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

Ionic-interaction of aqueous and alcoholic poly(vinyl alcohol) in the presence of protons [PDF]
Journal of the Serbian Chemical Society, 2019 The ionic-interactions of acetic acid in H2O-PVOH and H2O-Alcohol-PVOH solvent systems were studied at different temperatures by viscosity method. The viscosities of the poly(vinyl alcohol) were increased with the increase in the concentration ...

Individual tuning of solvent parameters – from organic solvents to ionic liquids
Journal of Molecular Liquids, 2021 Abstract For more than 20 years, we have investigated electron transfer reactions of various types and under various conditions. According to the Marcus theory, solvent parameters have a significant influence on the observed kinetics. Temperature-dependent measurements, such as those used to obtain activation parameters, are especially strongly ...

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

Molecular basis for solvent dependent morphologies observed on electrosprayed surfaces [PDF]
, 2013 We study the causes of the observed tunable hydrophobicity of poly(styrene-co-perfluoroalkyl ethylacrylate) electrosprayed in THF, DMF, and THF/DMF (1:1) solvents. Under the assumption that equilibrium morphologies in the solvent significantly affect the

Influence of the Process Parameters on Manufactured Prepregs by Solvent Impregnation
, 2021 The properties of prepregs are characterized in terms of their volatile content, resin content, the degree of pre cure, void content, tack and flow ability. The most important properties of prepregs are resin content and volatile content.

Parameter Choice Matters: Validating Probe Parameters for Use in Mixed-Solvent Simulations [PDF]
Journal of Chemical Information and Modeling, 2014 Probe mapping is a common approach for identifying potential binding sites in structure-based drug design; however, it typically relies on energy minimizations of probes in the gas phase and a static protein structure. The mixed-solvent molecular dynamics (MixMD) approach was recently developed to account for full protein flexibility and solvation ...

Investigation of Parameters that Affect Resin Swelling in Green Solvents [PDF]
ChemistryOpen, 2020 AbstractThe influence of various physical and chemical factors on the swelling of polystyrene and PEG based resins in greener organic solvents has been systematically investigated. In general, chemical factors: the nature of the functionality/linker and the degree of loading were found to have a far larger influence on the swelling of the resins than ...

Liquid-Phase Exfoliation of Biochars in Green Solvents and Correlation with Solvent Parameters [PDF]
, 2020 Liquid-phase exfoliation (LPE) is a process frequently used to yield small sheets of layered materials. These materials are prepared via direct or indirect sonication in an ideal solvent, and the sheets produced often present remarkable chemical and physical properties.
