hydric's Usage Examples:

Impure inactive forms result on the polymerization of glycollic aldehyde and also on the oxidation of erythrite, a tetrahydric alcohol found in some lichens.

esters formed by the union of three molecules of fatty acids with one molecule of the trihydric alcohol glycerin, whereas the waxes consist of esters formed by the union of one molecule of fatty acid with one molecule of a monohydric alcohol, such as cetyl alcohol, cholesterol, 'c.

In order that the solutions of these should be isohydric and the concentrations of the hydrogen ions the same, we must have a very large quantity of the feebly dissociated acetic acid, and a very small quantity of the strongly dissociated hydrochloric, and in such proportions alone will equilibrium be possible.

Glycols may be classified as primary, containing twoCH(OH groups; primary-secondary, containing the grouping - CH(OH) CH (OH; secondary, with the grouping - CH(OH) CH(OH) -; and tertiary, with the grouping > C (OH) (OH) CGLYCOLS, in organic chemistry, the generic name given to the aliphatic dihydric alcohols.

Monatomic or monohydric alcohols contain only one hydroxyl group; diatomic, two, known as glycols; triatomic, three, known as glycerols; and so on.

The starting point was ordinary(d)mannite (mannitol),C 6 H 14 0 61 a naturally occurring hexahydric alcohol, which only differed from a-acritol, the alcohol obtained by reducing a-acrose, with regard to optical activity.

Such solutions were called by Arrhenius " isohydric.

GLYCOLS, in organic chemistry, the generic name given to the aliphatic dihydric alcohols.

On reduction glucose appears to yield the hexahydric alcohol d-sorbite, and on oxidation d-gluconic and d-saccharic acids.

Only in the case of the wax coccerin two molecules of fatty acids are combined with one molecule of a dihydric (bivalent) alcohol.

Our knowledge of the chemical structure of the monosaccharoses may be regarded as dating from 1880, when Zincke suspected some to be ketone alcohols, for it was known that glucose and fructose, for example, yielded penta-acetates, and on reduction gave hexahydric alcohols, which, when reduced by hydriodic acid, gave normal and secondary hexyliodide.

RESORCIN (meta-dioxybenzene), C 6 11 4 (OH) 2, one of the dihydric phenols.
