  • PROCESS FOR THE PREPARATION OF 1,1,1,2-TETRAFLUOROETHANE
    Publication number: 20110201495
    Abstract: The present invention relates to a process for preparing a co-precipated Cr2O3/Al2O3 catalyst promoted by Zinc, said process comprising co-precipatation of chromium and aluminum metal hydroxides from corresponding trivalent metal salt solutions using NH4OH, NaOH or KOH as a base and followed by calicination to give mixed oxide precatalyst in amorphous from which is impregnated with an activity promoting amount of Zinc compound.
