Abstract
WITH the appearance of this number, the volume dealing with the four halogens is complete. The present issue deals at considerable length with com-pounds of iodine with hydrogen, oxygen, nitrogen and other halogens. Very full details are given of the well-known and often quoted equilibrium between hydrogen, iodine and hydrogen iodide, and the effects of ultra-violet radiation, the electric spark, catalysts and a-rays upon the system are all reviewed. Then follow various methods of preparing the gas and the acid solution. On the large scale, both products are generally prepared by the method commonly used in laboratories, namely, the interaction of iodine, phosphorus and water. A fairly recent American technical process is quoted in which hydrogen is allowed to react upon iodine in the presence of suitable solvents, such as water, acetic acid, carbon tetrachloride, toluene or stannic chloride under a pressure of nearly 500 atmospheres.
