* Oxidation of 2-Butylhexane. 
The hydrocarbon was oxidized by allowing it to stand in con- 
tact with an alkaline solution of potassium permanganate at 
room temperature for about 4 weeks. Three equivalents for per- 
manganate were used, enough water being added to make the 
concentration of the permanganate 5 per cent at the beginning of 
the oxidation. Only a small amount of the hydrocarbon was 
oxidized. The unoxidized portion was separated from the aqueous 
layer, the latter acidified and distilled with steam into diluted 
ammonia. This distillate was concentrated to a small volume 
in vacuo and the fatty acid precipitated as the silver salt. 
0.0971 gm. silver salt gave on ignition 0.0531 gm. silver.
