All isomers of both pyridinecarboxylate (2-PA; 3-PA and 4-PA) and toluate (o-TA; m-TA and p-TA) can be intercalated into the layered double hydroxide [LiAl2(OH)6]Cl·H2O in water or a water–ethanol mixture at RT to give the fully ion-exchanged first stage intercalation compounds [LiAl2(OH)6]·G·yH2O (G = 2-PA; 3-PA; 4-PA; o-TA; m-TA and p-TA; y = 2.5–3.5). Experiments also showed that using a mixed ethanol–water solvent may improve the crystallinity and decrease the production of Al(OH)3. The… CONTINUE READING
