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. Access through your institution Buy or subscribe This is a preview of subscription content, access via your institution ACCESS OPTIONS
