HEPTYL ALCOHOLS. OCTYL ALCOHOLS. 73 



steals 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 (CEnanthyl Alcohols). 

 C 7 H 16 = C 7 H 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 statu 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. 



OTT3 OTT 2 OTT^ ) 



2. Secondary heptyl alcohol, CH 3 CH 2 CH 2 [ 

 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, C 7 H 15 I, 

 boils at 180, but not without undergoing partial de- 

 composition. 



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



( P2TJ5 



= C 2 H 5 .C.OH j ^ 5 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 H 18 = C 8 II 17 .01I. 



Primary octyl alcohol. That portion of the vol- 

 atile oil of Heracleum spondylium which boils at 206-
