2,3-Dichlorofluorobenzene Usage And Synthesis

Uses

Preparation of 2,3-dichloroanisole: Using 2,3-dichlorofluorobenzene as raw material, the following steps were performed sequentially: 1) 2,3-dichlorofluorobenzene was reacted with sodium methoxide in methanol solution at 20-80℃ for 2-24 h; the molar ratio of sodium methoxide to 2,3-dichlorofluorobenzene in the sodium methoxide in methanol solution was 1-4:1; 2) After cooling, the product obtained in step 1) was filtered, and the filtrate was distilled under reduced pressure to recover methanol, then water was added and stirred. The precipitated white crystals were dried to obtain 2,3-dichloroanisole. The preparation of 2,3-dichloroanisole using the above method conforms to the concept of green chemistry and has the characteristics of high yield.
