Abstract

1309361 Hydrofluorination catalysts DYNAMIT NOBEL AG 1 Jan 1971 [3 Jan 1970] 148/71 Addition to 1261501 Heading B1E [Also in Division C2] Hydrofluorination catalysts are obtained by the hydrofluorination of y- and/or #-Al 2 O 3 impregnated with a bismuth salt and a manganese salt, and consist of, by weight, 0.1-20% Bi, 35-66% F, 24-42% Al, 0.1-10%Mn and the remainder O. They may be regenerated by burning off carbonaceous deposits.
