Abstract: Aluminum chlorohydroxide represented by the formula: Al2(OH)x Cly, wherein x and y range from 1 to 3.5 and 5 to 2.5, respectively, is produced by reacting aluminum oxide or hydroxide with an amount of hydrochloric acid which is (1/2.5) to (1/4) of the stoichiometric amount for obtaining aluminum trichloride, at a temperature in the range from 100 DEG C to 160 DEG C, and at a pressure in the range from 0.1 kg/cm2 to 4 kg/cm2 for a period of from 2 to 10 hours.

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.
