Furthermore, hydrazide-hydrazone derived compounds are dissolved in polar aprotic solvents (DMSO-d6), the geometrical E isomers of these compounds undergo a rapid cis/trans amide equilibrium, in which the trans conformer predominates [14, 48-50].
The polymers are formed by oxidation polymerization of monomers such as pyrrole and thiophene from solutions with polyacid, water and an aprotic solvent such as N methylformamide.
Both the salt and acid forms of the copolymers were completely dissolved in polar aprotic solvents such as NMP, DMF.
However, membranes themselves are nearly always produced using costly, harmful and environmentally unfriendly aprotic solvents such as N-methyl-pyrrolidone (NMP), dimethylformamide (DMF), or dimethylacetamide (DMAC).
Processing is carried out in an aprotic, water-soluble solvent like methyl ethyl ketone (MEK) or n-methyl pyrrolidinone.
9,078,829 B2; Yagna Limited, London, patented a method of treating hair loss that entails applying a formulation that comprises at least one hair loss treating ingredient known to inhibit the hormonal mechanism underlying androgenetic hair loss, a C6-C14 dicarboxylic acid, and a mixture of water and at least one aprotic organic solvent, wherein the mixture of water and aprotic organic solvent is capable of solubilizing sebum and allowing at least one ingredient to reach the skin and/or hair follicle.
N-Methyl-2-Pyrrolidone, also referred to as N-Methylpyrrolidone, is an organic, colourless, polar aprotic solvent characterised by relatively lower volatility and higher flash point.
The solvent used was tetrahydrofuran, an aprotic solvent with dielectric constant (e) 7.
The class of compounds known as polar aprotic solvents, which include DMSO (yellow) and DMF (red), is particularly frustrating for green chemistry researchers as the solvents are very useful and popular, but not very green.
Meanings of terms like ferromagnetic, solvate, and aprotic also were not recognised by majority.
This claim has been demonstrated in the research of Auzely-Velty and Rinaudo (2003), for the synthesised starch betaine derivatives using disopropylcarbodiimide and 4-dimethylaminopyridine as coupling agents in an aprotic polar solvent, which carry cleavable cationic groups derived from naturally occurring glycine-betanine.
All experiments were carried out in acetonitrile as an aprotic solvent, under reflux reaction conditions.
