Trifluoramine oxide ONF3 which is a colourless gas of melting-point about - 161.5 DEG C. and boiling-point about - 89 DEG C. is prepared by reacting difluoramine with ClF3 and an oxygenated halogen compound, for example ClO2, FClO2 or FClO3. The reactants are first condensed at ...
If the operation is performed in a platinum tube, a large quantity of fused fluoride remains in the tube. The tetrafluoride of platinum, PtF4, formed upon the wires, consists either of fused masses of a deep red colour, or of small buff-coloured crystals resembling anhydrous platinum chloride...
In particular, during the reaction between the fluorine-doped titanium dioxide particles and the fused lithium, it can be noted that the particles of oxide change colour, while maintaining the appearance of a powder. The evolution of the reaction was monitored by means of infrared (IR) ...
passed (1) for half an hour into a three per cent solution of crepe rubber in carbon tetrachloride and (5) for 2 to 3 hours into a solution of chlorinated rubber in p carbon tetrachloride to give a fluorinated and chlorinated rubber of improved heat stability; colour and light transmission...
the former is a heavy colourless liquid of low volatility (vapour pressure 2-3 mm. at 0°), while the monoiodido is a liquid of boiling point 45.8° and melting point-56.5°, which resembles methyl iodide in appearance.doi:10.1038/144328a0MADDOCK, A. G...
