Abstract
A study into the disassembly and organisation steps of the ADOR process has been undertaken through in situ Pair Distribution Function (PDF) analysis. Three aqueous systems (water, 6 M HCl and 12 M HCl) were introduced to a parent zeolite germanosilicate UTL in a cell. Hydrolysis could be clearly seen when UTL was exposed to water over a period of 8 hr, forming the disorded layered material, IPC-1P. In hydrochloric acid, the hydrolysis step is too quick to observe and a Ge-Cl containing species could be seen. In 6 M HCl, the rearrangement of the interlayer region began after an induction period of 8 hr, with the process still occuring after 15 hr. In 12 M HCl, the rearrangement appears to have come to an end after only 6 hr.
