Abstract
In this study, a novel deep eutectic solvent (DES) triethylamine/salicylic acid was synthesized and was used for the extractive denitrogenation of model oil. The structure of the DES was analyzed by fourier transform infrared spectrometry and the factors that influence nitrogen removal efficiency were investigated. Under the conditons of 20 min time, 30 °C temperature, 800 rpm stirring speed, 1:1 mass ratio of DES to oil, nitrogen removal efficiency reached more than 95%. After two extraction stages the nitrogen content of model oil could be reduced to less than 10 ppm. Therefore, the novel DES triethylamine/salicylic acid will became a promising extractant for fuel oil denitrogenation.
