Show Production of Toluol Aided by New Formulas Toluol, basis of TNT, which is trinitrotoluol, and other chemicals important in preparing for American Ameri-can defense, will be aided with new formulas announced at a meeting of the American Institute of Mining and Metallurgical Engineers in New York. They were developed by Dr. H. H. Lowry, director of the Coal Research laboratory of the Carnegie Institute of Technology, with the assistance as-sistance of H. G. Landau and Leah L. Naugle. These formulas make it possible to determine accurately in advance the properties and amounts of coke and by-products obtained from the carbonization of coal. The chief byproducts by-products are tar, gas, ammonium sulphate and light oiL The latter is the raw material from which toluol is obtained. In addition to giving scientific control, con-trol, which assures more accurate planning in the production of the coking by-products. Dr. Lowry's work also makes possible greatly increased in-creased economy, by eliminating expensive ex-pensive oven tests. One steel company com-pany alone, he stated, has been able to save many thousands of dollars in the single item of eliminating the sulphur analysis of coke. Carrying Dr. Lowry's work a step further, M. A. Mayers and H. G. Landau, also of Carnegie Tech's Coal Research laboratory, announced an-nounced a method for controlling the properties of pig iron and the economy econo-my of its production in blast furnace fur-nace operation. |
