Publisher's Synopsis
Excerpt from Toluol Recovery
Previous to the declaration of war, in 1914, the production of toluol in the United States probably did not exceed 500 000 to 7 50 000 gallons per year. Most of this toluol came from coal-tar distillation, but smaller amounts were prepared by refining the light oils which were removed from coke-oven gas in' a few plants. At once after beginning hostilities the demand for toluol greatly increased, and it was evident that the common sources of this material would not meet the new commercial demands. As a consequence a large increase in the recovery of toluol from coke oven gas immediately followed, and more recently the recovery of this constituent from city-gas supplies made by the coal-gas, water-gas, and oil-gas processes has also resulted.
T 0 give an approximate idea of the magnitude of the industry thus developed, one need only compare the small output of pure toluol in 1912 and 1913 when it was approximately. 500 000 gallons with the probable output for the current year during which period it is hoped that the output will exceed 20 000 000 gallons. Practically all of the increase has been possible because of the recovery of toluol from coke-oven gas and city gas supplies.
