Abstract:

In this work, we performed all-atom molecular dynamics simulations of the ionic liquids choline chloride (ChCl) and 1-ethyl-3-methylimidazolium chloride, as well as their mixtures with ethylene glycol (ETG) and urea (UR), to obtain deep eutectic solvents (DESs). We calculated the structural and transport properties of all systems studied to explore the differences between pure ILs and DESs. From these results, we discuss the ability of ETG and UR to orient themselves along the ionic electric field, similarly to water in classical electrolytes. This orientational behavior promotes an effective reduction of the electrostatic interactions (usually called "screening" within the context of classical electrolytes). We found that, similar to inorganic salts dissolved in water, the hydrogen-bond donors reduce electrostatic interactions between ions, leading to significant changes in their structural and transport properties.

Physical Properties Affecting Solubility

Physical Properties Affecting Solubility

Solutions of Gases in Liquids
As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between solute and solvent species. Unlike solid and liquid solutes, however, there is no solute-solute intermolecular attraction to overcome when a gaseous solute dissolves in a liquid solvent since the atoms or molecules comprising a gas are far separated and experience negligible interactions. Consequently, solute-solvent interactions are the sole...

Physical Principles Governing Gas Exchange

Physical Principles Governing Gas Exchange

Gas behavior plays a vital role in understanding bodily processes such as external and internal respiration. External respiration involves the diffusion of oxygen into the blood and carbon dioxide out of it in the lungs. In contrast, internal respiration happens in body tissues, where these gases move in opposite directions.
Gas Laws Governing Respiration
The behavior of gases is guided by Dalton's Law of partial pressures and Henry's Law.
Dalton's Law asserts that the total...

Physical Properties of Amines

Physical Properties of Amines

Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.

Physical Properties of Alkanes

Physical Properties of Alkanes

Alkanes are nonpolar molecules due to the presence of only carbon and hydrogen atoms. The electronegativity difference between carbon and hydrogen is minimal, and hence alkanes have a zero dipole moment. This leads to the presence of only dispersion forces between the molecules. The strength of dispersion forces is dependent on the surface area of the molecules on which they act. Since the surface area increases with the molecular length for straight-chain alkanes, the dispersion forces also...

Physical Properties of Ethers

Physical Properties of Ethers

Overview
An ether molecule has a net dipole moment due to the polarity of C–O bonds. Subsequently, boiling points of ethers are lower than those of alcohols of comparable molecular weight and slightly higher than those of hydrocarbons of comparable molecular weight (Table 1).
Ethers can act as hydrogen bond acceptors, making them more water-soluble than hydrocarbons, but since ethers cannot act as hydrogen bond donors, they are much less soluble in water than alcohols. Ethers are considered...
