ABSTRACT:
Reaction products of polyalkenylsuccinimides with triazoles and aldehydes 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 polyalkenylsuccinic anhydride precursor is reacted with an alkenylpolyamine to form a polyalkenylsuccinimide intermediate which, in turn, is reacted with a triazole and an aldehyde.
