epichlorohydrin of some natural phenolic compounds such as 4-methylcatechol, gallic acid, protocatechuic acid, pyrogallol and resorcinol was investigated. Phenolic compounds reacted first with epichlorohydrin in the presence of benzyltriethylammonium chloride as phase transfer catalyst. Then, an aqueous solution of sodium hydroxide was added. It was demonstrated that the two competitive mechanisms involved in
研究了环氧氯丙烷对某些天然酚类化合物(如4-甲基邻苯二酚,没食子酸,原儿茶酸,邻苯三酚和间苯二酚)的O-烷基化反应。在苄基三乙基氯化铵作为相转移催化剂的存在下,酚类化合物首先与环氧氯丙烷反应。然后,加入氢氧化钠水溶液。 已经证明,参与O-烷基化反应的两个竞争机制高度依赖于起始原料。在该反应中获得的O-烷基化产物可以进一步用作环氧树脂预聚物的合成中的双酚A替代物。
