| N-hexadecyl ethylenediamine triacetate Synthesis and Properties of Sodium
Bubble volume. Experiments show that, N and sixteen, lower alkyl ED3A3Na foam, lower than the sodium lauryl sulfate,belstaff italia, sodium dodecyl benzene sulfonate, AES, and cetyl trimethyl ammonium chloride, but higher than peregal a O. Reference to the literature [4,5], adding people in the 1Ocm3 5.0cm3 cylinder 0.5% mass fraction of surfactant solution and 5.0cm3 liquid paraffin or dibutyl phthalate,ugg italia, flip up and down 100 times, fully emulsified After standing, once every 10min record volume of water phase,uggs bestellen, the same data before and after the two-phase stability of the water volume of the water separation rate: watershed stability of aqueous phase volume ratio = / 5. Diversion rate is smaller, the greater emulsifying power. The results show that, N and sixteen alkyl ED3A3Na emulsifying power of liquid paraffin is relatively good, dibutyl phthalate relatively poor emulsifying power. 3 Conclusion N-hexadecyl ethylenediamine triacetate sodium performance study shows that the stability in hard water level 4 is better than sodium lauryl sulfate and sodium dodecyl benzene sulfonate; cme 2 .13 mmol-dm ~, y for the 34.7mN �� m ~; wetting force and peregal an O,tiffany schmuck, cetyl trimethyl ammonium chloride is basically the same; dispersion force and sodium lauryl sulfate, sodium dodecyl Sodium,Ed Hardy outlet, AKS, peregal a similar O; of liquid paraffin emulsion strength is better, dibutyl phthalate poor emulsifying power; foaming power is low. |
