4-Butyloctylic Acid. 
The method used for the preparation of this acid was exactly 
analogous to that described for the preparation of 2-butylhexylic. 
acid. The boiling point is 173-174° at 12 mm. (corrected). The 
specific gravity is 0.901. 
0.1034 gm. substance gave 0.2736 gm. CO, and 0.1108 gm. H,0O. 
Calculated for Found: 
Ethyl 4-Butyloctylate. 
In the preparation of this substance 36 gm. of 4-butyloctylic 
acid were boiled for 6 hours with four molecules of absolute alco- 
hol and a few drops of sulfuric acid. The refractionated product 
weighed 32 gm. It boils at 139° at 10 mm. (corrected). 
0.1000 gm. substance gave 0.2692 gm. CO, and 0.1104 gm. H,0. 
Calculated for Found: 
4-Butyloctyl Alcohol. 
28 gm. of the above ester upon reduction yielded 14 gm. of 
alcohol. The boiling point is 189° at 15mm. Its specific gravity 
is 0.841. 
0.1266 gm. substance gave 0.3584 gm. CO» and 0.1266 gm. H,0.

4-Butyloctyl Iodide. 
This iodide was prepared by boiling a mixture of 10 gm. of the 
corresponding alcohol with four molecules of constant boiling 
hydriodic acid. The yield of iodide was 14 gm. It boils at 143° 
at 8mm. Specific gravity, 1.194.
