Anti-knock quality of sugar derived levulinic esters and cyclic ethers

, 2017
The objective of this paper is to investigate the anti-knock quality of sugar-derived levulinic esters (methyl levulinate (ML) and ethyl levulinate (EL)) and cyclic ethers (furfuryl ethyl ether (FEE) and ethyl tetrahydrofurfuryl ether (ETE)). To this end,

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

REACTIONS OF CYCLIC OXIDES UNDER BIFUNCTIONAL HETEROGENEOUS ACID-BASE CATALYSIS

Cifra: Химия
The reactions of cyclic epoxides form the basis for many industrial chemical technology processes. Unlike simple ethers, oxiranes tend to undergo nucleophilic cleavage reactions. The chemical properties of cyclic alkanes are primarily determined by their

Nickel-Catalyzed Carbonylative Synthesis of Functionalized Alkyl Iodides

iScience, 2018
Summary: Functionalized alkyl iodides are important compounds in organic chemistry and biology. In this communication, we developed an interesting nickel-catalyzed carbonylative synthesis of functionalized alkyl iodides from aryl iodides and ethers. With

Caveat in alkylative fragmentation of aldehyde tosylhydrazones of cyclic ethers

, 1998
Tosylhtdrazones of aldehydes at the α-position of cyclic ethers when exposed to carbon nucleophiles produce either ring opened alkylated olefinic alcohols and/or cyclic alkylated vinyl ethers, the ratio of which is dependent on nature of hydrazone and ...

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

Advanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries
