74 OCTYL ALCOHOLS. 



208 is the acetic ether of this alcohol. By decom- 

 posing this with caustic potassa the alcohol is obtained. 

 Colorless liquid, insoluble in water ; specific gravity, 

 0.83; boiling point, 190-192. 



The chloride, C 8 H 17 C1, boils at 180; the bromide, 

 C 8 H 17 Br, at 198-200 ; the iodide, C 8 H 17 I, at 220-222. 



Secondary octyl alcohol (Methylhexylcarbinol), 

 C 6 H 13 .CH.OILCH 3 . Is formed by the distillation of 

 castor oil with alkaline hydrates, and can be prepared 

 from octyl hydride (obtained from petroleum) in the 

 same way as hexyl alcohol. Oil boiling at 181. 

 Yields by oxidation at first methyl-hexylketone and 

 then acetic and caproic acids. 



The chloride, C 8 H 17 C1, boils at 175. 



Tertiary octyl alcohol (Propyldiethylcarbinol), 



P2TT5 1 



Q 2 J[5 [ C.OH.C 3 H 7 . Prepared from butyryl chloride 



and zincethyl in the same way as pseudobutyl alcohol. 

 A liquid, boiling between 145-155. 



9. Nonyl alcohol, C 9 H 20 0, a liquid, boiling at about 

 200, and 



10. Decatyl alcohol, C 10 H 22 0, a liquid, boiling at 

 210-215, have been prepared from the corresponding 

 hydrocarbons of petroleum in the same way as hexyl 

 alcohol. They have not been subjected to closer 

 study. 



11. Cetyl alcohol, C 16 II 34 0. A compound ether of 

 this alcohol is the principal constituent of spermaceti. 

 By boiling this with an alcoholic solution of potassa 

 the alcohol is obtained. White crystalline mass, fusing 

 at 50, volatile without decomposition. 



12. Ceryl alcohol, C 27 H 56 0. In Chinese wax and in 

 opium wax in the form of ceryl cerotate and palmitate.
