Carbon monoxide complex with hydrogen fluoride

A substantial portion of fhe gas and vapors emitted to the atmosphere in appreciable quantity from anthropogenic sources tends to be relatively simple in chemical structure carbon dioxide, carbon monoxide, sulfur dioxide, and nitric oxide from combustion processes hydrogen sulfide, ammonia, hydrogen chloride, and hydrogen fluoride from industrial processes. The solvents and gasoline fractions that evaporate are alkanes, alkenes, and aromatics with relatively simple structures. In addition, more complex... [Pg.44]

Research has shown that when polychlorpinen, ammonium nitrate, and superphosphate are present together in the soil, phosgene, carbon monoxide, nitric oxide, hydrochloric acid, ammonia, hydrocyanic anions, ozone, hydrogen fluoride and phosphide, etc. could appear in the air over the beet fields. Photooxidants could also appear. Airborne toxic compounds over this crop were noted in areas after precipitation with little wind, and with an air temperature of over 2CP . The combined and complex activity of pesticides and other chemical compounds led people who manually sowed beets to develop symptoms of poisoning. [21]... [Pg.45]

Since calcium fluoride is insoluble in water, loss of fluoride in this form is relatively benign. The fluoride present in the slag, however, may be mobilized into the water phase if the hot slag is contacted with water to fracture the material for use as fill. The fluoride not captured in the slag is converted to silicon tetrafluoride and hydrogen fluoride which leave the furnace with the phosphorus vapor and carbon monoxide. However, they are absorbed by the water stream of the phosphorus condensers (Eq. 10.11). Thus, the water from the phosphorus condenser contains dissolved and colloidal phosphorus and dissolved fluoride as the ion and as the complex fluosilicate anion. [Pg.298]

When trifluoroiodomethane is treated with a solution of chromium(u) ions, the brownish orange [Cr(OH2)s(CF3)] + is obtained. This complex is stable towards aquation compared with the corresponding methylchromium species, slowly giving hydrogen fluoride and carbon monoxide but no detectable fluoroform. With sodium fluoride [Cr(OH2)4F(CFs)]+ is formed. The formation of Cr[C(CFs)2(CN)]2 in good yield from Cr(OAc)2 and (CF3)2CH CN under naild conditions has been reported. ... [Pg.309]
