Estudio de seis disolventes eutécticos de punto profundo en el proceso de extracción de hidrocarburos aromáticos de gasolinas de reformado y pirólisis. In this work, we have studied for the first time the application of DES in the extraction of aromatic hydrocarbons from reformer and pyrolysis gasolines. We have tested six choline chloride-based DES formed by ethylene glycol, glycerol, levulinic acid, phenylacetic acid, malonic acid, and urea as hydrogen bond donors.
