Title: Process for preparing fluorinated perhalo compounds
IPC: C07C51/60
Filed: 1963-07-24
Abstract: An activated anhydrous chromium (III) oxide is produced by dehydrating, at 400 DEG  to 600 DEG  C. in an inert atmosphere, the gel obtained by reducing chromium trioxide in aqueous solution with, for example, ethanol; the commercial pigment Guignet's Green (C2O3.2H2O); or the material obtained by precipitating water-soluble chromium salts from aqueous solution with alkaline hydroxides.  The oxide is employed as a catalyst in the fluorination of perhalo compounds (see Division C2). Specifications 686,678, 720,091, 720,118, 794,075 and U.S.A. Specifications 2,271,356, and 2,807,646 are referred to.ALSO:Perhalo compounds, wherein at least one of the halogen atoms is fluorine, are produced by passing a vapour mixture of a perhaloacetone, a perhaloacetonitrile or a perhaloacetylhalide, in which perhalo reactant the halogens are chlorine or fluorine, at least one of the hydrogen atoms being chlorine, and at least one mole for each mole of the perhalo reactant of anhydrous hydrogen fluoride over a catalyst which consists essentially of an activated anhydrous chromium (III) oxide (see Division C1) at 200 DEG  to 500 DEG C. such that the principal reaction is the substitution of fluorine for at least one of the chlorine atoms in the perhalo reactant.  The hydrogen fluoride is usually employed in excess of the stoichiometric amount required since the degree of fluorination is primarily dependent upon the reaction temperature and flow rates. The perhalo products are separated from excess hydrogen fluoride and the hydrogen chloride produced by distillation but the perhaloacetone products must then be recovered from hydrogen fluoride complexes by passage over activated sodium fluoride. Perhalofluoacetic acid may be obtained from the perhalo products, e.g. by hydrolysis of the perhaloacetylfluoride.  Specifications 686,678, 720,091, 720,118, 794,075 and U.S.A.  Specifications 2,271,356, 2,807,646 are referred to.

Two sliver cans, 1 are mounted on a base 3 containing the mechanism for transferring the coiler head 11 by partial rotation of a tube 7 that surrounds a shaft 15 driven from calender roller 17. At the lower end of the shaft 15 is fixed a sprocket 23, Fig. 3, connected by a chain 24 to a compound rotatable member including a chain sprocket 25 and a pinion 27 that drives, through a reduction gear train, a worm wheel 57. The compound member is rotatable on a stud 29 that is itself rotatable and to which is keyed a sprocket 33 meshing with a crank gear 35 adapted to swing the coiler head by means of a lever 13 and the tube 7. A clutch, normally held in disengagement by a rod 65, is allowed to engage when a pin 63 on the worm wheel 57 moves a projection 77. In consequence of this engagement, sprocket 33 is rotated and continues to rotate until the clutch is again disengaged by a movement initiated by a projection 75 fixed to the sprocket 33.
