General description
氢氧化钾是一种强碱，可用于亲核取代反应、加成反应和碱性水解反应。它也可以用来催化醛型反应。
Application
氢氧化钾可作为碱用于：
- 芳基卤化物与烯烃的 Pd 催化 Heck 反应。
- 通过夹镍催化 Guerbet 反应合成 β-烷基化醇。
- 用于芳基或杂芳基硼酸到相应酚的羟基化反应。
- 甘油三酯酯交换反应，以制备生物柴油。
- 通过芳胺与苯乙烯的分子间加成合成 β-苯基乙胺。
- Claisen-Schmidt 缩合反应，以合成查尔酮。
Packaging
本品也可用玻璃瓶包装。

We demonstrate a novel technique to fabricate sub-micron silicon nitride waveguides using conventional contact lithography with MEMS-grade photomasks. Potassium hydroxide anisotropic etching of silicon facilitates line reduction and roughness smoothing and is key to the technique. The fabricated waveguides is
