A practical synthesis of the cyclic butylene terephthalate trimer

This paper described a practical synthetic approach for the cyclic butylene terephthalate trimer (7). The key step was a ring-closing metathesis, using Grubbs' second-generation catalyst to form the macrocyclic ring. The advantages of this procedure included short reaction steps, simple operations and good yields.

Preparation method of cyclic polyester oligomer

The invention relates to a preparation method of cyclic polyester oligomer and belongs to the technical field of organic synthesis. According to the preparation method, a terephthalic acid derivative and a dihydric alcohol are adopted as raw materials. The raw materials are subjected to condensation reaction through the liquid-liquid interface phase transfer process, and then the cyclic polyester oligomer can be obtained. Compared with the conventional depolymerization cyclization method, the terephthalic acid derivative and the dihydric alcohol are adopted as raw materials. In the presence of a catalyst, a target product is synthesized through controlling the dropping speed. Therefore, the synthetic method is simple and easy to operate, and has a very high industrial application value.
