| titleOfInvention | Ionic liquid catalyst for synthesizing bio-based polycarbonate and method for synthesizing bio-based polycarbonate |
| abstract | The invention relates to a synthetic bio-based polycarbonAn ionic liquid catalyst of acid ester and a method for synthesizing bio-based polycarbonate. The anion of the ionic liquid catalyst is amino acid anion, and the cation of the ionic liquid catalyst is any one of quaternary ammonium cation, quaternary phosphine cation, imidazole cation, pyridine cation or piperidine cation. The amino acid ionic liquid catalyst has the advantages of environmental protection, biodegradability and low residue; compared with traditional catalysts such as alkali metal salt, alkaline earth metal salt or quaternary ammonium, quaternary phosphonium salt and the like, intermolecular hydrogen bonds formed by the ionic liquid and the isosorbide can break intramolecular hydrogen bonds formed by the internal hydroxyl of the isosorbide, and the activated internal hydroxyl/external hydroxyl of the isosorbide<1, thereby synthesizing (T) with good thermal stability g 174 c) high molecular weight bio-based polycarbonate. |
