Paragraph 0155-0179, (2017/01/19)
The invention provides a preparation method of 4,4'-dialkoxy methyl diphenyl ether. The method comprises the following steps: conducting a bromination reaction of bromine, 4,4'-dimethyl diphenyl ether and an initiator in an organic solvent to obtain a brominated product; cooling the brominated product with sodium alcoholate to obtain an etherification reaction system; and heating the etherification reaction system for an etherification reaction to obtain the 4,4'-dialkoxy methyl diphenyl ether. Compared with the prior art, the preparation method provided by the invention can greatly increase the product purity on the premise of guaranteeing the yield. The result of the embodiment of the invention indicates that the yield of 4,4'-dialkoxy methyl diphenyl ether prepared by the method is over 50%, and the product purity is higher than 99.5%.
