摘　　要：在一个反应器内 ,在盐酸催化剂存在下 ,先后进行淀粉水解反应生成葡萄糖 ,葡萄糖脱水生成 5 -羟甲基糠醛 ,再与苯酚反应生成热塑性酚醛树脂。讨论了操作条件对树脂产率及熔点的影响 ,获得了最佳工艺条件 ,并用红外光谱对产品进行了认证。In the presence of hydrochloric acid ,glucose was synhesized by the hydrolysis of starch,5-methylolyfurat was synthesized by the dehydration of glucose ,novolak was synthesized by 5-methylolfurfural with phenol,in one pot.The effects of operating conditions on resin yield and melting point were discussed and the optimum conditions were obtained .The results of IR spectrometry indicate that the synthesized product is phenolic resin.
