Solvent Control of Electron Transfer Dynamics [PDF]

open access: yes, 2002
We investigate the charge-transfer-to-solvent (CTTS) dynamics of sodide in several solvents. Since this CTTS system has only electronic degrees of freedom, the dynamics provide a window into how solvent motions control electron ...

Solvent Effects on Electrophilicity

open access: yesJournal of the American Chemical Society, 2001
Continuum solvent effect on the electrophilicity index recently proposed by Parr and co-workers (Parr, R. G.; von Szentpaly, L.; Liu, S. J. Am. Chem. Soc. 1999, 121, 1922) is discussed in detail. Solvent effect is introduced using the self-consistent isodensity polarized continuum model (SCI-PCM).

Recycling of solvent used in a solvent extraction of petroleum hydrocarbons contaminated soil. [PDF]

open access: yes, 2011
The application of water washing technology for recycling an organic composite solvent consisting of hexane and pentane (4:1; TU-A solvent) was investigated for extracting total petroleum hydrocarbons (TPH) from contaminated soil. The effects of water

Optimisation of solvent replacement procedures according to economic and environmental criteria in pharmaceutical industry [PDF]

open access: yes, 2006
During pharmaceutical syntheses, the reaction solvent has often to be switched off from one reaction step to the following one. Because of the standard industrial practices, solvent replacement generally constitutes a slow and high solvent-consuming ...

Influence of solvent choice on the optimisation of a reaction–separation operation : application to a Beckmann rearrangement reaction [PDF]

open access: yes, 2004
In pharmaceutical syntheses, the solvent choice generally represents a complex design step. Traditionally, this choice is operated according to criteria connected with the reaction step and without any consideration on the following separation steps. The

Solvent Effects on the Menshutkin Reaction

open access: yesThe Journal of Physical Chemistry B, 2022
The Menshutkin reaction is a methyl transfer reaction relevant in fields ranging from biochemistry to chemical synthesis. In the present work, energetics and solvent distributions for NH$_{3}$+MeCl and Pyr+MeBr reactions were investigated in the gas-phase, in water, methanol, acetonitrile, benzene, and in cyclohexane by means of reactive molecular ...

Solvent effects on the photooxidation of indolepyrazines

open access: yesPhotochemical & Photobiological Sciences, 2022
AbstractPhotodestruction of 2-(pyrazin-2′-yl)-1H-indole and 2,5-di(1H-indol-2′-yl)pyrazine involves singlet oxygen generation and its rapid insertion into the indole ring with the formation of benzoxazinone derivatives: 2-(pyrazin-2-yl)-4H-3,1-benzoxazin-4-one and 2-[5-(1H-indol-2-yl)pyrazin-2-yl]-4H-3,1-benzoxazin-4-one.
