Study on the Performance of a New Type of Anionic-nonionic Surfactant

A series of new anionic-nonionic surfactants, biophenol polyoxyethylene ether carboxylate (BPPC), were synthesized using biophenol as raw material. The chemical structure of anionic-nonionic surfactant was determined by Fourier transform infrared spectroscopy and elemental analysis. The effects of concentration and degree of polymerization on surface tension were investigated. These new surfactants have good surface activity. The critical micelle concentration (cmc) is 9.30 x 10(-3) mol / L, 8.50 x 10(-3) mol / L, 8.10 x 10(-3) mol / L, and 7.71 x 10(-3) mol / L. The corresponding surface tensions at CMC are 28.38. mN / m, 28.60 mN / m, 30.40 mN / m, and 30.00 mN / m. Then focus on the foaming properties of BPPC. The results showed that the concentration of surfactant and Ca2+ / Mg2+ had certain effects on the foaming properties and foam stability of cashew nut-based surfactants. Due to the relatively good foam properties of BPPC, it has broad application prospects in detergents and petroleum recovery.
