摘要：Reaction products of polyalkenylsuccinimides with triazoles and aldehydes areused as effective antifoulants in liquid hydrocarbonaceous mediums, such as crude oilsand gas oils, during processing of such liquids at elevated temperatures. The reactionproducts are formed via a two-step reaction in which a polyalkenylsuccinic anhydrideprecursor is reacted with an alkenylpolyamine to form a polyalkenylsuccinimideintermediate which, in turn, is reacted with a triazole and an aldehyde.
