一般描述
醋酸钾是一种吸湿性钾盐。它可以通过用氢氧化钾或碳酸钾中和乙酸来制备。它可以作为聚合和加成反应的亲核催化剂，在取代和加成反应中作为醋酸阴离子的来源。它可以在各种有机反应中用作碱和促进剂。
应用
醋酸钾用作催化剂：
醋酸钾也用作促进剂：
- 以糠醛和棕榈酸酐为原料制备 2-十六烷基呋喃。
- 醋酸钾可用作碱：羟肟酸到氨基甲酸的 Lossen 重排。
- In E2 E2 消除反应。
- 从烷氧基酰胺底物形成内酯。
醋酸钾也用作促进剂：
- 钯催化剂环境下芳基氯化物与双(频哪醇合)二硼的硼化反应。
- α, β-不饱和酮的 β-硼化。

Potassium glutamate accumulates upon hyper-osmotic shock and serves as a temporary osmoprotectant. This salt leads to transcriptional activation of sets of genes that allow the cell to achieve long-term adaptation to high osmolarity. The current experiments show that potassium glutamate
