Solvent effects on the amidic bond. 1H nuclear magnetic resonance study of acetamide and N-methylacetamide
(1981)
The influence of various common basic solvents on the 1H n.m.r. spectra of the N-H protons in N-methylacetamide and acetamide has been studied. The chemical shifts at infinite dilution show approximately linear relationships ...
Solvent-dependent inversion of circular dichroism signal in naproxen: An unusual effect!
(Wiley-Blackwell, 2018-09-01)
The electronic circular dichroism (ECD) spectra of naproxen enantiomers were studied as a function of solvents using experimental (circular dichroism) and theoretical (time-dependent density functional theory) approaches. ...
Solvation simplified
(Sociedade Brasileira de Química, 2010)
The effects of solvents on chemical phenomena is complex because there are various solute-solvent interaction mechanisms. Solvatochromism refers to the effects of solvents on the spectra of probes. The study of this ...
Electrochemical behaviour of anthraquinone dyes in non aqueous solvent solution. Part I. Medium effect on the electrochemical behaviour
(Pergamon-Elsevier Science Ltd, 2017-08)
The conditions under which alizarin, purpurin, carminc acid, quinalizarin and alizarin red S in the solution ofseveral organic solvents can be electrochemically transformed are analysed. The electrochemical activity ofthese ...
Effect of spray-drying with organic solvents on the encapsulation, release and stability of fish oil
(2018)
Fish-oil (FO) was encapsulated with hydroxypropylcelullose (HPC) by conventional spray-drying with water (FO-water) and solvent spray-drying with ethanol (FO-EtOH), methanol (FO-MeOH) and acetone (FO-Acet) in order to study ...
Quantum mechanical and molecular dynamic approaches to describe solvation effects by neoteric solvents
(Elsevier, 2020)
This review deals with the problem of designing safer solvents for chemical transformation and chemical processes. These materials generically defined as neoteric solvents include the well known ionic liquids (ILs) and ...
Influence of solvents on the electronic structure of the fluorescent probes Prodan and Laurdan.
(Instituto de Física da Universidade de São Paulo.São Paulo, 2014-05-21)
Several experimental and theoretical approaches can be used
for a comprehensive understanding of solvent effects on the electronic structure of solutes. In this review, we revisit the influence of solvents on the
electronic ...
Mechanistic pathways of aromatic nucleophilic substitution in conventional solvents and ionic liquids
(Royal Society of Chemistry, 2014)
Solvation effects on the reaction mechanism of the title reactions have been kinetically evaluated in 21 conventional solvents and 17 ionic liquids. Solvent polarity affects the catalyzed and non-catalyzed SNAr pathways ...
