Hydrothermal conversion of piperazine–ZSM-39 into tetrapropylammonium-silicalite-1
Abstract
The hydrothermal conversion of the clathrasil PIP–ZSM-39 into the silica molecular sieve precursor TPA-silicalite-1 (PIP = piperazine, TPA = tetrapropylammonium) has been followed by X-ray powder diffraction and pH measurements.
