| 摘要: |
| 报道了以糠醛为原料在温和条件下经两步合成出β-（2-呋喃）丙酸乙酯的方法。通过正交试验找出了糠醛和乙酯经缩合反应生成β-（2-呋喃）丙稀酸乙酯的最佳反应温度（-15～－10 ℃）、糠醛滴加时间（2.5 h）和乙醇用量（1.0 mL)。同时通过改用Raney Ni作催化剂使β-（2-呋喃）丙稀酸乙酯能在室温常压下催化氢化成β-（2-呋喃）丙酸乙酯，产率为95％。 |

| Abstract: |
| Starting from furfural,a mild method for the synthesis of ethyl β-(2-furyl) propionate in two steps was reported.By orthogonal tests,the optimum reaction temperature (-15 to －10 ℃),furfural dropping time (2.5 h) and ethanol amout (1.0 mL) in preparation of ethyl β-(2-furyl) acrylate from furfural and ethyl acetate were found out.Ethyl β-(2-furyl) acylate were hydrogenated with Raney Ni to 95% ethyl β-(2-furyl) propionate at room temperatur and atmospheric pressure. |
