摘要：

1,1,1-Trichloroethane is fluorinated by HF at ambient temperature and pressure in the presence of organic layer catalysts, derived from CH3CCl3, C2Cl4 or CH3CCl2CH3 and supported on SF4-fluorinated gamma-alumina or CCl4-chlorinated gamma-alumina, to give CH3CCl3-nFn. Related behaviour is observed when CH3CCl2CH3, CH2ClCCl3, CHCl2CHCl3 and CHCl=CCl2 are fluorinated using the supported organic layer catalyst derived from CH3CCl3. The product distributions observed suggest that the reactivity of the substrates can be correlated with their ability to undergo dehydrochlorination. The behaviour of CHCl3, CCl4, CCl2FCClF2 and CCl3CF3 under similar conditions is also reported.
