Title (EN) PROCESS FOR PREPARING FINE ZEOLITE PARTICLES
(FR) METHODE DE PREPARATION DE PARTICULES FINES DE ZEOLITE
Abstract: front page image
(EN)A process for efficiently preparing fine zeolite particles comprising synthesizing zeolite in the presence of an alkaline earth metal-containing compound and/or with controlling the preparation process of zeolite, thereby giving fine zeolite particles being composed of crystalline aluminosilicate, the fine zeolite particles having a fine average primary particle size, being excellent in the cationic exchange properties and the oil-absorbing ability, having a fine average aggregate particle size, and being excellent in the dispersibility; fine zeolite particles obtainable by the above process; and a detergent composition comprising the fine zeolite particles, the detergent composition being excellent in the detergency.
(FR)L'invention concerne une méthode qui permet de préparer efficacement de fines particules de zéolite. La méthode consiste à synthétiser le zéolite en présence d'un composé contenant un métal alcalino-terreux, et/ou à régler le processus de préparation du zéolite pour obtenir des particules de zéolite fines composées de silicate alumineux cristallin. Les particules de zéolite fines présentent une granulométrie primaire moyenne fine, d'excellentes propriétés d'échange cationique et d'absorption d'huile, une granulométrie composite moyenne fine et une excellente dispersabilité. L'invention concerne des particules de zéolite fines pouvant être obtenues par ladite méthode, et une composition détergente présentant une excellente détergence.
