Aqueous dimethylformamide, a solvent for aromatic hydrocarbons

One pot synthesis of environmentally friendly lignin nanoparticles with compressed liquid carbon dioxide as an antisolvent

“…86 The C/O ratios for the KL-raw and PKL-1 were 2.5 and 3.1, respectively which is probably due to the selectively extraction of aromatic hydrocarbons by DMF during the dissolving process. 87 The analysis of these spectra clearly demonstrates significant changes in the chemical state of lignin before and after the PCA process. The core level spectra of C 1s and O 1s with the fitting data for the KL-raw and PKL-1 are presented in Fig.…”

Solvent extraction of aromatic components from petroleum derived fuels: a perspective review

“…But the published literature was lacking in comparative data from studies of MMF and DMF as solvents for low molecular weight aromatic hydrocarbons. Therefore, a comparative study was made by Ledyashova and Dorogochinskii 76,77 on the results of the extraction of aromatic hydrocarbons with MMF and DMF and also with diethylene glycol (DEG) and triethylene glycol (TEG). They reported that MMF and DMF possess a high solvent power towards aromatic hydrocarbons.…”
