HYDROHALOGENATION OF VINYL TERMINATED POLYMERS AND THEIR FUNCTIONALIZED DERIVATIVES FOR FOULING MITIGATION IN HYDROCARBON REFINING PROCESSES

摘要

A compound useful for reducing fouling in a hydrocarbon refining process is provided. A method for preparing the compound includes hydrohalogenating a polymer having a vinyl chain end to obtain a halogen-containing terminal group, and reacting the terminal group with a polyamine. Methods of using the compound and compositions thereof are also provided.

1. A compound represented by wherein R1 is a branched or straight-chained C10-C800 alkyl or alkenyl group; m is an integer between 0 and 10 inclusive; R2 is represented byor —CH2—CH2—CH2—*, wherein the asterisk (*) indicates a connecting point of R2 with the nitrogen that connects with R3;
R3 is a C1-C4 branched or straight chained alkylene group; R31 is hydrogen or —R8-R9, wherein R8 is defined the same as R2 above, and R9 is branched or straight-chained C10-C800 alkyl or alkenyl group, or R8 and R9 together are a C1-C4 branched or straight chained alkyl group optionally substituted with one or more amine groups;and further wherein the —N(R31)—R3— repeat unit is optionally interrupted in one or more places by a nitrogen-containing heterocyclic cycloalkyl group; and
R4 and R5 are each independently selected from (a) hydrogen, (b) —R6-R7, wherein R6 is defined the same as R2 above, and R7 is a C10-C800 branched or straight chained alkyl or alkenyl group, or (c) a bond connected to R31 in the m-th —N(R31)—R3— repeat unit.
