General description

碘化钾是一种水溶性无机盐，可通过氢碘酸与碳酸氢钾反应来制备。

Redi-Dri™ 技术消除了结块，也不需要复杂的程序来保持盐的自由流动。保持盐干燥有助于改进结果，提供准确的测量和更容易处理的盐和缓冲液。Redi-Dri™ 不需要在烤箱或干燥器中干燥盐，也不需要手动将盐分开，可以确保盐在几个月内保持易于使用，而无需担心防结块剂。即使在反复打开后，你也可以确信你的结果总是准确的。Redi-Dri™ 可以节省你的时间、精力和金钱，让你的盐可以使用更长时间!

Application

碘化钾可用作以下反应的催化剂：
  • 以叔丁基过氧化氢作为氧化剂时，芳族伯胺转化成相应的硝基化合物。
  • 在镍催化剂存在下，芳基卤转化为芳基碘。
  • 在8-冠-6和叔丁基过氧化氢存在下，通过活化烯烃和磺酰肼在水中反应而制备磺化羟吲哚。

Features and Benefits

  • 提高效率——免除需要松散硬化粉末的时间和精力
  • 更加安全——避免使用工具大力敲碎团块的风险
  • 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
