【摘要】：在過(guò)量環(huán)氧氯丙烷中,以季銨鹽為催化劑,在阻聚劑存在的條件下,采用二氯甲烷共沸脫水,相轉(zhuǎn)移催化一鍋法制備了甲基丙烯酸縮水甘油酯�？疾炝朔磻�(yīng)時(shí)間,反應(yīng)溫度,催化劑種類等不同條件對(duì)產(chǎn)物收率的影響。結(jié)果表明,較佳的反應(yīng)條件是:催化劑采用四丁基氯化銨,阻聚劑用量為甲基丙烯酸的1%,環(huán)氧氯丙烷用量為甲基丙烯酸的600%,反應(yīng)溫度80~85℃,反應(yīng)時(shí)間3h。在此條件下,產(chǎn)物GC純度大于98.5%,收率大于89%。
[Abstract]:Glycidyl methacrylate was prepared by using dichloromethane azeotropic dehydration in the presence of polymerization inhibitor and quaternary ammonium salt in excess epichlorohydrin. The results showed that the optimum reaction conditions were as follows: tetra#china_person0# ammonium chloride was used as catalyst, The amount of polymerization inhibitor is 1% of methacrylic acid, the amount of epichlorohydrin is 600% of methacrylic acid, the reaction temperature is 80 鈩，
