(401g) Extraction of Phenolics from Coal By Deep Eutectic Solvents
Â DESâs have already been used to extract phenolic compounds from olive oil .One potential use of this particular DES is the solvation of phenolic substances from coal. Several different DESâs were examined and tested qualitatively to see if they were able to extract phenolic compounds from coal. GCMS was used to identify extracted species. It was found that of the examined compounds ethanolamine hydrochloride and ethylenediamine showed the most promise. Various ratios of ethanolamine hydrochloride and ethylenediamine where then used to extract phenolic chemicals from Clarion 4a coal dust that had particle sizes of 35-75 micron. GCMS grade hexane was then used to extract the compounds of interest from the DES to identify. Qualitative GCMS was performed to evaluate species extracted, and quantitative mass balances were used to determine the effect of DES ratios.
