产品描述

碳酸钾倍半水合物的晶体属于单斜晶系,空间群为C2 / c。
碳酸钾倍半水合物可用作吸附剂,用于在预燃烧过程中从烟道气中去除CO2。 在沉积的Pd催化剂存在下,可将其用作苯硼酸与苯甲酰氯交叉偶联的碱,得到二苯甲酮。

在以下制备中,它也可用作反应成分之一:
•1,2,3-三乙基咪唑鎓
•1,2,3-三乙基-4-甲基咪唑
•2-乙基-1,3,4-三甲基咪唑

General description

Crystals of potassium carbonate sesquihydrate belong to the monoclinic crystal system and space group C2/c.[1]

Application

Potassium carbonate sesquihydrate can be used as a sorbent for the removal of COfrom flue gas in precombustion process.[1] It may be employed as a base in the cross-coupling of benzene boronic acid with benzoyl chloride in the presence of deposited Pd catalysts to give benzophenone.[2]

It may also be used as one of the reaction components in the preparation of:
• 1,2,3-triethylimidazolium[3]
• 1,2,3-triethyl-4-methylimidazolium[3]
• 2-ethyl-1,3,4-trimethylimidazolium[4]
