] 74 Mr. Schorlemmcr on the Hydrocarbons [April 6, 



(1) 0-3067 of the acetate from amyl gave 0*8065 carbonic acid and 

 0-3270 water. 



(2) 0'2474 of the acetate from the hydride gave 0-6495 carhonic acid 

 and 0-267 water. Found.

The alcohols C 10 H 22 O were obtained from the acetates by heating them 

 with a concentrated solution of caustic potash, and drying the liquids over 

 chloride of calcium and a little sodium. The alcohol derived from amyl 

 boils between 210-215 ; its specific gravity is 0-8257 at 12. It possesses 

 a pleasant penetrating odour, resembling that of the flowers of Daphne 

 odorata; but also has some resemblance to the smell of octyl-alcohol. 



The alcohol obtained from the hydride has a similar odour, but not quite 

 so pleasant ; it boils also at 210-215, and has at 14 the specific gravity 

 0-8380. The following data give the results of the analysis of the 

 alcohols : 



(1) 0-1846 of the alcohol from amyl gave 0'5120 carbonic acid and 

 0-2305 water. 



(2) 0-1834 of the alcohol from hydride gave 0*5075 carbonic acid and 

 0-2320 water. Found.

The alcohols and acetates were burnt with oxide of copper alone, without 

 a current of oxygen, and this will account for the loss in carbon. 



Unfortunately I obtained these alcohols in small quantity only, and I am, 

 therefore, obliged to postpone for the present the investigation of their 

 derivatives. Both dissolve easily in concentrated sulphuric acid ; but I 

 did not succeed in obtaining either of the sulpho-salts in the crystallized 

 state. I have not yet studied the products of oxidation of these alcohols. 



From the above researches I conclude that no difference exists in the 

 chemical behaviour of the radicals and of the hydrides ; the difference 

 which has been observed in the physical properties, as in the boiling- 

 points, also diminishes the better and the more closely these hydrocarbons 

 are studied. There are, however, differences in the specific gravities which 

 cannot be overlooked. The radicals as well as their derivatives have a 

 lower specific gravity than the corresponding hydrocarbons from petroleum 

 and their derivatives. It is, however, a well-established fact that it is im-
