    摘要: 1,1,1-Trifluoro-2,2-dichloroethane is prepared by reacting, in the gas phase, 1,1,1-trifluoro-2-chloroethane with chlo­rine. The formation of the by-product 1,1,1-trifluorotri­chloroethane is prevented by effecting the reaction with a chlorine/organic compound molar ratio of not higher than 1 at a temperature of from 350°C to 450°C and with residence times of the reagents in the reactor of from 5 to 25 seconds.

    摘要: A solvent composition for defluxing printed circuits at room temperature comprises 4 to 10% ethanol , 0.5 to 1.5% a C₁₋₃ nitroalkane, 0.5 to 10% of a C₁₁₋₁₈ alkyl mono- or diester of phosphoric acid and balance perfluorochlorocarbon. In the defluxing process the printed circuit is immersed in the composition. The composition is good for dissolving flux but does not corrode the apparatus.
