Aqueous solubility of chloroguaiacols

Journal of Chemical & Engineering Data, 1994
The aqueous solubilities of guaiacol (2-methoxyphenol) and seven chlorinated guaiacols are reported at 25 o C, and for five of these over a temperature range from 5 to 45 o C, from which the enthalpies of solution are deduced. It is shown that the solubilities are well corrected with molar volume and that chlorinated phenols and guaiacols follow ...

Aqueous solubility of permethylsiloxanes (silicones)

Environmental Toxicology and Chemistry, 1996
Abstract The aqueous solubility of several low mlecular weight linear, cyclic, and branched permethylsiloxanes was determined at room temperature. A method for preparing molecularly dispersed, colloid-free saturated aqueous solutions is described.

Solubility of Doxycycline in Aqueous Solution

Journal of Pharmaceutical Sciences, 1979
The solubility of doxycyline monohydrate and doxycycline hydrochloride dihydrate was investigated in aqueous solution. The hydrochloride dihydrate salt was isolated and identified from solutions initially containing doxycycline hyclate in water.

Database for aqueous solubility of nonelectrolytes

Bioinformatics, 1989
The ARIZONA dATAbASE of Aqueous Solubility was developed. At the present time, it is the largest and most comprehensive compilation of aqueous solubility available for unionised organic compounds. The solubility data, which are extracted from various scientific articles, are objectively evaluated by five criteria: temperature, solute purity ...

Entacapone: Improving Aqueous Solubility, Diffusion Permeability, and Cocrystal Stability with Theophylline

Crystal Growth & Design, 2018
Cocrystallization is a well-established technique to improve the solubility, bioavailability, and stability of active pharmaceutical ingredients (APIs) but permeability and diffusion rate control via cocrystals is relatively less well studied, and the ...

In Silico Prediction of Aqueous Solubility: The Solubility Challenge

Journal of Chemical Information and Modeling, 2009
The dissolution of a chemical into water is a process fundamental to both chemistry and biology. The persistence of a chemical within the environment and the effects of a chemical within the body are dependent primarily upon aqueous solubility. With the well-documented limitations hindering the accurate experimental determination of aqueous solubility,

Prediction of aqueous solubility of compounds based on neural network

Molecular Physics, 2019
Neural network algorithms are gradually applied to the field of chemical informatics. In this paper, the neural network models are used to predict the properties of compounds based on Molecular Information. We predict the aqueous solubility of compounds,

Solubility Determination of Barely Aqueous-Soluble Organic Solids

Journal of Pharmaceutical Sciences, 1979
Solubility determination of organic molecules having very low solubilities is hampered by such problems as slow equilibration during measurement, influence of impurities, and inherent heterogeneity in the energetic content of the crystalline solid. Three approaches to meeting these problems are presented.

Modeling the Aqueous Solubility of Aliphatic Alcohols

SAR and QSAR in Environmental Research, 1998
A comparison of several structure-properly models for predicting the solubility of aliphatic alcohols in water is presented. Models based on the valence vertex-connectivity indices are better than models based on weighted edge-connectivity indices or vertex-connectivity indices or parameters related to the molecular surface area.

Solubility of Ethylene in Aqueous Silver Nitrate

Journal of Chemical & Engineering Data, 1995
The solubility of ethylene was measured at pressures up to 0.64 MPa, at silver nitrate concentrations from 1.0 to 6.0 M, and over a temperature range from 278 to 308 K. From the temperature dependence of the solubility, values were determined for enthalpy and entropy changes.
