Reaction products of polyalkenyl succinimides with an epoxy alkanol 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 reaction products are formed via a two-step reaction in which a polyalkenyl succinic anhydride precursor is reacted with an alkenylpolyamine to form a polyalkenyl succinimide intermediate which, in turn, is reacted with an epoxy alkanol.
