DENATURED ALCOHOL. 



There are at present two general formulas for denatured alcohol 

 in use, either one of which may be used by any manufacturer, who 

 can use denatured alcohol. 



The first and most common one is made up as follows : 



Formula No. i. 



Ethyl Alcohol lOO gallons. 



Methyl " lo " 



Benzme 72 



Where such a formula as this is required in an aqueous solution 

 the benzine is of course thrown out, giving the solution a milky ap- 

 pearance. In this case the other general formula may be used. 



Formula No. 2. 



Ethyl Alcohol 100 gallons. 



Methyl " 2 " 



Pyridine Bases /^ " 



Whenever generally denatured alcohol is ordered Formula No. i 

 will be shipped unless Formula No. 2 is specially ordered. 



In addition to these two general formulas for denatured alcohol 

 a number of special formulas have been authorized to be used in the 

 manufacture of certain classes of goods. In order to buy these 

 specially denatured alcohols it is necessary, of course, to obtain a 

 permit first from your Collector of Internal Revenue, a simple permit 

 to use denatured alcohol will not suffice. Some of the special formulas 

 are as follows : 



Formula No. 3. 



For the manufacture of celluloid, pyralin and similar products. 



Ethyl Alcohol 100 gallons.
