CAS Registry Number: 1300-73-8
CAS Name: ar,ar-Dimethylbenzenamine
Additional Names: dimethylaniline; aminodimethylbenzene
Molecular Formula: C8H11N
Molecular Weight: 121.18
Percent Composition: C 79.29%, H 9.15%, N 11.56%
Line Formula: (CH3)2C6H3NH2
Literature References: There are six isomeric xylidines. Prepd by reduction of corresponding nitro-compounds: Allchin, US 1867962 (to I.C.I.); physical properties of all six isomers also given: Birch et al., J. Am. Chem. Soc. 71, 1362 (1949); van Loon et al., Rec. Trav. Chim. 79, 977 (1960); Bergmann, Berkovic, J. Org. Chem. 26, 919 (1961).
Properties: All except o-4-xylidine are liquids above 20°. d 0.97-0.99, and bp 213-226°. They are sparingly sol in water, sol in alcohol and form more or less sol salts with the strong mineral acids.
Boiling point: bp 213-226°
Density: d 0.97-0.99
CAUTION: Potential symptoms of overexposure are anoxia, cyanosis, methemoglobinemia; lung, liver and kidney damage. See NIOSH Pocket Guide to Chemical Hazards (DHHS/NIOSH 97-140, 1997) p 336.
Use: Chiefly in the manuf of dyes. |
