| Abstract: | 2,4-Dichloro-5-nitrophenylisopropyl ether was prepared from 2,4-dichloro-5-nitrophenol in the presence of DMF,using potassium carbonate as deacid reagent,adding isopropyl bromide drop wise.Effects of deacid reagent,solvent,temperature,reaction time was investigated.Yield of 2,4-dichloro-5-nitrophenylisopropyl ether 95.5% and purity 95.1% could be gained in the optimized process conditions.The process has advantage on lowering costs,simplifying unit operations,high product purity,and convenience for the implementation of industrialization. |
