Synthesis and Surface Active Properties of Amphoteric Surfactant Derivatives(II);Surface Active Properties of N-Alkyl or Acyl Hydroxy sulfobetaines
pp.79-85
All the activities and physical properties including surface tension' foaming power, foam stability, emulsifying power, dispersion effect of 3-(N, N-dimethyl N-alkylammonio)-2-hydroxyY-1-propane sulfonate (HSB)류와 3-CN-alkylamidopropyl-N,N-dimethylamm-onjo)-2-hydroxy-1-propane sulfonate (APSB) aquous solution were measured and critical micelle concentration was evaluated. Their cmc of hydroxy sulfobetaine derivatives evaluated by the surface tension method was 1.0×10-3~1.0×10-4 mol/l, and surface tension of the aquous solution was decreased to 27~38dyne/cm. The experimental results for foaming power, foam stability, emulsifying power in liquid paraffin showed a good surface active properties, especially, dispersion effect in ferric oxide exhibited some efficient surface active properties, and then it would be expected to application as detergent and dispersion agent.
