Because the R-substitution stabilizes its ionization, the phenolate
is more stable, thus more favored, and its equilibrium pH shifts from 9.
Careful examination of the packing diagram reveals that one hydrogen atom is shared between two phenolate
oceanica fibres is a chemisorption process involving valency forces through sharing or exchange of electrons between phenolate
anions and sorbent biopolymers.
as copper axial ligand in structure 5 has the same effect as nitrite on copper and nitrogen spin densities, while for protonated phenol as ligand (in structure 6), the differences are much smaller (Table-4).
Upon deprotonation, the negative charge is probably localized either on the carboxylic acid group (as a carboxylate anion) or on the phenolic group (to form a phenolate
A study of the interaction of copper ethanolamine and wood components using Fourier transform infrared spectroscopy (FTIR) confirmed that Cu-EA interacts with carboxylic groups, phenolic hydroxyl groups and ester groups on lignin to form copper carboxylate and phenolate
complexes (Zhang and Kamdem 2000).
Cyasorb uv light stabilizers include UV-9, UV-24, UV-531 and UV-2126 benzophenone absorbers; UV-2337, UV-5411, and UV-5365 benzotriazole absorbers; UV2908 hindered benzoate stabilizer and UV1084 nickel phenolate
These charge transfer transitions are actually arising from the transition of pp electrons residing the phenolate
ion to dp metal orbitals.
p- Nitrophenol obtained as the result of hydrolysis of substrate was converted into phenolate
ions (yellow color) at an alkaline pH.
The early studies investigated phenolate
mediated iron transport; some experimental issues obscure the significance of the results.
