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.
本发明公开了一种稳定石油烃流体中沥青质的方法。该方法包括将石油烃流体与包含式(I)重复结构单元的聚苯并恶嗪接触:
其中 R1 是氢、C1-30 烷基、C3-30 环烷基、C6-30 芳基、C7-30 烷芳基、C7-30 芳烷基、C5-30 杂芳基或 C3-30 杂环烷基;R2 是 C1-30 烷基、C3-30 环烷基、C6-30 芳基、C7-30 烷芳基、C7-30 芳烷基、C5-30 杂芳基或 C3-30 杂环烷基。
