The effect of solvent on the α-effect: the MeCN–H2O solvent system

Chemical Communications, 2000
The increasing α-effect observed in MeCN–H2O solvent mixtures, which contrasts with the previously found bell-shaped dependence on solvent composition in the DMSO–H2O system, is attributed to the differential solvent effect on basicities of the α- and normal nucleophiles in the former case.

Solvent effects on the wood delignification with sustainable solvents

International Journal of Biological Macromolecules, 2022
Solutions of a pure organic solvent acidified with 1% sulfuric acid, and some of their aqueous mixtures were used for lignin extraction in the Pinus radiata sawdust delignification. Organic acid solvents including acetic, lactic and citric acids as well as non-acidic compounds such as γ-valerolactone, 2-methyltetrahydrofuran, glycerol and ethylene ...

Solvent effect in a “solvent free” reaction

CrystEngComm, 2007
Vapour digestion of a mixture of solid [Fe(η5-C5H4–C5H4N)2] and solid pimelic acid HOOC(CH2)5COOH in the presence of solvent vapours generates co-crystals of different stoichiometry depending on the protic or aprotic nature of the solvent. The nature of the products has been ascertained by a combined use of SSNMR and X-ray diffraction.

Solvents and Solvent Effects:  An Introduction

Organic Process Research & Development, 2006
Solution chemistry is carried out in solvents, that is in liquids under the conditions of application, which can exert a considerable influence on the properties of the dissolved solute species. A short historical overview on the influence of solvents on chemical processes (equilibria, reaction rates) and physical processes (absorption spectra ...

Solvent Effects on the Formation of Surface Nanodroplets by Solvent Exchange

Langmuir, 2015
Solvent exchange is a simple process to form oil nanodroplets at solid-liquid interfaces with well-defined location and morphology. In this process, a good solvent of the oil is displaced by a poor solvent, leading to the nucleation and growth of oil droplets from a transient oversaturation at the mixing front.

The effects of the solvent

2003
This chapter focuses on the effects of the solvent. It regards solvent as a crucial component of reactions while referencing the reaction of t–butyl chloride. The rate of formation of either the substitution or elimination product depends only on the rate of the initial step.
