摘要:在酸性或碱性懽化条件下,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各了酸催化或碱催化环氧大豆油改性酚醛树脂(PF)。利用液相色谐一质谱联用技术对
合成的环氧大豆油改性阶类产物进行分析,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

Abstract 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(P) 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 eact 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 omparing with acid a al c 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
Keywords: liquid chromatography-mass spectrometry technology; phenol formaldehyde resin epoxidized soybean oil
