ABSTRACT:
Enaminones of polyalkenylsuccinimides are used as effective antifoulants in liquid hydrocarbonaceous mediums, such as crude oils and gas oils, during processing of such liquids at elevated temperatures. The enaminones are formed via reaction of polyalkenylsuccinimide and a dicarbonyl compound. The polyalkenylsuccinimide intermediate is first formed via reaction of polyalkenylsuccinic anhydride and polyamine.
