Embodiment 1
[0033] (a) Synthesis of N, N-dilauroyl ethylenediamine dimethyl propionic acid
[0034] 300 grams (1.5 moles) of lauric acid, 267.8 grams (2.25 moles) of thionyl chloride and 4.5 grams of DMF were added to a 1000-milliliter four-necked flask equipped with a sealed mechanical stirrer, a thermometer, a condenser tube, etc., and reacted at 90 ° C for 3 After one hour, excess thionyl chloride was distilled off under reduced pressure to obtain lauroyl chloride. Add 45.0 grams (0.75 moles) of anhydrous ethylenediamine and 180 grams of 1,4-dioxane to another 2000 ml four-neck flask equipped with a sealed mechanical stirrer, a thermometer, and a condenser tube, heat up to 50° C., and slowly Add 165.0 grams (1.65 moles) of methyl methacrylate dropwise, continue the reaction for 3 hours after dropping, remove unreacted methyl methacrylate and solvent 1,4-dioxane under reduced pressure, and the residue is ethylenediamine dioxane. Methyl methpropionate. Use 50wt% sodium hydroxide to adj...
