Extractability and Reactivity of OH- in Low-Polarity Media under Phase-Transfer Catalysis Conditions: Dramatic Effect of the Aqueous Base Concentration

In the chlorobenzene-aqueous NaOH two-phase system, an increase in NaOH concentration from 15percent to 50percent produces both a decrease in the extractability and an enhancement in the reactivity of OH- in the organic phase as quaternary ammonium hydroxide 1d.

BIOACTIVE PHENOLATE IONIC COMPLEXES

The invention provides an isolated material, or a phenolate form of at least one phenol- containing active material, wherein the isolated material comprises one or more phenolate species and a counter ion (a cation) in the form of a metal salt, a phosphonium or an ammonium.

Synthesis of high proton conducting nanoparticles by emulsion polymerization

High ion-exchange capacity (IEC) sulfonated polystyrene nanoparticles were synthesized by an emulsion copolymerization of styrene, divinyl benzene and sulfonated styrene (SS). The effects of varying the counterion of the sulfonated styrene monomer, the SS concentration, the surfactant and the addition of a crosslinking agent on the ability to stabilize the emulsion nanoparticles to high IEC were studied. Water-insoluble nanoparticles, 20-160 nm in diameter, with IEC as high as 5.2 meq/g were achieved using sulfonated styrene with a quaternary alkyl ammonium cation, a non-ionic surfactant and a crosslinking agent in the emulsion formulation. That IEC corresponds to fully sulfonated crosslinked polystyrene.
