在298k时，在牛磺酸钾水溶液中吸收CO2时观察到反应产物的结晶。结晶固体被发现是质子化胺。测定了不同氨基酸盐浓度下发生结晶的临界CO2负荷值。建立了临界CO2负荷值、氨基酸盐初始浓度与氨基酸在水中溶解度之间的简单关系。这种关系似乎在预测除牛磺酸以外的氨基酸盐的临界CO2负荷值方面保持得很好。化学。Res. 1997, 36,1779)最近发表了一些定性实验数据。以搅拌反应器为研究对象，半定量地研究了牛磺酸钾水溶液吸收CO2过程中固相反应产物的形成对气液接触器传质特性的影响。特别是晶体存在和不存在的影响……
Crystallization of a reaction product was observed during the absorption of CO2 in aqueous potassium taurate solutions at 298 K. The crystallizing solid was found to be the protonated amine. The critical CO2 loading value at which crystallization occurred was measured for various amino acid salt concentrations. A simple relation between the critical CO2 loading value, initial amino acid salt concentration, and solubility of the amino acid in water is established. This relation seems to hold well in predicting the critical CO2 loading value for salts of amino acids other than taurine, for which Hook (Ind. Eng. Chem. Res. 1997, 36, 1779) has recently published some qualitative experimental data. The influence of the formation of the solid reaction product during the absorption of CO2 in aqueous potassium taurate solutions on the mass-transfer characteristics of a gas−liquid contactor was investigated semiquantitatively for a stirred reactor. In particular, the effect of the presence and absence of crystals ...
