Potassium fluoride phosgene

Chlorodifluoroamine has been prepared by reaction of difluoro-amine with boron trichloride,1 phosgene (carbonyl chloride),2 or hydrogen chloride 2 treating a mixture of sodium azide and sodium chloride with fluorine 3 reaction of chlorine trifluoride with ammonium fluoride 4 reaction of chlorine with diflu oro-amine in the presence of potassium fluoride 5 and photolysis of tetrafluorohydrazine and sulfinyl chloride (thionyl chloride).6... [Pg.34]

The reaction between sodium fluoride and phosgene in liquid HCN produces COF along with CO(CN)F (in 14% yield) [2068a,2070]. In contrast, phosgene reacts with a mixture of potassium fluoride and BrCN to give F3CNCO [2210]. [Pg.341]

Since the volatile gases include sulfur tetrafluoride and thi-onyl fluoride, which possess toxicities comparable to that of phosgene, caution must be exercised in their disposal. A suitable procedure is to condense the volatile gases in a trap cooled in a mixture of acetone and solid carbon dioxide, and then to allow this material to pass slowly through an empty polyethylene bottle, which serves as a safety trap, and into a stirred aqueous potassium hydroxide solution. [Pg.117]

A mixture of calcium fluoride ("fluorspar" 0.08 mol), potassium chloride (0.1 mol) and phosgene (0.14 mol), maintained at 500 C and about 3.4 MPa over a period of 63 h, gave a mixture consisting of COCIF, COFj and unconverted COCl. The solid residue consisted of a CaClj.KCl phase no CaFj.CaCl was detected, and 79% of the CaF was converted. Under similar conditions, maintained over 24 h, 67% of the CaF was converted and, after 4 h. [Pg.689]

ALGOFRENE TYPE 2 (75-71-8) Contact with water causes slow decomposition. Reacts, possibly violently, with barium, sodium, and potassium. Violent reaction with molten aluminum, magnesium. Undergoes thermal decomposition when exposed to red-hot surfaces or fire, forming chlorine, hydrogen fluoride or chloride, phosgene, and carbonyl fluoride. Attacks some plastics, rubber, and coatings. [Pg.63]
