Phosphorus:oxygen ratio

In addition to the loss of the more volatile constituents such as sulfur, phosphorus, chlorine, and oxides of sodium and potassium there was a loss of iron oxides owing to the formation of metallic iron, and also of silica. Silica loss was caused by its reduction to volatile silicon monoxide, which was subsequently reoxidized and removed in the gas stream as silica fume. With coke the silica loss was 5% at a steam oxygen ratio of 1.3, but this increased rapidly at a ratio of about 1.10 vol./vol. to more than 15%. Typical losses of sodium oxide, potassium oxide, and sulfur were 5, 5, and 40% respectively at 1.3 vol./vol., increasing to 40, 40, and 80% at a ratio of 1.10 vol./vol. These materials were deposited in varying degrees in the gas offtake and in the sumps of the waste heat boiler and final cooler. The deposits in the gas offtake were enriched with alkali metal oxides and had a silica concentration of more than 50%. Most of the material was removed in the bottom of the waste heat... 

Miscellaneous Reactions.—The reaction of phosphorus trichloride with toluene in the presence of oxygen is known to yield the hydrocarbon (58) and benzylphosphonic dichloride (59).48 The product ratio is now found to be greatly dependent upon the partial pressure of oxygen,49 and earlier views on the relation between the products have been altered. 

Both Kalckar and the Russians measured the ratio of atoms of phosphorus yielding ATP to the atoms of oxygen utilized (P/O ratio) and found values significantly greater than 1, the figure expected if a phosphate group had been introduced into a cycle intermediate, as in the glycolytic pathway.
