1,2-Diphenoxyethane (DPE) has attracted much attention as a new type of heat-sensitive material sensitizer and a potential polyolefin catalyst additive.

Only a few literatures have reported the synthesis of 1,2-diphenoxyethane, which is mainly prepared by reacting phenol with 1,2-dichloroethane or ethylene glycol sulfonate as starting materials in alkaline water or ethanol medium.
The yield is reported to be as high as 80%, but the product contains more impurities.
The synthesized crude product needs to be purified by high-temperature distillation (collection temperature is about 200ºC, vacuum degree is below 700PChemicalbooka).
This process consumes a lot of energy, and because of the high freezing point of the product, it is easy to block the pipeline, which puts high demands on the equipment.
There are also reports of synthesizing 1,2-diphenoxyethane using 1,2-dibromoethane and phenol as raw materials and ethanol as the solvent, but the yield is only 30%.
Prone to side reactions to convert into vinyl bromide, resulting in low yield
