Abstract

The reaction of ethanol with propylene oxide over calcined layered double hydroxides (CLDH) was investigated. The results show that CLDH has a good activity and a good selectivity, but the activity and the selectivity of CLDH decrease when CLDH reforms LDH - the so called memory effect. The influence of the memory effect on the CLDH returning to LDH was studied by the hydration reaction. It is shown that the memory effect is not complete, and the decreases of the Mg/Al molar ratio of LDH and the crystallite size due to the increase of the hydration reaction time result in the drop of the activity and the selectivity.
