一般描述

醋酸钾（KOAc）是醋酸的钾盐。它通常用作有机合成中各种反应的碱，包括羟肟酸的 Lossen 重排、E2 消除、醇的去质子化、过渡金属催化反应和裂解反应。此外，KOAc 还用作加成反应和聚合反应的亲核催化剂。

应用

醋酸钾可用作活化剂活化碳材料。

特点和优势

  • 提高效率——免除需要松散硬化粉末的时间和精力     
  • 更加安全——无需使用工具大力敲碎团块
  • 更加环保——不会粘在包装上，减少了浪费     
  • 更加经济——制备和溶剂化速度更快，提高效率并节约成本      
  • 质量保证——经过专业检测的出色品质，无抗结剂添加     
  • 灵活的用量选择——有从研究到放大级别的用量规格可供选择。
