Abstract

1290749 Aluminium fluoride STAUFFER CHEMICAL CO 4 May 1970 21344/70 Heading C1A AlF 3 is prepared continuously by reacting Al(OH) 3 with gaseous HF in countercurrent, in at least two fluidized beds operating in series such that, after start up, no external heat is supplied. Preferably a two-bed system is used, the upper bed, to which Al(CH), is added, being kept at at least 600‹ C. and the lower bed being kept at 950‹ C. or above, the maximum temperature in any bed being below 1300‹ C. The reaction is preferably carried out at subatmospheric pressure.
