16011-97-5, N1,N4-Dimethylbutane-1,4-diamine is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
(1) Weigh 58g of hydroxyethyl acrylate in the three-necked flask, was added 50mL of methylene chloride, 90.9 g of triethylamine was added, the ice bath until the temperature drops 0 C, and after stabilization, dropwise addition of 62.7g of methacryloyl chloride, dropping control, completion of the dropwise within 120min, after completion of the dropwise addition, reaction was continued under ice-bath 3h, warmed to room temperature, the reaction was continued 24h; after completion of the reaction, stirring was stopped, the resulting solid salt was removed by filtration, and the filtrate was added to a separatory funnel, washed with deionized water 2-3 times, adding an appropriate amount of anhydrous sodium sulfate 24h, filtered, and the solvent methylene chloride was removed by rotary evaporation; (2) the reaction product weighed step (1) of 92 g, the ice bath was added dropwise N,N’-dimethyl-1,4-butanediamine 58g, addition was complete within 25min, warmed to 60 C, after the reaction 4h, 47.5g of methyl bromide was added dropwise to the reaction system, the reaction was continued 3H; (3) cooling to 40 C, deionized water was added to the reaction system to prepare a 40wt% aqueous solution.
16011-97-5, As the paragraph descriping shows that 16011-97-5 is playing an increasingly important role.
