Reaction products of (a) polyalkenylsuccinic anhydride; (b) secondary, aromatic amines, and (c) hindered alcohols 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 may be formed via a two-step reaction in which the polyalkenylsuccinic anhydride is reacted with the secondary, aromatic amine as a first step. The resulting polyalkenylsuccinimide may then be reacted with a hindered alcohol to form the desired antifoulant. |
