Reilly & 1 FiCKiNBOTTOM — Concentration of Alcoholic Liquors. 247 



The following gives a typical example, showing the yields obtained : — 



From 150 grams of Ji-butyl alcohol by oxidation the product had the 

 following composition : — 



?i-Butyl alcoliol . . 17'5 grams. 



7i-Butyl-?i-butyrate . . 109'4 „ 



High boiling-point fraction . 3'0 „ 



?i-Butyrie acid . . . 8'0 „ 



The amount of ester obtained is approximately 75 per cent, of the 

 theoretical yield calculated on the alcohol taken. 



The ester was identified by hydrolysis yielding 7i-butyric acid and ?i-butyl 

 alcohol. The boiling point of the ester is 16677761 mm. 



The authors wish to state that they are much indebted to both Professor 

 Sydney Young, f.k.s., and Dr. F. E. Hackett for many suggestions and useful 

 criticism. They also take this opportunity of expressing their thanks to 

 Captain Desborough for his interest in this work, and for securing permission 

 for publication.
