Polar aprotic solvent

A polar aprotic solvent is a solvent that lacks an acidic proton and is polar. Such solvents lack hydroxyl and amine groups. In contrast to protic solvents, these solvents do not serve as proton donors in hydrogen bonding, although they can be proton acceptors. Many solvents, including chlorocarbons and hydrocarbons, are classifiable as aprotic, but polar aprotic solvents are of particular interest for their ability to dissolve salts. Methods for purification of common solvents are available.

Using acetal functionalization for the design of safer chemicals.

Compelling evidence shows the toxicity of several bulk chemicals encountered in daily life, including bisphenol A (BPA) and N,N-dimethylformamide (DMF). As regulations tighten, these substances are often replaced with closely related "regrettable alternatives", underscoring the need for truly safer options. In parallel, valorization of lignocellulosic biomass offers a path toward a more circular chemical industry. In this context, aldehyde-assisted fractionation (AAF) has emerged as a promising biomass fra

Life-cycle analysis of functionalized lignocellulosic sugars as biobased substitutes for polymers and solvents

A new strategy relying on aldehydes to stabilize reactive intermediates during the fractionation of lignocellulosic biomass has recently been developed. In addition to producing a highly digestible cellulose pulp and an uncondensed acetal-stabilized lignin which can be efficiently depolymerized, Aldehyde-Assisted Fractionation yields acetal-stabilized xyloses with interesting properties for the chemical industry. To determine the ability of new bio-based products to be sustainable substitutes to existing pe

Dimethyl sulfoxide

Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH3)2SO. This colorless liquid is the sulfoxide most widely used commercially. It is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water. It has a relatively high boiling point. DMSO has the unusual property that many individuals perceive a garlic-like taste in the mouth after DMSO makes contact with their skin.
