摘　　要：研究了一种以糠醛为原料,盐酸硫胺素（VB1）为催化剂,在pH为9-10的碱性条件下,采用安息香缩合反应合成糠偶姻。考察了反应温度、反应时间、催化剂质量对收率的影响,确定合成工艺的最佳条件为：反应温度65℃,反应时间2.0 h,VB18.0 g,收率达到82.7%。产物为白色针状晶体,熔点为138-139℃,产品结构用红外光谱、元素分析方法进行表征。Using furfural as raw material and VB1 as catalyst preparation of furoin was studied through benzoin condensation in the alkaline condition, pH of 9 to 10. The effect of reaction temperature, reaction time and the amount of VB1 were investigated. The optimum reaction conditions are as follows： reaction temperature： 65 ℃, reaction time： 2 h, the amount of VB1 ： 8. 0 g. The yield of the product reached 82.7 %. The product is white needle-like crystals with the melting point of 138 139 ℃. Structure of objective product was characterized on IR and elementary analyses.
