Fast chemical exchange will usually occur when two hydroxylic species are
present, like in solutions of ethanol- water or acetic acid- water. In such solutions,
only one PMR signal is observed for hydroxylic protons of both the species
present ...

This enabled the "masking" of the hydroxyls and the observation of the
transformation of non-hydroxylic proton selectively. Figure 2.21 illustrates
changes in the amount of mobile hydroxylic and nonhydroxylic protons as a
function of the ...

“The non-hydroxylic solvent of the preparation process is preferably acetonitrile,
toluene, or mixtures thereof. More preferably, the nonhydroxylic solvent is a
mixture of toluene and acetonitrile. “In another aspect, the present invention
relates to ...

“We have unexpectedly found that a non-hydroxylic solvent such as, for example,
DMSO, has a number of advantages over hydroxylic solvents such as methanol
and ethanol, for example, a higher solubility of atorvastatin calcium in the ...

different. For instance, the atomic polarization energy of the hydroxylic oxygen
atom in acetic acid is substantially different from that of the same oxygen in
methanol: cf. Gp(O) = +0.90 kcal/mol for acetic acid in water and Gp(O) = -2.69
kcal/mol ...

For example, the spectrum of neat ethanol usually shows the hydroxylic proton as
a slightly broadened peak at 8 5.35. At the commonly used concentration of
about 5-20% in a nonpolar solvent, such as CCI4 or CDC13, the hydroxylic peak
is ...

Aliphatic Nucleophilic Substitution
Catalysis by hydroxylic molecules in aprotic solvents. It was mentioned in an
earlier section (§1.2.3) that the reaction between tri- phenylmethyl chloride and
methanol in benzene was of no fixed order in the concentration of methanol, but
that it ...
