용도
용도
N,N-Dimethylbenzylamine was used in the synthesis of bis[(N,N-dimethylamino)benzyl] selenide. It has been used as catalyst during 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.
일반 설명
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; dehydrohalogenating catalyst; corrosion inhibitor; acid neutralizer; potting compounds; cellulose modifier and quaternary ammonium compounds.
제조 및 합성 방법
제조 방법
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. 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).
