Perfluoroalkyl iodides

Perfluoroalkyl iodides. (Daikin Kogyo Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58192838 A2 10 Nov 1983 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C07C019-07; C07C017-04. ICA: B01J027-14. APPLICATION: JP 82-73933 1 May 1982. DOCUMENT TYPE: Patent CA Section: 23 (Aliphatic Compounds) CF3CF2I and (CF3)2CFI were prepd. by reaction of I2 and IF5 with C2F4 and CF3CF:CF2, resp., in the presence of PCl5 or P2O5, where SF6 or CF3CF2I was optionally used as a diluent. Thus, 0.573 mol C2F4 was introduced to 0.198 mol I2, 0.0986 mol IF5, and 2.05 g PCl5 in an autoclave in the absence of air with stirring at 40-50°/5-7 kg/cm2 gage to give 95.5% (based on IF5) CF3CF2I, vs.In this experiment, several chemicals are used like 7783-66-6 and 116-15-4 38.0% without PCl5. .

Carbon tetrafluoride

Carbon tetrafluoride. (Kanto Denka Kogyo Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58203924 A2 28 Nov 1983 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C07C019-08; C07C017-00. APPLICATION: JP 82-87812 24 May 1982. DOCUMENT TYPE: Patent CA Section: 23 (Aliphatic Compounds) CF4 was prepd. by reaction of C with F gas during which other halogens and/or halogen fluorides were added. Thus, CF4 was introduced into 15 kg powd. coke at 12 m2/h at 350° for 5 min, followed by 7 kg/h IF5, 16.5 m2/h F, and 5 kg/h powd. coke at 350°, and the mixt. cooled to -135 to -140° to give 36.5 kg/h CF4 of 99.999% purity.Except for chemicals metioned above, 7783-66-6 and 75-73-0 are also used. .
