Description and Uses
There are six xylidine isomers. Xylidine,mixed isomers (principally made up of 2,4-, 2,5-, and 2,6-isomers), is a pale yellow to brown liquid with a weak,aromatic amine odor. The odor threshold is 0.056 ppm.Molecular weight=121.20; Specific gravity (H2O:1) =0.98 at 25℃; Boiling point (mixed isomers) =213-226℃;Freezing/Melting point=236℃; Vapor pressure =<1 mmHg at 25℃; Flash point (2,6-isomer)= 91℃;(mixed isomers) 96.7℃. Explosive limits (2,6-isomer):LEL =1.0%; UEL—unknown. Hazard Identification (basedon NFPA-704 M Rating System): Health 3, Flammability 1,Reactivity 0. Insoluble in water.
Chemical intermediate in the manufacture of pesticides, dyes, antioxidants, pharmaceuticals, synthetic resins, and fragrances.
