Na2CO3-NaHCO3混合碱条件下安息香的辅酶合成

Coenzyme Synthesis of Benzoin in Na2CO3-NaHCO3 Mixed Alkali

利用混合碱14%Na2CO3-4%NaHCO3缓冲溶液控制安息香合成中碳负离子形成速度,避免溶液pH值过大或过小,调节乙醇和水溶剂含量,保证反应时溶液均相,提高安息香的产率。实验过程没有使用强碱NaOH,避免了对环境的污染问题。

Mixed base 14%Na2CO3-4%NaHCO3 buffer solution was used to control the formation rate of carbon negative ions in the synthesis test of benzoin,so as to avoid the pH value of the solution being too large or too small,regulate the solvent content of ethanol and water,ensure the homogeneous solution during the reaction,and improve the yield of benzoin.Strong base NaOH was not used in the experiment,which avoided environmental pollution.
