The distribution coefficient P ≡ Fo/Fw of pyridine between cyclohexane and water decreases when the formal concentration Fw in the aqueous phase increases. This can be explained by the self-association of the pyridine molecules in water. The data are consistent with a Mecke-Kempter model of ...
Pyridine will dissolve in water because of the strong hydrogen bonds (or dipole-dipole intermolecular interactions) that exist between the lone pair of electrons
All membranes were selective to water, but the transport mode and selectivity properties of membranes were dependent on both the character of the ion-exchange group and the ionic form of the membrane. The results obtained suggest that pervaporation of waterpyridine mixtures could be used with ...
A flammable, colorless or yellowish liquid base, C5H5N, having a penetrating odor and serving as the parent compound of many biologically important derivatives. It is used as a solvent and in the manufacture of various agricultural chemicals, rubber products, water repellents, dyes, and drugs. ...

A pyridine-free Karl-Fischer reagent for the determination of water which comprises (a) a solvent solution containing sulfur dioxide and an amine in a Karl-Fischer reagent solvent, the amine being functionally equivalent to pyridine in a Karl-Fischer reagent, and (b) a titrating agent containing...
The meaning of PYRIDINE is a toxic water-soluble flammable liquid base C5H5N of pungent odor that is the parent of many naturally occurring organic compounds and is used as a solvent and as a denaturant for alcohol and in the manufacture of pharmaceutica
