The solubility of water in methylene chloride and I: 2-dichloro-ethane over the temperature range - 20° to 40° and 80° respectively has been determined. The vapour pressures of the solvents, alone and in admixture, have been measured, and the composition of the varour phases of the ...
pointoftheradiusvectorrepresentsthe solubility parameter. This means that each solvent and each polymer can be located in a three-dimensioned space. The distance ) between the end-points of the vectors representing the polymer and solvent is given as where the subscripts p and s refers to polymer...
A biphasic controlled release delivery system for pharmaceuticals which have high water solubility, such as the antidiabetic metformin HCl salt, is provided which provides a dosage form that has prolonged gastric residence so that a dosing regimen of at least one gram metformin, once daily, may be...
The ET values were found to correlate closely with the solu- bility of water in those solvents, expect for 1,2-dichloroethane. The solubility of water in some of these solvents was significantly interrelated with the various equilibrium constants in the extraction of copper (II) with decanoic ...
The mechanism of an ion transfer assumes the partial replacement of the water molecules in the first hydration layer of the transferred ion by molecules of the organic solvent. Spectroscopic evidence is presented pointing to the absence of water clusters in pure 1,2-dichloroethane saturated with ...
The solubility of 1,3-dinitropyrazole in a selection of twelve solvents, including water, methanol, ethanol, acetonitrile, hexane, cyclohexane, dichloromethane, dichloroethane, benzene, toluene, ethyl acetate, and acetone, was measured by the gravimetric technique across a temperature spectrum from ...
Solubility data were determined experimentally for the following pairs of liquids: 1-butanol-water, benzene-water, methanol-hexane, pentane-water, toluene-water, 1,2-dichloroethane-water, and methylene chloride-water, employing equipment normally used to obtain liquid–liquid equilibrium data. The ...
CIP-45 also transfers from dichloroethane solution: about 100% transfers into water and less than 10% transfers into 0.01M HNO3. This compound fully transfers from p-xylene even into 0.3M HNO3 solution. Less than 5% of CIP-67 (with propyl substituents at phosphorus atom) transfer from organic...
Similarly, collection of further 60 solvents provided in Table 2 can also be classified according to the consonance rule. Although the best reference solvent for class B is nonan-1-ol but also such solvents as 1,2-dichloroethane, 1,2-dibromoethane, iodobenzene, butanoic acid or decan-1-ol...
