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*C to 160*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.
