一种苯羟基阴离子功能化离子液体抗氧化剂及其制备方法
Abstract:
本发明涉及一种苯羟基阴离子功能化离子液体抗氧化剂及其制备方法，属于生物柴油抗氧化剂技术领域。该羟基阴离子功能化离子液体抗氧化剂，由烷基咪唑阳离子或胆碱阳离子与没食子酸阴离子组成，烷基咪唑阳离子和没食子酸阴离子组成烷基咪唑类没食子酸盐离子液体抗氧化剂，胆碱阳离子与没食子酸阴离子组成胆碱没食子酸盐离子液体抗氧化剂。本发明解决现有技术中生物柴油的抗氧化剂的油溶性能差、抗氧化效果一般的问题。
Abstract(English):

The invention relates to a benzene hydroxyl anion functionalized ionic liquid antioxidant and a preparation method thereof and belongs to the technical field of biodiesel antioxidants. The benzene hydroxyl anion functionalized ionic liquid antioxidant comprises alkyl imidazole cations or choline cations and gallic acid anions, the alkyl imidazole cations and the gallic acid anions constitute an alkyl imidazole gallate ionic liquid antioxidant, and the choline cations and gallic acid anions constitute a choline gallate ionic liquid antioxidant. The problems of poor oil solubility and general antioxidant effect of biodiesel antioxidants in the prior art are solved.
