二苯甲醇又称α-苯基苯甲醇,是一种重要的有机中间体。它主要用于合成多种药物,如苯海拉明(抗组胺药)、茶苯海明(乘晕宁、抗组胺药)、赛克利嗪(抗组胺药)、二苯拉林(抗组胺药)、苯甲托品(抗胆碱药)、莫达非尼(抗抑郁药)、桂利嗪(血管扩张药)和阿屈非尼(中枢神经兴奋药)等。
应用二苯甲醇酯是一类重要的化合物,广泛用于多种反应的原料,并合成出各种不同的产物。
制备CN201210422917.1提供的制备方法包括以下步骤:
第一步 S1向反应釜中依次加入60~70%(优选67%,±0.5%)的甲醇、水、片碱和二苯甲酮,以及铝粉。建议的摩尔比例关系为二苯甲酮:铝粉:片碱=1:0.9~1:1.1,最优化的比例为1:0.9:1.1。
阶段S15:当碱浓度为5.4~5.5%时,在反应釜中投入二苯甲酮。均匀搅拌后,降温至47~54℃,保持一段时间(优选在降至47℃后保持5分钟)。
阶段S17:在此温度下,分批多次间隔投放铝粉,每次投放的重量递减且两次投放的时间间隔也递减。务必一勺一勺匀速加入,每批投放时间建议为一分钟。当所有铝粉投入完毕后,将反应釜升温至50~55℃并保持30分钟。
