ABSTRACT:
Phosphorus derivatives of polyalkenylsuccinimides and methods of use of such derivatives as antifoulants in liquid hydrocarbonaceous mediums, such as crude oil, during processing at elevated temperatures are disclosed. The derivatives are formed via reaction of a polyalkenylsuccinimide intermediate with formaldehyde and a phosphorus compound having at least one acidic hydrogen P--H bond. The intermediate is first formed via reaction of polyalkenylsuccinic anhydride and polyamine.
