-268° under 750 mm., 

 and gave percentages by analysis required for the formula C 14 H 28 S. Its 

 specific gravity at 20° was found to be 0.9208. 



I. 0.1859 gram of the oil gave 0.5010 gram CO,,and 0.2109 gram H 2 0. 

 II. 0.2290 gram of the oil gave 0.2336 gram BaS0 4 . 



Found.

Sexdecyl Thiophane. 



Fraction 283°-285° (At. Pres.), C 1I5 H 32 S. 



From 400 c.c. of the first vacuum distillate 170°-180°, 50 mm., after 

 the second precipitation with mercuric chloride and long-continued dis- 

 tillation, 28.5 grams of the sulphur oil collected at 184°-186°, which dis- 

 tilled with some decomposition at 283°-285°, under 750 mm. Analysis 

 gave values required for the formula C 1C H 32 S. Its specific gravity was 

 found to be 0.9222. 



I. 0.2 1 48 gram of the oil gave 0.5934 gram C0 2 , and 0.2380 gram H 2 0. 

 II. 0.1850 gram of the oil gave 0.1683 gram BaS0 4 .

Octodectl Thiophane. 



Fraction 290°-295° (At. Pres.), C 18 H 36 S. 



From 350 grams of the vacuum distillate 190°-210°, 50 mm., alco- 

 holic mercuric chloride gave a very thick viscous precipitate, from which
