【摘要】 采用超声波技术,以对羟基苯乙酮和4-N,N-二甲基苯甲醛为原料,HCl气体为催化剂,乙醇为溶剂,合成了具有光敏性的N,N-二甲基-4’-羟基査尔酮,产物结构经1H-NMR、FT-IR和UV-Vis等进行了确认.结果表明:超声输出功率400 W,30℃下进行反应30 min产率最高,可达80.1%.故该方法有反应时间短、反应条件温和、产率高等优点.更多还原

【Abstract】 Photosensitive N,N-dimethyl- 4’-hydroxy chalcone was synthesized from p-hydroxyacetophenone and 4-N,Ndimethyl benzaldehyde using ethanol as solvent and dry HCl( gas) as catalyst. The structure of the product was confirmed by1H-NMR,IR and UV-vis spectra. The results indicated that the yield reached the highest value of 80. 1% at 30℃,under ultrasonic output power of 400 W for 30 min. The prominent feature of the present method included short reaction time,mild reaction condition,and high yield.更多还原
