说明

General description

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。

Application

醋酸钾用作催化剂：

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 E₂E2 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。

Comparison of alkaline lysis with electroextraction and optimization of electric pulses to extract plasmid DNA from Escherichia coli.

Saša Haberl et al.

The Journal of membrane biology, 246(11), 861-867 (2013-07-09)

The use of plasmid DNA (pDNA) as a pharmaceutical tool has increased since it represents a safer vector for gene transfer compared to viral vectors. Different pDNA extraction methods have been described; among them is alkaline lysis, currently the most

Structural correlates of cytoplasmic and chloroplast lipid body synthesis in Chlamydomonas reinhardtii and stimulation of lipid body production with acetate boost.

Carrie Goodson et al.

Eukaryotic cell, 10(12), 1592-1606 (2011-11-01)

Light microscopy and deep-etch electron microscopy were used to visualize triacylglyceride (TAG)-filled lipid bodies (LBs) of the green eukaryotic soil alga Chlamydomonas reinhardtii, a model organism for biodiesel production. Cells growing in nitrogen-replete media contain small cytoplasmic lipid bodies (α-cyto-LBs)
