Abstract
A Whole number of Industrial and Engineering Chemistry (39, 236–435; March 1947) is devoted to the chemistry of fluorine and its compounds. The production of fluorine on the industrial scale and its storage and utilization are fully described. The common electrolytes are fused acid potassium fluorides with carbon anodes, and up to 2,000 amperes were used in the electrolysing currents. An anode current efficiency of about 95 per cent was attained. Small laboratory units are also dealt with. The gas can be piped in steel or copper, and compressed up to 400 lb./in.2 in nickel and steel cylinders. Purification reached 98 per cent minimum. Fluorination of hydrocarbons formed numerous products up to C18F30, and in this work much use was made of cobalt trifluoride, CoF3, and silver difluoride, AgF2, and reactions in liquid hydrogen fluoride. A novelty is the fluorine-hydrogen blowpipe, used for welding metals. The papers represent a notable advance in fluorine chemistry.
