Question

Acetic anhydride from sodium ethanoatee

Answer 1

Answer:

The crude distillate is finally purified by second distillation (boiling point of acetic anhydride is 138 °C) with 3 grams of finely pulverized anhydrous sodium acetate, which serves to convert the last portions of acetyl chloride into the acetic anhydride. The yield of acetic anhydride is about 50 grams.
