Abstract：A novel synthesis of 2 (2,4 dichlorophenoxy) triethylamine was investigated. 2 (2,4 dichlorophenoxy) triethylamine was prepared by phase transfer catalyst from 2,4 dichlorophenol. The yield of reaction was above 80%. The effects of some factors such as reactants ratio, catalysts, reacting time and temperature etc, were discussed. The structure of product was confirmed by elemental analysis, IR and 1 HNMR.

Key words：2; 4-dichlorophenol; Bu_4NBr; 2-（2; 4-dichlorophenoxy）triethylamine
