ABSTRACT:
Crystalline 2-layer LiOH.2Al(OH).sub.3.nH.sub.2 O, preferably supported by a porous substrate, is prepared by treating crystalline 2-layer LiX.2Al(OH).sub.3.nH.sub.2 O, where X is anion, with a LiOH solution or other hydroxide ion source. The so-formed crystalline 2-layer LiOH.2Al(OH).sub.3.nH.sub.2 O is particularly suitable for exchange of the OH ion with larger X' ions to produce other crystalline 2-layer LiX'.2Al(OH).sub.3.nH.sub.2 O.
