Embodiment 1
[0032] (1) Dissolve 46.45g (0.4mol) of hydroxyethyl acrylate in 50ml of methanol, and add 6.01g (0.1mol) of ethylenediamine dropwise at -10°C. After the dropwise addition, continue to stir for 2 hours, then raise the temperature to 20°C and continue to stir at a constant temperature until the infrared detection 1640 and 810cm -1 The left and right double bond absorption peaks disappeared, the reaction was stopped, and the solvent methanol was removed to obtain 49.85 g of N, N, N', N'-tetrahydroxyethylcarboxyethyl-ethane-1,2 diamine;
[0033] (2) Add 34ml of acryloyl chloride dropwise to 200ml of dichloromethane solution containing 49.85g of N,N,N',N'-tetrahydroxyethylcarboxyethyl-ethane-1,2 diamine and 80g of triethylamine In , the reaction was carried out in an ice bath at 0-5° C. After 4 hours of reaction, the stirring was stopped and left standing overnight. After standing overnight, the reaction was terminated, washed with water, 1M hydrochloric acid, and 1M NaOH solution...
Embodiment 2
[0040] (1) 58.06g (0.5mol) of hydroxyethyl acrylate was dissolved in 50ml of methanol, and 10.32g (0.1mol) of diethylenetriamine was added dropwise at 0°C. After the dropwise addition, continue to stir for 2 hours, then raise the temperature to 25°C and continue to stir at a constant temperature until the infrared detection 1640 and 810cm -1 The left and right double bond absorption peaks disappeared, the reaction was stopped, and the solvent methanol was removed to obtain 64.97g N 1 , N 1 , N2 , N 3 , N 3 - Pentahydroxyethylcarboxyethyl-diethylenetriamine;
[0041] (2) Add 43ml of acryloyl chloride dropwise to the 1 , N 1 , N 2 , N 3 , N 3 -Pentahydroxyethylcarboxyethyl-diethylenetriamine 64.97g and tripropylamine 110g in ethyl acetate 300ml solution, react in an ice bath at 0-5°C, after reacting for 4 hours, stop stirring and let stand overnight. After standing overnight, the reaction was terminated, washed with water, 1M hydrochloric acid, and 1M NaOH solution succ...
Embodiment 3
[0048] (1) 81.28g (0.7mol) of hydroxyethyl acrylate was dissolved in 50ml of methanol, and 18.93g (0.1mol) of tetraethylenepentamine was added dropwise at 10°C. After the dropwise addition, continue to stir for 2 hours, then raise the temperature to 50°C and continue to stir at a constant temperature until the infrared detection 1640 and 810cm -1 The left and right double bond absorption peaks disappeared, the reaction was stopped, and the solvent methanol was removed to obtain 95.20g N 1 , N 1 , N 2 , N 3 , N 4 , N 5 , N 5 - Heptahydroxyethylcarboxyethyl-tetraethylenepentamine;
[0049] (2) Add 60ml of acryloyl chloride dropwise to the 1 , N 1 , N 2 , N 3 , N 4 , N 5 , N 5 -Heptahydroxyethyl carboxyethyl-tetraethylenepentamine 95.20g and tri-n-butylamine 175g in n-hexane 500ml solution, react in an ice bath at 0-5°C, after reacting for 4 hours, stop stirring and let stand overnight. After standing overnight, the reaction was terminated, washed with water, 1M hy...
