Title
(EN) METHOD FOR PREPARING MOLECULAR SIEVES
(FR) PROCÉDÉ DE PRÉPARATION DE TAMIS MOLÉCULAIRES
Abstract
(EN)
A method for synthesizing a molecular sieve comprising providing a reaction mixture sufficient to synthesize the molecular sieve, maintaining the reaction mixture under crystallization conditions, monitoring at least one viscometric parameter of the reaction mixture, and determining an endpoint based on the monitoring of the at least one viscometric parameter.
(FR)
L'invention concerne un procédé destiné à synthétiser un tamis moléculaire et comportant les étapes consistant à mettre en place un mélange réactif suffisant pour synthétiser le tamis moléculaire, à maintenir le mélange réactif dans des conditions de cristallisation, à surveiller au moins un paramètre viscométrique du mélange réactif et à déterminer un point de fin en se basant sur la surveillance du ou des paramètres viscométriques.
