Summary:As an important platform compound, the 3-acetamido-5-acetyl furan plays a crucial role in sustainable production of nitrogen-containing fine chemicals. The invention discloses a method for catalytically degrading chitin monomer Nacetylglucosamine by using choline chloride eutectic solvent, which uses choline chloride eutectic solvent as a catalyst and comprises the following steps: adding a smallamount of chloride and boric acid as cocatalysts and N, N-dimethyl acetamide as a solvent at a certain temperature, and refluxing at normal pressure for 60 minutes, and converting the Nacetylglucosamine to obtain the 3-acetamido-5-acetyl furan. The reaction system is simple in method, green and environment-friendly, and the used raw materials are low in price. In addition, the synthesis method ofthe eutectic solvent is also very simple and easy to operate. The choline chloride is easy to obtain and renewable, the pollution to the environment can be greatly reduced by using the choline chloride, and meanwhile, great ec
