Abstract: Zeolite mouldings contg. basic Al chloride binders are produced by mixing zeolite powder with binder, kneading moulding mixt. opt. with addn. of water, and calcining at =500 degrees C. Zeolite powder used is capable of flowing and contains 40-70 wt.% water. Basic Al chloride is prepd. by treating aq. solns. contg. Al and Cl ions with solns. of amines having mol.wt. 250-500 in a water-immiscible organic solvent. The aq. and organic phase are then sepd. from one another. The basic Al chloride is recovered from sepd. aq phase by a standard method, provided that the aq. soln. contains max. 25g/l Al and the organic phase contains max. 0.35 mol/l amine. Amorphous basic Al chloride used in an excellent binder for zeolite moulding prodn. Mouldings obtd. have good absorption and catalytic properties.
