| Abstract: | 2,6 - Dichlorophenyl benzyl ether was synthesized using 2,6 - dichlorophenol and benzyl chloride as raw materials in KOH/CH30H solution. The effects of molar ratio of 2,6- dichlorophenol to benzyl chloride, molar ratio of 2,6 - dichlorophenol to alkali, dosage of solvent and reaction time on the yield of product were examined. The result showed that the yield and purity of the product were 83.6% and 97.5% respectively under optimum conditions as follows： n（2,6- dichlorophenol） ： n（KOH） = 1：1.1, n（2,6 - dichlorophenol） ： n （benzyl chloride） = 1：1.2, dosage of CH30H as solvent 60 mL（based on 0.1 mol 2,6- dichlorophenol）, reaction temperature 70 ℃, reaction time 4 hours. The melt point of product was 44 ℃. |
