An evaluation of mol. interactions is important for estimating macroscopic properties, such as solubility and diffusivity. In this study, for several types of ethylene glycol-based absorbents, we discuss the correlation between a macroscopic property (mol. diffusivity) and a microscopic criterion (residence time) using mol. dynamics simulations for pure solvent systems and CO2-loaded solvent systems. The neg. correlations between the diffusivity and the residence time can be divided into categories, depending on the number of constituent hydroxy groups of the solvent mols. The disparity between the categories arises from whether hydrogen bonding can be formed between the solvent mols. This study leads to the systematic estimation of the mol. diffusivity from the theor. prediction of the residence time. We believe that the residence time is suitable as a criterion to evaluate macroscopic properties. In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2Electric Literature of C8H18O4).
2,5,8,11-Tetraoxadodecane (cas: 112-49-2) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. But on the other hand, ethers undergo cleavage by reaction with acids. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides.Electric Literature of C8H18O4
