PREPARATION OF ZEOLITE TS-1 NANOCRISTALINA WITH HIERARCHY POROSITY THROUGH SILANIZATION OF CRYSTALLINE NUCLEES FOR ITS CATALYTIC APPLICATION IN OLEFINE EPOXIDATION WITH ORGANIC HYDROPEROXIDES.

摘要

Preparation of zeolite TS-1nanocrystalline with nested porosity by silanization ofcrystalline nuclei for catalytic application in epoxidation ofolefins with organic hydroperoxides.;The present invention relates to aprocedure for obtaining zeolitic materialsTS-1 type nanocrystalline with high surfacespecific and hierarchical porosity, as well as its applicationcatalytic in processes of epoxidation of olefins withorganic hydroperoxides The procedure for obtaining saidzeolitic materials comprises a step of preparing asynthesis mixture of a zeolite precursor solutionTS-1, a low pre-crystallization stagetemperature, a stage of silanization, a stage of crystallizationhydrothermal and a material recovery stage.
