| Abstract: | Purification of diphenyl ether by crystallization without solvent is discussed. This method has provided with the characteristics of high efficiency, economy and cleanness. The crystallizing point of the product prepared by this method rises from 26.55°C of the raw material to higher than 26.85°C, and phenol can not be detected in the product by the national standard method. Thus, the object of preparation of diphenyl ether with high crystallizing point and low phenol content has been achieved. |
