Abstract:
The highly selective chemical reaction of carbon dioxide with organic amines is considered to a mature technology and a feasible initial path for carbon capture. In order to solve the disadvantages of high volatility, equipment corrosion and high energy consumption of traditional organic amines, amine alcohol "mixture based" solution has been developed and showed excellent carbon dioxide absorption capacity, which is due to the positive effect of intermolecular interaction in amine alcohol "mixture based" solution system on thermodynamic properties. However, the influencing factors of the intermolecular force in multicomponent solution system are complex, including the chemical, physical, structural effects. Therefore, it is necessary to comprehensively use a variety of characterization methods to systematically understand the form of intermolecular interaction in multicomponent solution system. This review systematically discusses the determination of intermolecular interactions in diamine-diol multicomponent solutions by three mainstream research methods, theoretical calculation method, spectral method, and thermodynamic method, aiming to provide a theoretical reference for the industrial production, the supplement to experimental data, and construction and understanding of theoretical models of multicomponent solution system.

Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is...
Stability of Conjugated Dienes
A comparison of the enthalpies of hydrogenation of dienes reveals that conjugated dienes release less heat on hydrogenation, rendering them more stable than their nonconjugated analogs.
