General description

氢氧化钾（KOH）又称苛性钾。它被用作许多含钾产品的重要前体。

Application

与碲粉结合，介导芳香族羰基化合物的吡那酮化反应。
氢氧化钾可用于：
  • 作为碱，从胺和乙醇合成亚胺。
  • 作为仲醇与伯醇β-烷基化反应的碱，无需任何过渡金属催化剂。
  • 结合铝用于芳香醛的吡啶化和受阻酮的还原。
  • 作为沉淀剂，采用改性水热法制备 MnZn 铁氧体纳米粒子（Mn0.8Zn0.2Fe2O4铁氧体纳米粒子）。

The effect of the alkali-metal cation (Li+, Na+, K+, and Cs+) on the non-Nernstian pH shift of the Pt(554) and Pt(533) step-associated voltammetric peak is elucidated over a wide pH window (1-13), through computation and experiment. In conjunction with our

The extracellular matrix (ECM) is a complex, spatially inhomogeneous environment that is host to myriad cell-receptor interactions that promote changes in cell behavior. These biological systems can be probed and simulated with engineered surfaces, but doing so demands careful control
