Description:
The objective of this work was to evaluate the feasibility of methods for elucidation of the thermodynamic silicic acid reaction pathways for the initialisation of zeolite syntheses by theoretical and experimental means. This was done by evaluating the results of the respective methods. Amorphous silica (SiO2(am)) and water are considered to give silicic acid species as products. The compensation of the deviation between experimental and theoretical investigation should follow in coming investigations. Improved reactor design is necessary to achieve ideal measurement conditions. In-situ and automated analytic measurements needs to be integrated into the reactor design to minimize measurement errors. The introduction of activity coefficients are recommended. The feasibility of the methods are applicable to provide information on measurement efficiency, and gives useful trends towards the elucidation of silicic acid reaction pathways for the initialisation of zeolite syntheses.
