I also prepared the lead-salt, which exhibited the properties of lead-pro- 

 pionate; it did not crystallize, but dried up to an amorphous gum- like 

 mass. As by oxidation no other acid besides propionic was found, it 

 follows that the alcoholic liquid could only contain normal propyl alcohol. 

 I tried to isolate this body from the remaining liquid, by adding potas- 

 sium carbonate until it separated into two layers. The upper one was 

 taken off and dried, first over fused potassium carbonate, and afterwards 

 over anhydrous baryta. This liquid, however, proved to be a mixture ; it 

 began to boil at 80° C, and the boiling-point rose slowly to 96° C. By 

 fractionating it could be separated into two portions — a smaller one boiling 

 between 80°-85°, and a larger one boiling above 90°. The portion 

 boiling between 92°-96° gave, by combustion, numbers agreeing with the 

 composition of propyl alcohol. 



0*2238 substance gave 0*4098 carbon dioxide and 0*2675 water.

I have not yet studied the properties of this alcohol, as I hope to 

 obtain it soon in larger quantities. 



The liquid boiling between 80°-85° appears to be an acetal ; it is not 

 acted upon by sodium, and therefore can easily be obtained free from alcohol, 

 by distilling it over this metal. The small quantity was just sufficient for 

 two analyses, the results of which give C 5 H 12 2 as the probable formula. 



O) 0*2500 gave 0*2725 water and 0*5280 carbon dioxide. 



(2) 2755 gave 0*2950 water ; the determination of carbon was lost.

 How this body has been formed I cannot explain. 



As 1 have already mentioned, chloride of propyl forms only a small 

 fraction of the products obtained by subjecting propane to the action of
