BENZOL PEODUCTION. 



Before the European war the demand in the United States for 

 benzol and toluol products was so small and the price so low that 

 but one company sought to recover them on a large scale. Late 

 in 1914 the price of benzol, and particularly toluol, rose to such 

 a point that many other companies began to build plants to re- 

 cover these oils, and by the end of 1915 there were 19 new plants 

 for benzol recovery in operation and others in course of 

 erection. 



Reports indicate that the output of benzol and other light oils 

 in 1915 amounted to 13,942,763 gallons. In the 6.620,093 gallons 

 of oils refined at the place of recovery, there were 4,833,939 

 gallons of 1(X) per cent benzol, 1,315,727 gallons of toluol, and 

 470,425 gallons of solvent naphtha. 



The annual capacity of the benzol recovery plants now in 

 operation is estimated at over 20,000,000 gallons, and with the 

 completion of plants now building will probably exceed 22,000,000 

 gallons. The value of these products is indicated by the price 

 currently reported during the year, Benzol, normally selling for 

 20 cents or less a gallon, in September brought as high as $1.25 

 for immediate shipment and 65 cents on contract ; toluol, with a 

 normal price of 25 cents, was sold for as much as $6 a gallon for 

 immediate delivery and was contracted for at $4.25 per gallon.
