摘要
在超声波辐射下,以活性炭负载浓硫酸作催化剂,催化合成了β-萘甲醚。考察了超声波辐射功率、辐射时间、无水甲醇用量、催化剂用量等因素对合成工艺的影响。确定了最佳反应条件:n(β-萘酚)∶n(无水甲醇)=1∶6,x(催化剂)=7%,超声波辐射功率200W,反应时间为15min,反应温度为80℃,在该条件下,β-萘甲醚产率为98.3%。该方法条件温和、操作简便高效。
β-Naphthyl methyl ether was synthesized in the presence of a new kind of the cheap and effective environmental friendly solid catalyst H2SO4/Carbon under the ultrasonic irradiation.The influences of catalyst's dosage,methanol consumption,reaction time and ultrasonic power on the yield of product have been investigated.The optimal reaction conditions are as follow:the mole ratio of β-naphthol and methanol is 1:6,catalyst molar fraction is 7%,ultrasonic power is 200 W,reaction time is 15 min and temperature is 80 ℃.Under the optimal reaction condition,the yield of β-naphthyl methyl ether is 98.3%.The reaction condition is mild.The method is simple and efficient.
