  • Process for preparing basic aluminum chlorides
    Patent number: 4203812
    Abstract: When aqueous solutions of aluminum chloride or of basic aluminum chloride having the formula Al.sub.2 (OH).sub.m Cl.sub.6-m wherein m is a number from 0 to 5.3 are submitted to electrolysis chlorine is removed and the Al/Cl ratio of the solution increases. The electrolysis is performed without diaphragm. Graphite anodes cannot be used. It is possible to process the resulting solutions to solid basic aluminum chloride having the formula Al.sub.2 (OH).sub.n Cl.sub.6-n wherein n is a number from 1 to 5.34.

  • Process for the preparation of basic aluminum chlorides
    Patent number: 3953584
    Abstract: For the preparation of basic aluminum chlorides by reaction of AlCl.sub.3 with aluminum hydroxides, there are generally used aluminum hydroxides easily soluble in mineral acids. According to the process of the invention, however, also such aluminum hydroxides which are soluble in mineral acids only at temperatures above 80.degree.C and which moreover are very cheap may be used when they are reacted with aluminum chloride hexahydrate suspensions at a temperature of from 110.degree. to 150.degree.C.
