一般說明

氢氧化钾(KOH)是吸湿性水溶性碱,通过电解氯化钾溶液合成。它是合成许多钾化合物的原料。KOH可与CO2反应形成碳酸钾。该性质可用于吸收CO2它作为催化剂参与醛醇缩合反应。硅的KOH各向异性蚀刻可用于使用常规接触光蚀刻制造亚微米氮化硅波导。KOH粉末可用于制备查耳酮。

應用

氢氧化钾(KOH)用于以下过程:
  • HPLC法定量检测生物样品中的谷胱甘肽(GSH)和谷胱甘肽二硫化物(GSSG)。
  • 制备缓冲液用于种子脂肪酸(FA)组成、蛋白、油和糖含量的研究 。
  • 秀丽隐杆线虫的稳定同位素分析研究。
氢氧化钾可用作激光改性玻璃的蚀刻剂。它可与碲粉末联合介导芳族羰基化合物的定量频哪醇化。
