在基础有机化学实验课中,为了缩短实验时间,减少药品用量,加强学生的操作训练,我们用半微量法将二苯甲酮还原为二苯甲醇。二苯甲酮的还原,可以使用多种还原剂,如:锌—碱,硼氢化钠,氢化铝锂等。我们将锌—碱还原的方法改成半微量,学生可在四小时内完成实验。 In the basic organic chemistry experiment class, in order to shorten the experimental time, reduce the amount of drugs, to enhance students’ training, we use a semi-micro method to reduce benzophenone into benzhydrol. Benzophenone reduction, you can use a variety of reducing agents, such as: zinc - alkali, sodium borohydride, lithium aluminum hydride and so on. We changed the zinc-alkali method to a semi-trace and students completed the experiment in four hours.
