Preparation method of novel material containing multiple functional groups for two-type oil displacement

The invention relates to a preparation method of a novel material containing multiple functional groups for two-type oil displacement. The method includes: taking maleic anhydride, long-chain fatty alcohol, sodium bisulfite and sodium chloroacetate as raw materials to generate the novel material through esterification reaction, sulfonation reaction and nucleophilic substitution reaction. The novelmaterial takes long-chain fatty alcohol as the raw material, has better temperature resistance and salt resistance and higher interfacial activity compared with a common oil displacement agent, and conforms to the green chemical concept. 本发明涉及一种含有多官能团的两型驱油用新材料的制备方法。以马来酸酐、长链脂肪醇、亚硫酸氢钠、氯乙酸钠为原料，通过酯化反应、磺化反应、亲核取代反应生成不对称型两型驱油用新材料。其特征在于：此类驱油用新材料是以长链脂肪醇为原料，与普通的驱油剂相比有更好的耐温抗盐性，较高的界面活性，符合绿色化学理念。
