【Abstract】 β-naphthol butyl ether was directly synthesized from β-naphthol and n-butyl bromide using the dimethyl sulphoxide(DMSO) as solvent under microwave irradiation.By a single factor test,effects of ratio between reactants,microwave power,irradiation time et al on reaction yield were examined.The experimental results showed that microwave irradiation can enhance the yield of βnaphthol butyl ether.Optimal reaction conditions were determined as follows: (n(β-naphthol),)n(potassium hydroxide) and n(n-butyl bromide) is 0.018 mol,0.022 mol and 0.018 mol,respectively.Account of dimethyl sulphoxide used is 20 mL.Microwave power is 520 W.Irradiation time is 35 s.Yield of β-naphthol butyl ether achieves 96.1%.更多还原
