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.
