| Use | Used as a detergent, it can significantly improve washing power and bubble power, and can also be used as a wetting agent, calcium soap dispersant, and defoamer. 50kg/plastic bucket, 100kg/plastic bucket, or woven bag packaging lined with plastic bags. |
Put N, N-dimethylpropanediamine into a reactor, stir and dissolve dichloromethane, cool to 8 ℃, add p-octadecylbenzenesulfonyl chloride dropwise, stir at room temperature for 4 hours, and then neutralize hydrogen chloride with 10% sodium carbonate aqueous solution. Stir for 20 min, separate water layer, evaporate dichloromethane, and then evaporate unreacted amine under reduced pressure to obtain N, N-dimethyl-N '- p-octadecylbenzene sulfonyl group ethylenediamine. Slowly add propionyl lactone dropwise while stirring. After dripping, react at 80 ℃ for 4 hours, evaporate the solvent to obtain the crude product, and recrystallize with 70% ethanol to obtain a white solid.
It cannot be mixed with cationic compounds. It should be stored in a cool and ventilated warehouse.
