FUSEL OIL FROM SUGAR WASTE 



[From Consul (leueral .himcs L. Rodgeis, Havana, 



Inquiry is made regarding the production of fusel oil in Cuba. After careful 

 inquiry it is evident that no attempt is made to save this valuable by-product by the 

 distilleries of Cuba, which run on the large supply of molasses coming from the sugar 

 mills. As far as 1 can ascertain this is more the result of lack of knowledge in the 

 matter of the production of fusel oil rather than any intention to sacrifice value. 



Among the distilling interests to which this matter has been submitted one company 

 is very anxious to open correspondence with a view of securing the technical advice 

 and assistance which would be necessary in developing this new feature of their industry. 



The price of molasses in Cuba fluctuates from year to year, but it can be averaged 

 safely at about 3M> cents per gallon. All the available supply finds a ready market 

 in Cuba, as it is used in local distilleries and is also shipped abroad in large quantities. 

 In 1910 (the latest statistics available) the exportation of molasses from Cuba was 

 in value $1,477,756, of which over 60 per cent went to the United States and very 

 nearly all the remainder to England. 



Roughly estimated, the present-day distillation of alcohol of all grades in Cuba 

 would be about 1,000,000 gallons annually. There are no accurate statistics available. 



Fusel oil is a by-product produced in the distillation of alcohol from various sub- 

 stances, including grain, beet and cane molasses, and wood. Its chief use in the 

 United States is in connection with the manufacture of explosives. It is also used 

 in making artificial fruit essences. The total output of this oil in the United States 

 was 110,792 gallons during 1910, the last year for which figures have been compiled 

 bv the United States internal-revenue officials. — United States Bureau of ^Manufactures.
