1.what is of  Dibenzo-18-crown-6 with CAS 14187-32-7?

Dibenzo-18-crown-6 is the raw material for the synthesis of diaminodibenzo-18-crown-6. Diaminodibenzo-18-crown-6 is an important crown ether compound and an important intermediate raw material for the synthesis of crown ether derivatives. Its synthesis method is to use dibenzo-18-crown-6 as a raw material, and to obtain it through nitration and reduction reaction. The reduction method used is Pd/C reduction method, which is limited by the expensive catalyst price. The traditional synthesis method of dibenzo-18-crown-6, the raw material of diaminodibenzo-18-crown-6, is a reflux reaction under nitrogen protection, which has harsh conditions, complicated steps, long reaction cycle, high temperature and low yield. Ultrasonic synthesis is a new type of synthesis method developed in recent years. It has the advantages of good directionality, large energy and strong penetration ability. It is more convenient and easy to operate than traditional organic synthesis methods. The experimental equipment is also relatively simple and easy to control. It is more and more widely used in organic synthesis.
