Studies on the Ageing Mechanism for the Directing Agent of Zeolite L

Abstract

Abstract: The ageing mechanism for the directing agent of zeolite Lwas studied by means of NMRand Laser-Raman spectroscopyThe experimental results show that after mixing the sources of alumina and silica the polymerization between aluminate and silicate anions is very rapid and at the same time the silicate anions of high degree of condensation are depolymerizedThe controlling step of the ageing reaction for the directing agent of zeolite Lis directional polymerization between aluminosilicate oligomers or between aluminosilicate and silicate oligomers.

Key words: Zeolite L, Directing agent. NMR, Raman
