Inhalation may be fatal as a result of spasm, inflammation and edema of the larynx and bronchi, chemical pneumonitis, and pulmonary edema. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomitting.
N,N-Dimethylbenzylamine neutralizes acids on exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. May attack some plastics [USCG, 1999].
A colorless to light yellow liquid with an aromatic odor. Slightly less dense than water and slightly soluble in water. Flash point approximately 140°F. Corrosive to skin, eyes and mucous membranes. Slightly toxic by ingestion, skin absorption and inhalation. Used in the manufacture of adhesives and other chemicals.
Air & Water Reactions
Flammable. Slightly soluble in water.

Dry the amine over KOH pellets and fractionate it over Zn dust in a CO2—free atmosphere. It has a pKa2 5 of 8.25 in 45% aqueous EtOH. Store it under N2 or in a vacuum. The picrate has m 94-95o, and the picrolonate has m 151o (from EtOH). [Skita & Keil Chem Ber 63 34 1930, Coleman J Am Chem Soc 55 3001 1933, Devereux et al. J Chem Soc 2845 1957.] The tetraphenyl borate salt has m 182-185o. [Crane Anal Chem 28 1794 1956, Beilstein 12 IV 2161.]
