Dimethylbenzylamine






Dimethylbenzylamine is the organic compound with the formula C6H5CH2N(CH3)2. 
Dimethylbenzylamine consists of a benzyl group, C6H5CH2, attached to a dimethylamino functional group. 
Dimethylbenzylamine is a colorless liquid. 
Dimethylbenzylamine is used as a catalyst for the formation of polyurethane foams and epoxy resins.

N,N-Dimethylbenzylamine can be synthesized by the Eschweiler–Clarke reaction of benzylamine

Benzyldimethylamine appears as a colorless to light yellow liquid with an aromatic odor. Slightly less dense than water and slightly soluble in water. Corrosive to skin, eyes and mucous membranes. Slightly toxic by ingestion, skin absorption and inhalation. Used in the manufacture of adhesives and other chemicals.

Dimethylbenzylamine belongs to the class of organic compounds known as phenylmethylamines. Phenylmethylamines are compounds containing a phenylmethtylamine moiety, which consists of a phenyl group substituted by an methanamine.

APPLICATION AREAS OF DIMETHYLBENZYLAMINE
Dimethylbenzylamine is used as a catalyst for soft polyester-based polyurethane systems, semisolid foams, for productions of dyestuffs, pigments and optical brighteners, pre-polymerisation agents, to improve the effect of impregnation agents on cellulose fibres.

Uses: Dimethylbenzylamine is an intermediate, especially for quaternary ammonium compounds; dehydrohalogenating catalyst; corrosion inhibitor; acid neutralizer; potting compounds; adhesives; cellulose modifier.

Benzyldimethylamine [UN2619] [Corrosive]

N,n-dimethylbenzylamine, also known as N-benzyl-n,n-dimethylamine nitrate or benzyl-dimethyl-amine, is a member of the class of compounds known as phenylmethylamines. Phenylmethylamines are compounds containing a phenylmethtylamine moiety, which consists of a phenyl group substituted by an methanamine. N,n-dimethylbenzylamine is slightly soluble (in water) and a very strong basic compound (based on its pKa). N,n-dimethylbenzylamine can be found in tea, which makes n,n-dimethylbenzylamine a potential biomarker for the consumption of this food product.

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

Dimethylbenzylamine (DMBA) is used in the production of epoxy resins.


Chemical synonyms:    N,N-Dimethylbenzylamine; BDMA
Product description
Benzyldimethylamine (BDMA) is a clear, light yellow liquid with an amine-like odor.



Applications
N,N-Dimethylbenzylamine is used in the preparation of bis[(N,N-dimethylamino)benzyl] selenide. It acts as a catalyst in the curing reaction of formulations of diglycidyl ether of bisphenol A and tetrahydrophthalic anhydride. It undergoes directed ortho metalation with butyl lithium. It reacts with methyl iodide to get ammonium salt, which is used as phase transfer catalysts. Further, it is used as a catalyst for the formation of polyurethane foams and epoxy resins.

Notes
Air sensitive. Incompatible with strong acids, strong bases, strong oxidizing agents, strong reducing agents and carbon dioxide.


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).
