Catalytic synthesis of β-naphthol methyl ether with tin tetrachloride

β-naphthol methyl ether was catalytically synthesized by tin tetrachloride. The effects of the dosage of methanol and SnCl_4·5H_2O, reaction time on the yield of β-naphthol methyl ether were studied. When the amount of β-naphthol was 1.8 g, methanol was 1.5 mL, SnCl_4·5H_2O was 0.33 g, 80℃ reacted for 10 h,the yield of β-naphthol methyl ether may up to 75.3%.
