Structure-controlled effect of organic templates on zeolite crystallization

  • Published:
Molecular Engineering

Abstract

The effect of organic templates on the synthesis of molecular sieves is considered on the basis of quantum-chemical calculations. The ionization potential, dipole moment and geometric configuration are calculated for diamines, heterocyclic nitrogen-containing substances, and alkyl-substituted amines. The ability of these molecules to form microporous structures is discussed. It is shown that the small-sized molecules with high dipole moment are effective templates for a great number of zeolite structures. Molecules with a complicated configuration exhibit high stereospecificity in the zeolite formation.
