Molar Mass | 644.0 |
Physical and Chemical Properties | Bright brown waxy solid, soluble in methanol and ethanol, insoluble in water, with infrared characteristic absorption of 1190-1180cm-1. |
Put 1.3mol of N, N-bis (2-hydroxyethyl) -1,3-propanediamine into a reactor, dissolve it in dichloromethane, cool to 8 ℃, and then start dripping a methanol solution of para octadecylbenzenesulfonyl chloride (1.05mol). After dripping, stir at 25 ℃ for 4 hours, add 10% sodium carbonate, and stir at 25 ℃ for 30 minutes. Separate the water layer for azeotropic distillation to evaporate the solvent to obtain N, N-dihydroxyethyl-N '- para octadecylbenzenesulfonylphenylenediamine. Add 1.15mol of propionolactone, stir at 25 ℃ for 4 hours, and evaporate the solvent to obtain the product.
Cannot blend with cationic compounds. It should be stored in a cool and ventilated warehouse.
