Solid-Liquid Separation Properties of Thermoregulated Dicationic Ionic Liquid as Extractant of Dyes from Aqueous Solution

Dicationic Ionic Liquid as the Recyclable Catalyst for the Synthesis of Quinoxaline Derivatives

An efficient and eco-friendly protocol for the synthesis of quinoxaline derivatives employing a condensation reaction between 1,2-diketone and 1,2-diaminobenzene derivative has been developed. The reaction of  1,2-diketone and 1,2-diaminobenzene derivative was carried out in water at room temperature using 10 mol% of task-specific dicationic ionic liquid as a catalyst. The results show that...

Complete removal of textile dyes from aqueous media using ionic-liquid-based aqueous two-phase systems

Solid-liquid separation after liquid-liquid extraction.

A low-melting solid is used as organic solvent for liquid-liquid extraction at elevated temperatures followed by solidification and decantation of the aqueous phase.

Effect of spacer chain length on the liquid structure of aqueous dicationic ionic liquid solutions: molecular dynamics studies.

The liquid structure of aqueous solutions of five different imidazolium based gemini dicationic ionic liquids 1,n-bis(3-methylimidazolium-1-yl) alkane bromide (n being the length of the spacer alkyl chain), with propyl, pentyl, octyl, decyl and hexadecyl spacer chains has been studied using atomistic molecular dynamics simulations. While solutions with propyl and pentyl spacers are homogeneous,...

Magnetic removal of acid dyes from wastewater with ionic liquid linked-nanoparticles

The acid dyes are one of the most widely used commercial dyes used in the textile industries. This work investigates the ability of magnetite nanoparticles functionalized with imidazolium based ionic liquid as an efficient sorbent for removal of the Acid Blue 113 from wastewater. Fourier Transform Infrared Spectroscopy FT-IR, X-ray diffraction XRD and Transmission Electron Microscopy TEM were u...
