HEPTYL ALCOHOLS. OCTYL ALCOHOLS. 73 



geals at 35, forming a white crystalline mass. 

 Boiling point, 112-113 ; specific gravity at 0, 0.8364. 

 Yields by oxidation acetone, and by further oxidation 

 of this, acetic acid. 



7. Heptyl Alcohols ((Enanthyl Alcohols). 

 C 7 H 16 = C 7 II 15 .OH. 



1. Primary heptyl alcohol. Is contained in the 

 fusel-oil from grape skins, and is prepared from heptyl 

 hydride (obtained from petroleum) in the same way as 

 hexyl alcohol. Is also formed by the action of hydro 

 gen in stain nascendi on cenanthylic aldehyde. Color 

 less liquid, insoluble in water, boiling at 164-165. 

 The chloride, C 7 H 15 C1, obtained from heptyl hydride 

 by the action of chlorine, boils at 146-149. 



It^is not positively known whether these alcohols, 

 obtained from different materials, are identical. 



2. Secondary heptyl alcohol, 



CH.OH. Is produced by the action of hydrogen on 

 butyrone. Liquid that boils at 149-150 ; but slightly 

 soluble in water ; soluble in all proportions in alcohol ; 

 specific gravity at 25 = 0.814. The iodide, OH 15 !, 

 boils at^lSO , but not without undergoing partial de 

 composition. 



3. Triethylcarbinol (Tertiary heptyl alcohol),C 7 H 16 

 = C 2 H 5 .C.OH | g^ Is produced by the action of 



propionyl chloride on zincethyl. Colorless liquid, of 

 an odor similar to camphor; boiling point, 140-142 ; 

 specific gravity, 0.8593 at 0. Yields by oxidation 

 acetic and propionic (?) acids. 



8. Octyl Alcohols (Capryl Alcohols). 

 C 8 II 18 = C 8 II 17 .OH. 



Primary octyl alcohol. That portion of the vol 

 atile oil of Heradeum spondylium which boils at 206- 

 7
