Valerianic; specifically, designating any one of three metameric acids, of which the typical one (called also inactive valeric acid), C4H9CO2H, is obtained from valerian root and other sources, as a corrosive, mobile, oily liquid, having a strong acid taste, and an odor of old cheese. Active valeric acid, a metameric v…

carbon, C12H19N7, obtained from coal tar, and probably consisting of a mixture of several metameric compounds which are higher derivatives of the base pyridine.

Any of a group of three metameric hydrocarbons of the aromatic series, found in coal and wood tar, and so named because found in crude wood spirit. They are colorless, oily, inflammable liquids, C6H4.(CH3)2, being dimethyl benzenes, and are called respectively orthoxylene, metaxylene, and paraxylene. Called also xylol.…

ne of two distinct acids which are derived from xylic acid and related compounds, and are metameric with uvitic acid.

Any one of six metameric hydrocarbons, (CH3)2.C6H3.NH2, resembling aniline, and related to xylene. They are liquids, or easily fusible crystalline substances, of which three are derived from metaxylene, two from orthoxylene, and one from paraxylene. They are called the amido xylenes.

Any one of three metameric radicals which are characteristic respectively of the three xylenes.
