General Description
|
A clear colorless liquid with an aromatic odor. Density 0.937 g / cm3 (Lancaster) and insoluble in water. Hence floats on water. Toxic by skin absorption and inhalation. Flash point 181°F. May release toxic vapors when burned.

|
Reactivity Profile
|
N,N-DIMETHYL-P-TOLUIDINE neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides.

Purification Methods
|
Reflux for 3hours with 2 molar equivalents of Ac2O, then fractionally distil it under reduced pressure. Alternatively, dry it over BaO, distil and store it over KOH. The picrate has m 128o (from EtOH). Methods described for N,N-dimethylaniline are applicable here. [Beilstein 12 H 902, 12 III 2026, 12 IV 1874.]
