N,N-Dimethylbenzylamine Chemical Properties,Uses,Production

Chemical Properties

colourless to light yellow liquid with an amine odour

Uses

Intermediate, especially for quaternary ammonium compounds; dehydrohalogenating catalyst; corrosion inhibitor; acid neutralizer; potting compounds; adhesives; cellulose modifier.

Preparation

25% Aqueous Dimethylamine, 1088 grams
Benzyl Chloride, 126.6 grams
In the apparatus of Example 1, the benzyl chloride was added dropwise over a two-hour period to the amine (molar ratio 1 to 6) at a rate sufficient to maintain the temperature below 40°C. Stirring was continued at room temperature for an additional hour to insure completion of the reaction denoted by the equation below.
Preparation of N,N-dimethylbenzylamine
Thereafter the reaction mixture was cooled in a separatory funnel while standing in a refrigerator maintained at 5° C. and separated into two layers. The upper oily layer, weighing 111.5g, was removed and steam distilled until no further oleaginous component was observed in the distillate as it came over. The crude distillate was found to contain 103.5g of N,N-dimethylbenzylamine (76.1% of theory), 3.3g of dimethylamine and no quaternary salts. The dimethylamine was distilled off below 29°C under atmospheric pressure from the N,N-dimethylbenzylamine (bp 82°C/18mmHg).

General Description

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.

Reactivity Profile

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].

Health Hazard

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.

Fire Hazard

Special Hazards of Combustion Products: Toxic vapors are generated when heated.

Safety Profile

Poison by ingestion. Moderately toxic by inhalation and skin contact. Corrosive. A severe eye and skin irritant. Flammable when exposed to heat or flame. When heated to decomposition it emits toxic fumes of NOx

Purification Methods

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.]
