2,5,8,11-Tetraoxadodecane (cas: 112-49-2) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. But ether is more polar than alkenes. Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.Category: ethers-buliding-blocks

Solvate Structures and Computational/Spectroscopic Characterization of LiClO4 Electrolytes was written by Daubert, James S.;Afroz, Taliman;Borodin, Oleg;Seo, Daniel M.;Boyle, Paul D.;Henderson, Wesley A..

A Raman spectral evaluation of numerous crystalline solvates with lithium perchlorate (LiClO4) has been conducted over a wide temperature range. Two new solvate crystal structures-(PMDETA)1:LiClO4 and (THF)1:LiClO4 with N,N,N’,N”,N”-pentamethyldiethylenetriamine and tetrahydrofuran-have been determined to aid in this study. With a help of d. functional theory (DFT) and mol. dynamics (MD) simulations, the spectroscopic data have been correlated with varying modes of ClO4–···Li+ cation coordination within the solvate structures to create a characterization tool to facilitate the Raman band assignments for the determination of ionic association interactions within solid and liquid electrolytes containing LiClO4. This study demonstrates that many of the spectroscopic evaluation conclusions reported in the scientific literature for LiClO4-based electrolytes are inaccurate. In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2Category: ethers-buliding-blocks).
