SYNTHESIS AND EVALUATION OF ASPHALTENE DISPERSANT BASED ON MODIFICATION OF RAPESEED OIL

In the present work the novel dispersant based on transamidation of rapeseed oil with diethanolamine was prepared. Meanwhile, for the synthesis ofeffective dispersant, rapeseed oil was used as starting material. Rapeseed oil is one of the most important renewable resources raw materials, due to its lowcost, low toxicity, high content of C18 chain in backbone and widespread availability in most regions. The structures of the prepared dispersantswere confirmed by examination of their FTIR and 1HNMR spectra. The evaluation performance of the synthesized dispersant as asphaltene dispersant wasreadily obtained by UV-Visible spectroscopy method. The obtained result showed the good efficiency of synthesized dispersant for prevention of asphaltene deposition.
