摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing type A zeolite whose all cation sites are occupied by the cations of sodium, calcium and/or magnesium, potassium, and hydronium, whose water absorbing capacity is >=23%, which does not absorb nitrogen and accordingly not desorb it, which can extend the pot life of a polyurethane(PU) composition when blended in the composition, and which can be added in a quantity extremely lager than conventional desiccants and is insensitive to the deterioration of a hydroxylated substance. SOLUTION: An aqueous suspension of zeolite 3A, 4A, or 5A, an aqueous solution of calcium salt, potassium salt, or calcium salt and potassium salt, and an acid solution are brought into contact with each other simultaneously or in an arbitrary order. The resultant solid is filtrated, washed, and finally dried and activated.

摘要： La présente invention concerne un procédé de préparation des zéolites d e type A dont l'ensemble des sites cationiques est occupé par des cations sodium, calcium et/ou magnésium, potassium et hydronium, qui présentent l'avantage d'avoir une capacité d'adsorption d'eau .gtoreq. 23 %, qui n'adsorbent pas et donc n e peuvent pas désorber l'azote et qui, incorporées à des résines polyuréthanes (PU), permettent nettement plus d'augmenter la durée de vie en pot des formulations PU auxquelles elles sont incorporées que les agents de dessication zéolitiques de l'art antérieur tout en étant peu sensibles à l'âge du composé hydroxylé. Le procédé, objet de la présente invention, consiste à mettre en contac t - une suspension aqueuse de zéolite 3A, 4A ou 5A - une solution aqueuse de sel(s) de calcium ou de potassium ou des solutions de sel(s) de calcium et de potassium, - une solution d'acide, simultanément ou non et dans un ordre quelconque, puis filtrer et laver le solide obtenu, et enfin le sécher et l'activer.
