Preparation of Sodium Diacetate

Abstract

The sodium diacetate using acetic acid and sodium hydroxide as materials was prepared in which one-step liquid-phase method and microwave method were adopted in the paper. By single factor experiment, the regularities of the influence of various factors including reaction temperature, reaction time and acetic acid-sodium hydroxide ratio on the yield of sodium diacetate were studied. Through the orthogonal experiment the optimum synthesis conditions of sodium diacetate were confirmed that the reaction temperature was 70°C, the reaction time was 60min and the acetic acid-sodium hydroxide ratio was 2.1:1. The product yield was 96.2% under the optimal reaction conditions.
