Preparation and characterization of Ni-CaO catalyst for one step synthesis of MIBK (Methyl isobutyl ketone) from acetone

摘要

One step synthesis of MIBE (methyl isobutyl ketone) from acetone over co-impregnated Ni-CaO catalyst and Ni effect on the thermal decomposition of CaCO_3 into CaO were studied.Bulk calcium acetate,one of catalyst precursors,decomposed into CaCo_3 and acetone at 400-450 deg C,and CaCO_3 into CaO and CO_2 at 700 deg C.But,when nickel acetate for 2 wt
