Abstract
Using o-dihydroxybenzene and ethanol as raw materials, 2-ethoxy-4-nitro-phenol was synthesized through substitution and nitration reaction firstly, and then crude 2-ethoxy-4-amino-phenol was prepared through Pd/C catalytic hydrogenation of 2-ethoxy-4-nitro-phenol. And the final pure 2-ethoxy-4-amino-phenol product was obtained by recrystallizaion of crude compound with benzene/petroleum ether. Total yield of 60.5% was achieved.
