 Title    Zur Bildungskinetik des Zeolithen ZSM-11 On the Kinetics of Formation of the Zeolite ZSM-11  
 Abstract    The synthesis of pentasil ZSM-11 with Bu4N H S 0 4 as template was first optimized in a teflon-coated autoclave of 200 ml volume (163 °C, 3 days) and then transferred to a stirring autoclave of 1000 ml volume. The latter allowed sampling over the period of crystallization. Pure ZSM-11 crystallized at temperatures between 150 and 180 °C. In this range the induction period decreased from 15 to 2 hours while the rate of crystallization was enhanced from 2.5 to 5.6% per minute. From these values energies of activation for nucleation and crystallization were determined (99.8 and 43.4 kJ mol-1).
