Acetone Production - Scholarworks at WMU

The cumene process method is quite expensive, since it requires the raw materials and extra separation equip-ment to separate acetone from many different materials (Moore & Parker, 2007; Coulson et al., 1999b). Therefore, this study focuses on the more economic method of decomposition of isopropyl alcohol over the cumene process method.
