Benzene hydroxyl anion functionalized ionic liquid antioxidant and preparation method thereof |
| abstract |
The invention relates to a phenylhydroxy anion functionalized ionic liquid antioxidant and a preparation method thereof, belonging to the technical field of biodiesel antioxidants. The hydroxyl anion functionalized ionic liquid antioxidant consists of alkyl imidazole cations or choline cations and gallic acid anions, wherein the alkyl imidazole cations and the gallic acid anions form alkyl imidazole gallate ionic liquid antioxidants, and the choline cations and the gallic acid anions form choline gallate ionic liquid antioxidants. The invention solves the problems of poor oil solubility and common antioxidant effect of the antioxidant of the biodiesel in the prior art. |
