Abstract
Inventia se refera la un procedeu de preparare hidrotermala, la 160 degree C, timp de 72 h, a unui zeolit cu structura tip ZK-19, din compozitii initiale libere de agenti de dirijare structurala, caracterizate prin: SiO2/Al2O3=15-16; (Na2O+K2O)/Al2O3=9-11; H2O/Al2O3=190-300. Produsul obtinut manifesta selectivitate în adsorbtie si caracter hidrofob: capacitate de absorbtie a vaporilor de apa 1,5...1,9% si a n-heptanului 11,8% si prezinta, totodata, o structura ultrastabila termic.
