XYLIDINE
Xy"li*dine, n. (Chem.)
Definition: 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.
Note: The xylidine of commerce, used in making certain dyes, consists
chiefly of the derivatives of paraxylene and metaxylene.
