摘要： 1,272,484. Halogenated hydrocarbons. MONTECATINI EDISON S.p.A. 11 July, 1969 [11 July, 1968], No. 35009/69. Heading C2C. A mixture of chlorinated and/or fluorinated derivatives of methane containing monochlorodifluoromethane is prepared by (1) reaction of methane and chlorine in a fluidized bed of inert granular material at a temperature of from 350‹ to 500‹ C. in the presence of a first recycle mixture comprising halogenated hydrocarbons and (2) reaction of the mixture resulting from (1) with anhydrous hydrogen fluoride and a second recycle mixture comprising mainly dichloromonofluoromethane together with minor amounts of other halogenated hydrocarbons at a temperature of from 200‹ to 450‹ C. in the presence of a solid catalyst comprising fluorinated alumina. The first recycle mixture may be fed into the fluidized bed at a point after the point of introduction of the methane and chlorine. The final mixture may, for the purpose of purification, be distilled into two successive distillation columns, the bottoms from the first column being recycled as first recycle mixture and the bottoms from the second column being recycled as second recycle mixture. Apart from monochlorodifluoromethane, the final mixture may include CHF 3 , CC1F 3 and CC 12 F 2 .

摘要： 1,274,030. Fluorination catalysts. MONTECATINI EDISON S.p.A. 24 July, 1969 [25 July, 1968], No. 37228/69. Heading BIE. [Also in Division C2] A catalyst for the fluorination of hydrocarbons comprises aluminium fluoride or fluorinated alumina containing compounds of iron and chromium, the iron and chromium being present in amounts of from 0.1 to 5% and 0.05 to 8.5% by weight, respectively, based on the total weight of catalyst. The catalyst may also contain a nickel compound, the nickel being present in an amount of up to 5%. The metals may be present in the catalyst in the form of halides, particularly fluorides, or oxides or oxy-halides and may be introduced into the aluminium fluoride or alumina in the form of chlorides or nitrates in solution after which the composition is activated by heating and fluorinated. The catalyst is stated as being useful for the gas-phase fluorination of halogenated ethanes using hydrogen fluoride, the gas-phase chlorofluorination of ethylene using chlorine and hydrogen fluoride, and the gasphase disproportionation of 1, 1, 2-trifluoro-1, 2, 2-trichloroethane (see Division C2).
