Using o-dihydroxybenzene and 1,11-dichloro-3,6,9-trioxaundecane as raw materials,sodium hydroxide as template,DMF as solvent and appropriate amount of 2,6-di-tert-butyl-4-methylphenol as antioxidant,benzo-15-crown-5 was successfully synthesized under ultrasonication at temperature 60~70℃.Compared with traditional synthetic routes,reaction time could be reduced to within 2 h,and the yield reached up to 30.7%.
