Document Type and Number:
Japanese Patent JP2003502267
Kind Code:
A
Abstract:
This invention describes a general process in which, by means of the use of tensioactives, it permits a reduction of the synthesis times for crystalline microporous materials based on silica with ducts with a pore opening formed of 10 or 12 tetrahedra of silica. This procedure is based on the addition of a tensioactive, which can be cationic, anionic or neutral, to the reaction mixture wherein the zeolite is formed. In addition, this new synthesis method increases the efficiency of the reagents used in the synthesis of zeolites and the stability of the materials formed, permitting the size of crystal to be controlled. And in cases wherein there exists competition for the growth of different microporous materials, it is possible to promote the appearance of one phase with respect to another competing with it by a proper selection of surfactant.
