摘 要:以双酚A(BPA)和环氧氯丙烷(ECH)为原料,在NaOH作催化剂的条件下合成了双酚A二缩水甘油醚(DGEBA)。考察了w(NaOH)、反应温度、反应时间、n(ECH)/n(BPA)对DGEBA产率的影响。DGEBA的熔点为47.5℃。提高w(NaOH)和n(ECH)/n(BPA),延长反应时间,DGEBA的产率均呈现先增大后减小的趋势;DGEBA产率随着反应温度的升高而降低;当n(ECH)/n(BPA)为10∶1,w(NaOH)为30%,反应温度为75℃,反应时间为170 min时,DGEBA产率可达到80.1%。Diglycidyl ether of bisphenol A(DGEBA) was prepared by using bisphenol A(BPA) and epichlorohydrin(ECH) as raw materials in the catalysis of sodium hydroxide.The effects of the mass fraction of sodium hydroxide,reaction temperature and time as well as molar ratio of ECH to BPA on DGEBA yield were investigated.The melting point of DGEBA was 47.5 ℃.The DGEBA yield had a tendency to increase first and then decrease with increasing the mass fraction of sodium hydroxide,molar ratio of ECH to BPA and reaction time,while the yield decreased with the rise in the reaction temperature.The yield of DGEBA reached 80.1% when the molar ratio of ECH to BPA was10∶1,mass fraction of sodium hydroxide was 30%,reaction temperature was 75 ℃ and reaction time was 170 min.
