For the synthesis of benzyl ether, 350kg water was added to the reactor, and 150kg NaOH was added under stirring. After dissolution, cool down to 10 ℃, add 110kg resorcinol and stir to dissolve. Then 126 kg dimethyl sulfate was slowly added and reacted at 26 ~ 30 ℃ for 2 hours. Dilute with water, separate the oil layer, and wash the oil layer to neutral with water. Remove the low Buddha point, distill and collect the fraction at 215 ~ 220 ℃, which is m-phenyldimethyl ether.
