    • Synthesis of ACETIC ANHYDRIDE

      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.

      Acetic anhydride is the only monocarboxylic acid anhydride that is important in modification reactions. The acetylation of the amino groups of proteins can be made relatively specific if the reaction is carried out in saturated sodium acetate, since the O -acetyltyrosine derivative is unstable to an excess of acetate ions ( Fraenkel-Conrat, 1959 ).
