COMBUSTION SYNTHESIS OF NANOCRYSTALLINE ALKALI AND ALKALINE EARTH METAL OXIDES OR MIXTURE THEREOF AND ITS APPLICATIONS

摘要

The present invention relates to the development of Nano crystalline heterogeneous solid base catalyst comprising alkali and/or alkaline earth metal oxide and/or of mixture thereof by self-propagating liquid combustion synthesis method wherein said catalyst composition possesses high catalytic activity. The particle size obtained is in the range of 10-20 nm. Nano crystalline nature increases catalytic activity of the said catalyst and catalyst has application in condensation and Trans esterification reactions. The process for the preparation comprises of various steps where dissolving, evaporation, combustion and calcination are the important steps.
