Paragraph 0018-0021, (2019/10/04)
The invention provides a green method for synthesizing 2-furylglyoxylic acid, and belongs to the technical field of pharmaceutical chemical processes. The method includes the following steps: (1) adding solvents, furan, chloroacetic acid and Y-type zeolite molecular sieves to a reaction kettle, and carrying out a reaction to obtain 2-furylacetic acid; (2) adding solvents, cobaltosic oxide and 2,2,6,6-tetramethylpiperidine oxide to the obtained 2-furylacetic acid, and injecting oxygen to oxidize the 2-furylacetic acid to obtain the 2-furylglyoxylic acid. The green method for synthesizing the 2-furylglyoxylic acid has the advantages that a raw material used, namely the chloroacetic acid, is cheap and easy to obtain, heterogeneous catalysts, namely the Y-type zeolite molecular sieves and the cobaltosic oxide, are easy to separate and recover and can be recycled, an auxiliary catalyst, namely the 2,2,6,6-tetramethylpiperidine oxide, is beneficial to acceleration and selectivity improvement of oxidation reactions, the oxygen serving as an oxidant is green and environmentally friendly, and accordingly, costs and generated 'three wastes' of the obtained 2-furylglyoxylic acid are greatly reduced; the purity and the yield of the obtained 2-furylglyoxylic acid are respectively higher than 99% and 90%.
