Synthesis and Characterization of a Novel Cationic Type Asphalt Emulsifier

Abstract:

A novel cationic type asphalt emulsifier of 2-triethylenetetramine methylene-4-nonylphenol was synthesized by the reaction of nonyl phenol, triethylenetetramine and formaldehyde. The optimum reaction condition was obtained. The yield reaches 49.21% at the optimum reaction condition of the feedstock mole ratio of formaldehyde to nonyl phenol 2.8, feedstock mole ratio of triethylenetetramine to nonyl phenol 1.0, reaction temperature 95°C, and reaction time 5 h. The structure of the emulsifier was identified by FTIR. The emulsifier exhibits satisfactory emulsification. The emulsifier belongs to the class of rapid-set asphalt emulsifiers.
