Acetone is a VOC exempt solvent which is widely used as a green solvent in many industries. In this regard, acetone is preferred to be produced because of the environmental advantages. The conversion of IPA (isopropyl alcohol) to acetone is an endothermic gas-phase reaction which produces hydrogen as a byproduct [1]. In literature ...
