DEMULSIFICATION OF THE DENDRIMERS POLYAMIDOAMINE FOR THE SIMULATED CRUDE O/W EMULSION

Wang Jun

Open publisher page 0 citations

Abstract

A series of 1.0～3.0 G polyamidoamine (PAMAM) were synthesized with divergent method under suitable conditions with ethylenediamine as core and methanol as solvent reacting alternatively with methyl acrylate and ethylenediamine. The structure of PAMAM were characterized by IR and terminal analysis and the demulsification of PAMAM has been investigated by using the simulated O/W emulsion. The results showed that the oil phase could be separated rapidly from the emulsion and it was different from the conventional demulsifier. All the 1.0～3.0 G PAMAM can produce some effect on the emulsion. When the temperature was 50 ℃ and the 3.0 G PAMAM concentration was 100 mg/l, the dehydration rate of the simulated 5% O/W emulsion has reached 92%.
