| Abstract: | Dibenzo-18-crown-6（DB18C6） is synthesized by ultrasonic synthetic method using pyrocatechol ,diglycol and 4-toluenesulfonyl chloride as startmg marerlals, using and using potassium hydroxide as catalyst and template reagent. The product was characterizede by IR and ^1 H NMR. The experiment result shows that the new synthetic method has some better properties than traditional methods have, such as mild reaction conditions （no protection of nitrogen gas） .short reaction time （1.5h） .high yield （42%） ,etc. and it is a new method for synthesis of crown. |
