Process for producing basic aluminum chlorides
Abstract
Abstract Basic aluminum chlorides of the formula Al2(OH)6 nCln wherein n 1-5 are produced by trickling 5 to 15% by weight hydrochloric acid solution down through a fixed bed of aluminum particles of 0.3 to 0.8 kg/liter density and withdrawing a solution of the product having a pH of about 3 to 4. The average residence time of the fluid in passing through the bed is about 2 to 8 hours. Advantageously the lower part of the bed is heated externally to maintain the temperature at about 70* to 95*C to promote continued reaction. Since the reaction is exothermic a reflux condenser may be provided to remove heat resulting from the first contact of hydrochloric acid with aluminum, the condenser allowing by-product hydrogen to escape.
