摘要
在微波辐射下,以2-萘酚、氢氧化钠和氯乙酸为原料合成了2-萘氧乙酸。考察了反应物的摩尔比、微波功率、辐射时间等因素对反应的影响,实验结果表明,当2-萘酚、氢氧化钠和氯乙酸的摩尔比为1∶1.7∶2.0,微波功率为320W、辐射时间为5min时,2-萘氧乙酸的收率为67.7%。
2-Naphthoxyacetic acid was synthesized from 2-naphthol, sodium hydroxide and chloroacetic acid under the microwave radiation. Structures of products were identified by means of micro-melting point measuring instrument and IR. By a single factor test, effects of reactants ratio, microwave power and irradiation time etc. on reaction were studied. Under optimal reaction conditions ： n （2-naphthol） ： n （sodium hydroxide）：n （chloroacetic acid）=1 ： 1.7 ： 2.0, microwave power 320 W and irradiation time 5 min, yield of 2-naphthoxyacetic acid reached 67.7 %.
