Abstract:2,7-dimethoxynaphthalene was prepared from 2,7-dihydroxynaphthalene and dimethyl sulfate. The effects on the reaction were also discussed. Under the reaction conditions as follows: n(2,7-dihydroxynaphthalene0∶n(doimethylSulfate)=1∶3, reaction temperature of 80℃, reaction time of 3h and by means of dropwise of dimethylsulfate, the yield of 2,7-dimethoxynapthalene was up to 783%.
Key words:2; 7-dimethoxynaphthalene; 7-dihydroxynaphthalene; dimethylsulfate
