Abstract
The synthesis of Dodecasil 1H was studied in the system SiO2/1-adamantylamine/NH3/water with the objective of controlling the particle size and the morphology of the crystals. Since nucleation occurs in a very early stage of the synthesis, the heating rate to the final temperature have a strong influence on both parameters. Using seed crystals and such a heating programme, the expensive template 1-adamantylamine can be reduced to so small amounts, that a nearly template free pore system is achieved. The emptiness of the pore system was demonstrated from adsorption measurement using He and H2.
