摘要
利用ＶＢ１催化合成糠偶姻，对ＶＢ１用量、反应温度、氢氧化钠浓度等因素对反应的影响进行了探讨，用ｍｐ、ＵＶＶｉｓ、ＩＲ和１ＨＮＭＲ对产物进行了确证。实验表明，ＮａＯＨ浓度为３ｍｏｌ／Ｌ时可常温反应，产率可提高至８７８％。
The synthesis of furoin with V B1 as catalyst was studied.The effect factors of amount of V B1 , C NaOH and reaction temperature were discussde.It was characterized by means of mp,UV Vis,IR, 1 HNMR spectra.The experimental results showed C NaOH =3mol/L and at room temperature the yield is 87.8%
