The LFER correlations for SN2 reactions of phenacyl bromide
, 1996 979-982The second order rate constants for the reaction of phenacyl bromide with a number of nucleophiles, viz., CO, HCO, OH-, CH3COO-, N3-, SO, phenoxide, imidazole, pyridine, aniline and thiourea have been measured in 60% acetone - 40% water(v/v ...

Model Analysis of Cellobiose Solubility in Organic Solvents and Water
, 2020 The solubility of cellobiose in 18 organic liquids and water was measured at 20°C. Hydrogen bond acceptors were the most effective solvents. Three models were analyzed to evaluate their accuracy and to understand factors that affect cellobiose solubility:

Salting-Out Effect in Aqueous NaCl Solutions: Trends with Size and Polarity of Solute Molecules
, 2016 Salting-out in aqueous NaCl solutions is relevant for the environmental behavior of organic contaminants. In this study, Setschenow (or salting-out) coefficients (Ks [M–1]) for 43 diverse neutral compounds in NaCl solutions were measured using a shared ...

Linear free energy relationship analysis of the solubility of solids in supercritical CO2
Linear free energy relationship (LFER) methods were used to construct a model for the solubility of a species in supercritical CO2. The final model was based on 64 molecules and 782 data points, employing a modified version of the Abraham LFER equation ...

Spectral LFER studies in some N-(substituted phenyl) formamides
, 2015 A series of N-(substituted phenyl) formamides were synthesised by sulphated titania (TiO2-SO4 2-) catalyzed formylation of substituted anilines and formic acid in acetonitrile medium at room temperature.

Proton shuttle mechanism in the transition state of lipase catalyzed N-acylation of amino alcohols
, 2013 International audienceAn increased reaction rate for lipase catalyzed N-acylation of amino alcohols compared to monofunctionalized amines can be explained by a hydrogen shuffling mechanism that avoids nitrogen inversion in the transition state.
