摘要
以糠醛为原料，VB1为催化剂，采用安息香缩合反应合成糠偶姻，并利用硫酸铜-吡啶氧化其为糠偶酰．给出较好的实验条件，使合成糠偶酰的产率从37％提高到90％．利用元素分析、GC－Mass联用、IR和UV谱等手段，对所合成的糠偶姻及糠偶酰进行分析表征.
In this experiment, we used the benzoin condensation to synthesize furoin with furfural as raw material in the presence of VB1 as a catalyst. Furoin was oxidized to furil by CuSO4-C5H5N as an oxidant. The better test conditions were found out for increasing the yield of furil synthesized from 37% to 90%, Synthesized furoin and furil were characterized by means of elementary analysis, GCMass spectrum, IR and UV spectrum.
