Abstract
1381228 Powdered AlCl 3 SOC ITALIANA RESINE S I R SpA 31 May 1973 [13 June 1972] 26081/73 Heading C1A Finely powdered AlCl 3 is prepared by introducing a stream of AlCl 3 vapour, velocity at least 0-5 m./sec., and a stream of cold inert gas, velocity at least 2 m./sec., into a sublimate precipitator, the ratio of velocities being 1 : 2 to 1 : 10, the gas streams meeting at an angle of 20-50 and the temperature of the mixed gases not exceeding 70 C. The AlCl 3 vapour which may be mixed with other gases may be at a temperature of 200-800 C. The inert gas stream which may be air or nitrogen may be at 5-35 C. The AlCl 3 vapour may be obtained by sublimation of crude AlCl 3 , by reaction of Al 2 O 3 with Cl 2 in the presence of carbon or by reaction of Al with Cl 2 .
