Introduction	N,N,N’,N’-tetramethylethylenediamine is a colorless transparent liquid, slightly ammonia odor, miscible with water, miscible in most organic solvents such as ethanol, is an important organic intermediate, mainly used as biochemical reagents, epoxy resin crosslinking agent, quaternary amine compounds synthesis intermediates.
preparation	A preparation method of N,N,N’,N’-tetramethylethylenediamine catalyst for Direct Catalytic Amination of dimethylethanolamine: including the following steps:(1) weigh about 24.2g of Cu(NO3)2.3H2O, 14.5g Ni(NO3)2.6H2O and 37.5gAl(NO3)3.9H2O are dissolved in deionized water;(2) 18.0g NaOH which can completely precipitate metal ions is weighed as a precipitant, and dissolved with deionized water to a concentration of 2mol/L;(3) in the state of stirring and water bath temperature of 80 ℃, the nitrate solution prepared in step 1) is slowly added dropwise to step 2) in the prepared NaOH solution, until the pH was 8.0;(4) stirring was carried out at this temperature for 4 hours, and then allowed to stand for aging at the above temperature for 12 hours. (5) the aged catalyst is filtered with suction and washed several times with deionized water until the filtrate has a pH of 7.0; The filter cake is then dried for 32 hours; The dried catalyst is ground to a powder, then calcined in muffle furnace at 450 ℃ for 4 hours, prepared catalyst precursor, wherein the weight percentage content of Cu is 28, the weight percentage content of Ni is 11;(6) the calcined catalyst was tabletted and cut to obtain Ni-Cu/Al2O3 (20-40 mesh) 20mL of finished catalyst; 20 ML of the Ni-Cu/Al2O3 catalyst prepared above was filled in a tubular fixed bed reactor, activated by hydrogen at 250 ℃ for 12h, and fed with dimethyl ethanolamine at reaction temperature of 200 ℃ and reaction pressure of 0.2 Mpa, dimethylethanolamine was continuously catalyzed by dimethylamine and hydrogen. The molar ratio of dimethylethanolamine to dimethylamine was 1:2, and the molar ratio of dimethylethanolamine to hydrogen was 1:20. The volumetric space velocity of dimethylethanolamine was 0.5 h-1, the reaction product was continuously discharged from the lower outlet of the reactor, and the liquid product was analyzed by gas chromatography through gas-liquid separation. The conversion of dimethyl ethanolamine was 87.6%, and N,N,N’,N’-tetramethyl ethyl The diamine selectivity was 78.3%.
purpose	is a polar aprotic solvent, also used for the preparation of alkenyl alkynides and other organic reagents biochemical reagents, the water treatment agent is used as a raw material of a quaternary ammonium salt intermediate. catalysts for biochemical studies, organic synthesis, cross-linked polymerization. catalysts in the production of polyurethane foams. used as Biochemical reagent, epoxy resin crosslinking agent, and quaternary amine compound intermediate used in the preparation of polyacrylamide gel. TEMED is a tertiary amine group used to catalyze the formation of free radicals by ammonium persulfate or riboflavin. Free radicals will cause the polymerization of acrylamide and N,N’-methylenebisacrylamide to form a gel matrix useful for sieving macromolecules.
