Dendritic molecules with dodecyl groups as the hyperbranchs were synthesized in methanol by Michael addition with dodecylamine and methyl acrylate as raw materials. This new-type dendritic molecules were called vividly "broom molecules" in this report. The surface tension of the aqueous solution of broom molecule terminated amino group was measured by using the drop-volume method. The demulsification performance of the broom molecules for the oil/water (O/W) simulated crude oil emulsion was examined. The experimental results revealed that, as a new-type of surfactants, the broom molecules terminated amino groups showed demulsification for the O/W simulated crude oil emulsion.
