在酸性或碱性催化条件下，先将环氧大豆油与苯酚及双酚A反应，合成环氧大豆油改性酚类产物，然后将该产物与甲醛水溶液反应制备了酸催化或碱催化环氧大豆油改性酚醛树脂(PF)。利用液相色谱-质谱联用技术对合成的环氧大豆油改性酚类产物进行分析，发现在酸性催化条件下苯酚和双酚A均与环氧大豆油发生了反应，在碱性催化条件下双酚A更易与环氧大豆油发生反应。傅立叶变换红外光谱分析结果表明，两种催化条件下合成的环氧大豆油改性酚类产物均可与甲醛反应生成具有体型结构的环氧大豆油改性PF。相对于酸催化环氧大豆油改性PF，碱催化的耐热性更好，拉伸强度更高。

Under the conditions of acid catalysis or alkaline catalysis,the epoxidized soybean oil modified phenolic compounds was synthesized by using epoxidized soybean oil to react with phenol and bisphenol A,then acid catalytic or alkaline catalytic epoxidized soybean oil modified phenol formaldehyde resin (PF) was prepared through the reaction of the compounds and formaldehyde solution. The compounds were analyzed by the liquid phase chromatography-mass spectrometry technology. From the analysis results,it is gained that phenol and bisphenol A all react with epoxidized soybean oil under the conditions of acid catalysis but bisphenol A is more easy to react with epoxidized soybean oil under the conditions of alkaline catalysis. FTIR analysis results show that the compounds synthesized under the two catalysis conditions all can react with formaldehyde for shaping epoxidized soybean oil modified PF with the body conformation. Comparing with acid catalytic epoxidized soybean oil modified PF,the heat resistance of the alkaline catalytic epoxidized soybean oil modified PF is better and the tensile strength is higher.
