摘要：NOVELTY - A beta -naphthyl methyl ether synthetic preparation method involves adding bisulfate as catalyst, heating to reflux and continuously distilling methanol. The methanol is dripped. An organic solvent and water are added and stirred until completely dissolving. An organic phase of sodium hydroxide aqueous solution is separated. A water washing organic phase is separated. Anhydrous sodium sulfate is dried. The solvent is evaporated to obtain crude product. The organic solvent is utilized with a certain type re-crystallization to obtain white flaky naphthalene methyl ether. USE - Method for preparing beta -naphthyl methyl ether synthetic. ADVANTAGE - The method enables preparing beta -naphthyl methyl ether synthetic in an inexpensive manner with high yield and without causing environment pollution in real time. DETAILED DESCRIPTION - A beta -naphthyl methyl ether synthetic preparation method involves adding a certain amount of bisulfate as catalyst, heating to reflux and continuously distilling methanol. The methanol is dripped after cooling the mixture to room temperature. An organic solvent and water are added and stirred until completely dissolving. An organic phase of sodium hydroxide aqueous solution is separated. A water washing organic phase is separated. Anhydrous sodium sulfate is dried. The solvent is evaporated to obtain crude product. The organic solvent is utilized with a certain type re-crystallization to obtain white flaky naphthalene methyl ether.
