Crystalline arsenic silicate zeolite useful as catalyst - e.g. in methanol conversion to olefin cpd., is produced by hydrothermal synthesis from silica and arsenic tri:oxide |
| 摘要 |
<p>New crystalline As silicate (I) has zeolite structure. (I) is produced by heating SiO2 and As2O3 in an aq. hexamethyl-enediamine (II) soln. at 100-200 degrees C under autogenous pressure and crystallisation. (I) is useful as catalyst in hydrocarbon conversions, esp. in the conversion of MeOH (or Me2O) to (2-4C) olefins.</p> |
