- n. In chem., an amine derivative from the hydrocarbon xylene, itself obtained from coal-tar. The general formula for xylidine is C6H3(CH3)2NH2, but there are six isomeric forms, of which two form the greater part of the oily liquid industrially known under this name and used in the manufacture of artificial dyestuffs.

- n. (Chem.) 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
“Müller's first researches concerned the chemical and electrochemical oxidation of m-xylidine, and his early work at J.R. Geigy concerned vegetable dyes and natural tanning agents.”
“It is well known that in coal-tar is found a series of ammonia-like bases, aniline or amido-benzol, toluidine or amido-toluol, and xylidine or amido-xylol, which are utilized practically in the manufacture of the so-called aniline dye-colors.”
“After they burn out and drop away (between 3 to 5.1 seconds from launch) it fires a 5D67 liquid fueled sustainer rocket engine (for 51-150 seconds) which burns a fuel called TG-02 Samin (50% xylidine and 50% triethylamine), oxidized by an oxidizing agent called AK-27P Melange (fuming nitric acid enriched with nitrogen oxides, phosphoric acid and hydrofluoric acid) .”
