72 HEXYL ALCOHOLS. 



That portion of the volatile oil of Heradewn gigan- 

 teum, which boils at 201-206, consists partially of 

 hexyl butyrate. The alcohol, prepared from this ether 

 by means of saponification, boils at 156.6. The 

 iodide boils at 179.5. 'f'his alcohol, as well as the 

 preceding one, yields an acid C 6 H 12 2 by oxidation, 

 and is probably the normal alcohol. It is not decided 

 whether these two alcohols are identical or not. 



2. Secondary hexyl alcohol (0-Hexyl alcohol), 

 CH 3 .CH 2 .CH 2 .CH 2 .CH.OH.CH 3 . When mannite is dis- 

 tilled with concentrated hydriodic acid, there results 

 an iodide, C 6 H 13 I, boiling at 167.5. This yields the 

 alcohol when heated with silver oxide and water. 

 A liquid, boiling at 137 ; of specific gravity, 0.8327 

 at 0. Its conduct towards sulphuric acid is similar to 

 that of amylenehydrate. Yields by oxidation carbonic, 

 acetic, and butyric acids ; as an intermediary product, 

 methyl-butylketone. 



The chloride of the same alcohol (C 6 H 13 C1, boiling 

 point, 125-126) appears to be formed together with 

 the chloride of the primary alcohol by the action of 

 chlorine on the hexyl hydride from petroleum. 



In addition to these there are three tertiary hexyl 

 alcohols known : 



3. Dimethylpropylcarbinol, ^ j C.OH.CH 2 . 



CH 2 .CH 3 . From butyryl chloride and zincmethyl like 

 pseudobutyl alcohol. Boiling point, 115. By oxi- 

 dation it yields acetic and propionic acids. 



4. Diethylmethylcarbinol, ciRCH* } - OH - CHS - 

 From acetyl chloride and zincethyl. Boiling point, 

 120. Yields by oxidation only acetic acid.

5. Dimethylpseudopropylcarbinol, 3 C. 



OH.CH -j QTT 3 Is obtained by the action of isobutyryl 

 chloride on zincmethyl. Colorless liquid, that con-
