Project objective
In the present application we propose the synthesis of Hg-Na clusters entrapped within zeolite cages in faujasite structures prepared by reduction of Hg- Na exchanged zeolite Y or X with the appropriate reductor (i e alkali-metal vapor alkali-azide. n-butyl-lithium or sodium disolved in liquid ammonia or amines ) . The obtained solids are going to be characterised by ESR Vis-U.V. and MAS-NMR spectroscopies and the environment around the Hg into the clusters formed within the zeolite is going to be studied by EXAFS. The stability of the Hg- Na is going to be studied by microcalorimetry and ESR spectroscopy by adsorption O2. Finally the catalitic activity in side-chain alkylation of toluene with ethylene and butene isomerisation are going to be measure in a flow reactor. These catalysts could extend the basicities availables for base catalys reactions to the superbasicity range (pKa>35).
