The Toluene Solvent Molecule

Solvant apolaire — Wikipdia

Un solvant apolaire est un solvant dont le moment dipolaire rsultant est nul Il peut donc s'agir d'une molcule ne comportant aucun groupement polaire (exemple : cyclohexane) ou d'une molcule comportant des groupements polaires mais dont la gomtrie fait que le moment dipolaire s'annule comme dans le cas du ttrachlorure de carbone

Solvent

A solvent (from the Latin solvō loosen untie solve) is a substance that dissolves a solute resulting in a solution A solvent is usually a liquid but can also be a solid a gas or a supercritical fluid The quantity of solute that can dissolve in a specific volume of solvent varies with temperature Common uses for organic solvents are in dry cleaning (e g tetrachloroethylene) as paint

Reversible absorption of toluene by switchable

Molecular dynamics simulations were performed to investigate the absorption and desorption process of toluene by two switchable hydrophilic solvents (SHSs) named N N-dimethylcyclohexylamine (CyNMe 2) and N N-dimethylaniline (DMA) Both CyNMe 2 and DMA can absorb toluene as absorption liquid solvent forming a homogeneous mixed oil phase The mixture was immiscible with water while when
