摘要
将邻硝基氯苯溶于１．６７倍摩尔乙醇中，在相转移催化下于常压、９０℃以下滴加浓碱制得邻硝基苯乙醚（Ⅰ），进而用硫化碱还原Ⅰ并减压蒸馏制成邻氨基苯乙醚。总收率为７２％。
o Nitroethoxybenzene(Ⅰ) is obtained by solving o nitrochlorobenzene in small amount of alcohol and dropping concentrated alkali at atmos below 90℃ with the PTC.Then reducing I to o ethoxyaniline(Ⅱ) with Na 2S and purifying crude Ⅱ by vacuum distillation.The total yield is 72%.
