| Abstract: | 2,4 -D butylate was synthesized from 2,4 -dichlorophenoxyacetic acid and n -butanol using H4SiW12O40/TiO2 as catalyst. The optimum conditions were obtained by orthogonal experiment as follows： molar ratio of acid to alcohol 1：5, amount of the catalyst 0.15 g （based on 0.04 mol 2,4 - dichlorophenoxyacetic acid）, the volume of cyclohexane as water - carrying agent 8 mL, and reflux reaction time 2 hours. The yield of 2,4 - D butylate can reach 80.78% under above conditions. The product was characterized by IR. |
