68 BUTYL ALCOHOLS. 



point, 115-116. But slightly soluble in water. Yields 

 butyric acid by oxidation. 



Butyl chloride, C 4 H 9 C1. Clear liquid. Boiling 

 point, 77.6; specific gravity, 0.8874 at 20. The 

 bromide, C 4 H 9 Br, boils at 100.4 ; specific gravity, 

 1.2792 at 20. The iodide, C 4 H 9 I, boils at 129.6; 

 specific gravity, 1.6136 at 20. 



Butyl cyanide, C 4 H 9 .CK Liquid, boiling at 140.4, 

 of exceedingly disagreeable odor. Specific gravity, 

 0.8164 at 0. 



Butyl-ethylether, C 4 H 9 .O.C 2 H 5 . Liquid, boiling 

 at 91.7; specific gravity at 20, 0.7512. 



Butylamine, C 4 H 9 .KH 2 . Clear liquid, possessing a 

 strongly arnmoniacal odor, fumes in contact with the 

 air, very hygroscopic. Mixes with water in all propor- 

 tions. Boils at 75.5 ; specific gravity, 0.7553 at 0. 

 "With hydrochloric acid and platinum chloride it yields 

 a double salt, (C 4 H 9 .NH 2 .HCl) 2 PtCl 4 , which crystallizes 

 in gold-colored laminae, but slightly soluble in cold 

 water, more readily in hot water and in alcohol. 



2. Isobutyl alcohol, ^ i CH.CH'.OH. Is often 



contained in fusel-oil, and is obtained from this like 

 propyl alcohol. Colorless liquid of specific gravity 

 0.805. Boiling point, 108-109. Soluble in 10 parts 

 of water, and is precipitated from this solution by 

 soluble salts. By oxidation it is converted into, isobu- 

 tyric acid. 



Isobutyl chloride, C 4 H 9 C1. Colorless" liquid, boil- 

 ing at 64-68. The bromide, C 4 H 9 Br, boils at 92 ; 

 the iodide, C 4 H 9 I, at 121. 



3. Secondary butyl alcohol (butylene hydrate), 



CH 3 .CH 2 .CH.OH.CHA The iodide corresponding to 

 this alcohol is obtained by distilling erythrite with
