Abstract
1,160,539. Iodine pentafluoride. ALLIED CHEMICAL CORP. 8 Feb., 1967 [8 Feb., 1966], No. 5983/67. Addition to 1,060,708. Heading C1A. Iodine pentafluoride is prepared by contacting, in a reaction zone of a first stage, fluorine with a solution of iodine in iodine pentafluoride, directing at least part of this pentafluoride to a holding zone of the first stage wherein iodine is dissolved in the pentafluoride, and returning this solution to the reaction zone, and directing from the first stage to a second stage iodine pentafluoride containing unchanged iodine, and contacting in a reaction zone of the second stage the iodine pentafluoride with fluorine to remove iodine therefrom, and withdrawing at least part of the pentafluoride from the second stage as product. The temperatures in the reaction zones are preferably in the range of 10‹ to 98‹ C. The solution of iodine in iodine pentafluoride, used in the reaction zone of the first stage, should contain 0À1 to 5% by weight of iodine. The iodine pentafluoride directed from the first to the second stage, may be withdrawn from the reaction zone or the holding zone of the first stage. A suitable arrangement of apparatus for carrying out the preparation, is illustrated in the figure, the arrangement comprising a reaction vessel 25, hold tank 26, second reaction vessel 33 and second hold tank 32.
