Synthesis and characterization of lower generation broom molecules

Dendritic molecules with dodecyl groups as the hyperbranchs were synthesized in methanol by Michael addition withdodecylamine and methyl acrylate as raw materials. This new-type dendritic molecules were called vividly "broom molecules" inthis 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 wasexamined. The experimental results revealed that, as a new-type of surfactants, the broom molecules terminated amino groupsshowed demulsification for the O/W simulated crude oil emulsion.
