General description

氢氧化钾是一种无机盐，主要用作合成乙酸钾、 碳酸氢钾和碳酸钾等其他钾化合物的前体。在商业规模上，它是通过氯化钾的电解而合成的。

Application

氢氧化钾可用于以下过程：
  • 在 叔丁醇中将腈转化为酰胺。
  • 芳基卤与不同的含硫、氧和氮的亲核试剂在二甲亚砜中的交叉偶联反应。
  • 作为从玉米棒中制备活性炭的活化剂。
  • 作为碱，用于使氮杂环在聚乙二醇-醚溶剂中发生 N-烷基化反应。
  • 从(S)-苯丙氨醇合成(S)-1-(4-苄基-2-硫代噻唑-3-基）丙-1-酮。
  • 催化环氧丙烷的聚合反应。
Redi-Dri™ is an innovative packaging product line that helps eliminate clumping material by adding extra packaging process steps without any chemical additives, anti-clumping agents, or hydrophobic compounds. Redi-Dri™ offers a more convenient and safer way to handle the products.
