产品介绍：碳酸钾是一种无机碱。作为碱参与 palladacycle 催化的氯苯与苯乙烯的 Heck 反应。向 K2CO3（溶剂）中加入氨基酸（甘氨酸、肌氨酸和脯氨酸）可促进 CO2 的吸收。应用碳酸钾被用于制备双磺化双（4-（3-氨基苯氧基）苯基）砜（一种二磺化二胺单体）。它可用于以下研究作为合成多取代碘苯衍生物的试剂。作为合成由各种双酚衍生的高分子量均聚物和共聚物的基础。作为芳基卤化物与芳基硼酸的 Suzuki 偶联的碱基。苯乙烯和溴苯的 Heck 反应。 Potassium carbonate can be used for deproteinization. Mild drying agent where other drying agents such as calcium chloride and magnesium sulfate may be incompatible. Not suitable for acidic compounds, but can be useful for drying an organic phase if one has a small amount of acidic impurity. Potassium carbonate is also used in the synthesis of well-defined phosphate-methylated DNA fragments It is shown that base deprotection can be accomplished in potassium carbonate/methanol without affecting the methyl phosphotriestersA potassium salt for deproteinization and as a drying agent
