| Abstract: | Positive ion imidazoline surfactants were prepared.Palmitic acid and diethylenetriamine reacted under reduced pressure to form 2 alkyl 1 amidoethyl imidazoline,a ring compound.Then dimethyl sulfate was added dropwise into the imidazolines and the quaternization product positive ion imidazoline surfactant was obtained.Reaction temperature and pressure and operation time were studied too.The yield was 85% and purity of the product was about 93%. |
