Process for preparing a pentasil zeolite |
| abstract |
Templating compounds of the formula: (HO-C2H4)3N(+)-(CH2)n-N(+)(C2H4-OH)3 2 Br(-) wherein n equals 3, 4 or 5 are produced by reacting triethanolamine with alpha , omega dibromoalkanes, for example in the presence of a solvent. One can also react dibromoalkane with the triethanolamine in dropwise manner at reaction temperature. The product is subsequently recovered by known methods. The templating compositions can be used for the preparation of the zeolites of the pentasil types. These zeolites have the composition represented by the summary formula: (0.4-0.7)Na2O/(0.3-0.6)Q2O/Al2O3/(30-80)SiO2/(4-10)H2O and have the following X-ray diffraction pattern: -d ANGSTROM I/Io -11.0 +/- 0.2 30-70 -10.0 +/- 0.2 30-80 -4.4 +/- 0.1 10-20 -4.3 +/- 0.1 10-20 -3.85 +/- 0.05 100 -3.74 +/- 0.05 40-65 -3.66 +/- 0.05 20-40 -3.43 +/- 0.03 15-25 -2.01 +/- 0.02 5-15 -1.99 +/- 0.02 5-15 - They are prepared by utilizing an aqueous suspension of precipitated silica and mixing with an aqueous sodium aluminate composition and an aqueous solution of the template compound. This mixture is then converted under autogeneous pressure, the product is dried and then calcined. The pentasil type zeolites can be used in the conversion of methanol into hydrocarbons. |
