Abstract:Dichloro-3-ethyl-6-nitrophenol which is the important intermediate to form developer in color photograph was prepared, using p-nitroethylbenzene as the start material .Through TCIA chlorination ,alkalization, and acidification reaction, the target product was gain with high purity(99%), high yield, and low costs. The amount of the chlorination agent charged into the reaction and preparation process can be controlled easily.
Key words:dichloro-3-ethyl-6-nitrophenol; color developer; organic synthesis; TCIA; chlorination agent
