Abstract: A process is described whereby aluminum chlorohydroxide having a controlled chlorine content is prepared by subjecting a mineral containing aluminum oxide or hydroxide (e.g. bayerite, gibbsite, diaspore, boehmite or alumina bayer) is subjected to a preliminary etching with hydrochloric acid at a temperature in the range from 110 DEG to 150 DEG C, the solution so obtained is neutralized with ammonia and the desired aluminum chlorohydroxide (e.g. Al2(OH)5Cl) is crystallized out.

Abstract: 1488444 Aluminium chlorohydroxide SNAMPROGETTI SpA 21 March 1975 [28 March 1974] 12043/75 Addition to 1410087 Heading ClA An aluminium chlorohydroxide of formula Al 2 (OH) x Cl y (in which x is 1-4 and y is 5-2) is prepared by reacting hydrochloric acid with an aluminium oxide or hydroxide at a temperature exceeding 160‹ C. but not exceeding 270‹ C., the amount of aluminium compound available for reaction with the hydrochloric acid being at least the stoichiometric amount needed to produce AlCl 3 . Preferably Bayer alumina is used.
