Adsorption, wetting, foaming, and emulsification properties of mixtures of nonylphenol dodecyl sulfonate based on linear alpha-olefin and heavy alkyl benzene sulfonate

摘要

Nonylphenol dodecyl sulfonate (C(12)NPAS) has been synthesized, and mixed with heavy alkyl benzene sulfonates (HABS) in different proportions. The effects of different mixing ratios on properties such as adsorption, wetting, foaming, and emulsification, of the C(12)NPAS/HABS surfactant mixtures have been systematically investigated. Experimental results have shown that, after mixing, the wetting and foaming properties of C(12)NPAS/HABS are improved remarkably. Compared with C(12)NPAS and HABS alone, the adsorption and emulsifying properties of C(12)NPAS/HABS are far superior, which we attribute to a synergistic effect between these surfactants.
