摘要
In this paper,the dibenzo-14-crown-4(DB14C4,abbreviation of Dibenzo-14-crown-4) is synthesized by the ultrasonic synthesis method when use 1,3-dibromopropane and pyrocatechol as starting material,dimethyl sulfoxide(DMSO) as solvent,and lithium hydroxide as catalyst and template reagent.The experiment result shows that the new synthetic method has some properties such as simple operation(no protection of nitrogen gas),short reaction time(50min),high yield(42.2%),etc.and it is a extensive new method for synthesis of crown.
In this paper,the dibenzo-14-crown-4 （ DB14CA, abbreviation of Dibenzo-14-crown-4） is synthesized by the ultrasonic synthesis method when use 1,3-dibromopropane and pyrocatechol as starting material, dimethyl sulfoxide（DMSO） as solvent, and lithium hydroxide as catalyst and template reagent. The experiment result shows that the new synthetic method has some properties such as simple operation （ no protection of nitrogen gas ）, short reaction time （ 50min）, high yield （42. 2% ） , etc. and it is a extensive new method for synthesis of crown.
