摘要
以2,6-二羟基萘为原料,硫酸二甲酯为甲基化剂,在氢氧化钠水溶液中,制备2,6-二甲氧基萘,产品经提纯后为白色结晶,熔点为155～156℃,纯度大于99%,总收率大于85%。
2,6-Dimethoxynaphthalene is synthesized with 2,6-dihydroxynaphthalene as raw material , dimethyl sulfate as methylation agent and in aqueous solution of sodium hydroxide. The crude product is refined to get a product of white crystal with purity over 99% and melting point 155～156℃,the yield is over 85%.
