| Abstract: | Synthesized the nerolin bromelia (β-naphthyl ethyl ether) from β-naphthol and ethyl alcohol in the presence of sodium bisulfate monohydrate. Investigated the influent factors of reaction and reuse ability of the catalyst. The yield of the ether can reach 90.0% under amount of substance ratio of β-naphthol, ethyl alcohol and sodium bisulfate are 1∶4∶0.44, reflux reacting for 12 h. The result shows that sodium bisulfate can be used as catalyst for the etherification instead of sulfuric acid. Compared the catalytic activity of ferric chloride hexahydrate, stannic chloride pentahydrate and sodium bisulfate monohydrate for synthesis of nerolin bromelia. |
