说明

碳酸铵是一种铵盐。它是无色的,由水溶性立方晶体组成。它可以通过二氧化碳与氨反应合成。它被广泛用作灭火器中的二氧化碳源。[1] 据报道,在 35-80°C 的温度范围内,碳酸铵水溶液中 CO2 吸收焓的量热估计。[2]

碳酸铵可用于通过Biginelli和Hantzsch反应制备3,4-二氢嘧啶-2(1H)-酮和1,4-二氢吡啶衍生物。[3] 它还可以通过尺寸排阻液相色谱和反相液相色谱与质谱联用法积极用作分离、检测和鉴定卵清蛋白和血清白蛋白胰蛋白酶消化物中产生的肽片段的缓冲液。[4]

一般描述

Ammonium carbonate is an ammonium salt. It is colorless and is composed of water soluble cubic crystals. It can be synthesized by reacting carbon dioxide with ammonia. It is widely employed as a CO2 source in fire extinguishers.[1] Calorimetric estimation of enthalpies of absorption of CO2 in aqueous solutions of ammonium carbonate in the temperature range of 35-80°C have been reported.[2]
 

应用

Ammonium carbonate may be employed in the preparation of 3,4-dihydropyrimidin-2(1H)-one and 1,4-dihydropyridine derivatives, via Biginelli and Hantzsch reactions.[3] It can also be actively used as buffer in the separation, detection, and identification of the peptide fragments generated in the tryptic digests of ovalbumin and serum albumin, via size exclusion liquid chromatography and reverse phase liquid chromatography coupled to mass spectrometry.[4]
