“…Solubility in organic solvents has been shown to be dependent on the solvent’s polarity and hydrogen bonding capacity. Intermediate polarity solvents are more efficient in dissolving lignin compared to polar and non-polar solvents . In this regard, heating generally improves solubility of phenolic compounds unless the high temperature causes degradation of the molecular structure …”

“…Intermediate polarity solvents are more efficient in dissolving lignin compared to polar and non-polar solvents. 20 In this regard, heating generally improves solubility of phenolic compounds unless the high temperature causes degradation of the molecular structure. 34 Formic acid and ethanol treatments in lignin fractionation were compared to a simple alkaline isolation procedure using mild NaOH.…”

“…However, the solubility of lignin mainly depends on the types of anions present in ionic liquids. For example, anions such as [PF 4 ]and [BF 6 ]negatively affect the solubilization of lignin [56,57].…”

“…The univalent copper salt (Cu­(I)) can be stable in both aqueous and nonaqueous solutions. Since the aqueous solution of complexing extractant is highly corrosive to carbon steel and stainless steel, CuCl was selected as complexing extractant in this work, which is soluble in ethanolamine and stable in nonaqueous solution. , The method of complex extractive distillation using reversible chemical reaction to separate a mixture has not been reported in the literature before. This work applies this method to facilitate the separation of butane and butene.…”
