A PROCESS FOR SYNTHESIS OF ATO MOLECULAR SIEVE FRAMEWORK

摘要

The present invention relates to a process for the synthesis of ATO molecular sieve framework comprising forming a reaction medium comprising of reactive sources Al2O3, P2O5 and /or silica and a templating agent and subjecting the reaction medium to microwave hydrothermal heating until crystals of ATO framework are formed. The templating agent used in the reaction medium is a long chain quaternary ammonium dihydroxide organic moiety having C5-C10 linear chain alkane, alkene or alkyl. The crystalline ATO type molecular sieve framework obtained by the process of the present invention is pure and completely free from commonly observed major impurity phase, namely AEL framework.
