The green chemicals based on bio-surface-active ionic liquids attracted great attention in the petroleum industry as a result of their high efficiency as multipurpose additives for the petroleum crude oils and their products. In the present work, the chemical structure of cardanol produced from cashew nut shell oil was modified and etherified with epichlorohydrine, tetraethylene glycol, and ethanolamine to produce branched non-ionic surfactants. The amine groups of the cardanoxy ethoxy branches were quaternized and polymerized using 2-acrylamido-2-methylpropane sulfonic acid to produce dendritic protic ionic liquid. The chemical structure, surface activity, ζ potential, and aggregation characteristics of the new modified dendritic non-ionic cardanoxy polyphenol and its poly(ionic liquid) in aqueous solution were analyzed and identified. Their applications as asphaltene dispersants and demulsifiers for the heavy petroleum crude oil emulsions were investigated to confirm their promising performances.

腰果壳油作为绿色油田化学品重油原油乳液的两亲性聚（离子液体）树枝状分子的合成及应用

由于基于生物表面活性离子液体的绿色化学品作为石油原油及其产品的多用途添加剂的高效率，因此在石油工业中引起了极大的关注。在本工作中，对腰果壳油生产的腰果酚的化学结构进行了改性，并用表氯醇，四甘醇和乙醇胺将其醚化，以生产支链非离子表面活性剂。使用2-丙烯酰胺基-2-甲基丙烷磺酸使对戊氧基乙氧基支链的胺基季铵化并聚合以产生树枝状质子离子液体。分析和鉴定了新型改性的树枝状非离子型环氧烷氧基多酚及其聚（离子液体）在水溶液中的化学结构，表面活性，ζ电势和聚集特性。
