| titleOfInvention | Synthetic zeolites and process of preparing the same |
| abstract | An acid stable synthetic zeolite having the mordenite crystal structure and the formula (Na1K1Ca/2)2Al2Si9-10O22-24 (A2O)0-6.7 and being capable of absorbing molecules having a size larger than 5<\>rA, which is claimed per se, is produced by heating a mixture containing a water-insoluble source of silica and aqueous alkali metal silicate at a temperature less than 190 DEG C. for a time sufficient to prepare the zeolite. The mixture is preferably heated under autogeneous pressure and saturated vapour pressure. The source of silica is preferably a volcanic glass such as pumice. If the source of silica is amorphous silica a water-soluble aluminate is also present during heating. The zeolite may be subsequently hydrolysed to yield an acid stable synthetic mordenite having the formula H2Al2Si9-10O22-24(H2O)0-6.7, capable of absorbing molecules having a size larger than 5A DEG , which is also claimed per se. The hydrolysis is suitably carried out using IN. HCl. The mordenites of this will absorb n-heptane, benzene and cyclohexane in signicant amounts. |
