The preparation of molybdenum phosphide pillared bentonite catalyst has been carried out with various variations of bentonite-MoP concentrations, namely 2, 4, 6, 8 and 10 meq/g. The purpose of this study was to apply the bentonite-MoP catalyst during the dehydration of isopropyl alcohol to diisopropyl ether and to characterize the best synthesis results using XRD, SEM-EDS, FTIR and GSA.
