The application results from fluorination showed microwave heating could accelerate chemical reactions markedly. The reaction time could be shortened 50% at least than that of conventional heating. The relationship between fluorinating agents\' structure and their activity was studied systematically. In addition, an anhydrous KF with higher activity was prepared by using expansion effect of microwave heating. As we known, solvents were very important to reaction. The comprehensive study showed some less polar aromatic solvents could be used as dipolar solvents. In addition, they had better effect than dipolar solvents in some occasions, such as fluorination of chlorobenzaldehydes and chlorinated diphenyl ketones etc. The primary applications of ionic liquids were also studied which indicated reactions with ionic liquids as solvents were more efficient and simple.
研究表明,微波是一种节能高效的加热方式,在微波作用下的卤素交换氟化反应具有反应速度快、转化率高、选择性好的优点,其反应时间可较常规加热缩短50%以上;同时也系统地研究了氟化剂种类及制备方式对其反应活性的影响,并利用微波加热的膨化作用制备出了一种活性较高的KF,其活性与喷雾干燥KF相差不大;溶剂对反应具有重要的作用,在此系统地研究了强极性非质子溶剂和中等极性非质子溶剂的应用情况,发现一些中等极性的非质子溶剂如硝基芳烃和氯代芳烃类溶剂在氯代苯甲醛类化合物的氟化反应中具有比强极性非质子溶剂更好的使用效果。
