- Abstract
An expedient method of silica supported heteropolyacid (HPA) catalyzed liquid phase dehydration of aldoxime to nitrile and secondary alcohols to alkenes were developed. Supported HPA was prepared by wet impregnation method and characterized by various analytical techniques such as X-ray diffraction, FT-IR, and NH3-TPD analysis. HPW-SiO2 was found to be the most efficient catalyst amongst the prepared HPA and was found to be reusable for dehydration reaction under mild operating conditions giving high yields of the desired products.
