摘要： A method of stabilizing asphaltenes in a petroleum hydrocarbon fluid is disclosed. The method includes contacting the petroleum hydrocarbon fluid with a polybenzoxazine comprising repeating structural units of Formula (I): wherein R1 is hydrogen, a C1-30 alkyl, a C3-30 cycloalkyl, a C6-30 aryl, a C7-30 alkylarylene, a C7-30 arylalkyl, a C5-30 heteroaryl, or a C3-30 heterocycloalkyl; and R2 is a C1-30 alkyl, a C3-30 cycloalkyl, a C6-30 aryl, a C7-30 alkylarylene, a C7-30 arylalkyl, a C5-30 heteroaryl, or a C3-30 heterocycloalkyl.

摘要： A method of stabilizing asphaltenes in a petroleum hydrocarbon fluid comprises contacting the petroleum hydrocarbon fluid with a mixed phenol aldehyde derived from an aldehyde and two or more unsubstituted or alkyl-substituted monophenols, the two or more unsubstituted or alkyl-substituted monophenols comprising a first phenol which is a C1-20 linear or branched alkyl monophenol; and a second phenol which is unsubstituted or a C1-20 linear or branched alkyl monophenol different from the first phenol, wherein the molar ratio of the first phenol relative to the second phenol is about 4:1 to about 1:4.
