Abstract:

A new route is put forward to prepare 1,3-bis(p-carboxyphenoxy) propane,which is the key intermediate for synthesizing polyanhydride in order to increase yield and purity.1,3-bis(p-carboxyphenoxy) propane is prepared using phase transfer catalyst from ethyl 4-hydroxybenzoate.Compared to the traditional ways,the yield can be doubled(93.2%....More
