Efficient separation of phenol from oil by acid–base complexing adsorption

A N-doped porous carbon derived from deep eutectic solvent for adsorption of organic contaminants from aqueous or oil solution

“…Parameters Q e and K were denoted as adsorbance at equilibrium and the adsorption rate constant, respectively. [13][14][15] The equilibrium concentration of 4-NP and MB, C e (mg L À1 ), was determined and the equilibrium capacity, Q e (mg g À1 ), was calculated by the following:…”

Efficient extraction and theoretical insights for separating o‐, m‐, and p‐cresol from model coal tar by an ionic liquid [Emim][DCA]

“…In our previous work, [23] the mechanism and effect of 1-ethyl-3-methylimidazolium thiocyanate ([Emim][SCN]) for separating p-cresol were investigated. Gao et al [24] proved that phenol can interact with Lewis bases both theoretically and experimentally. Sidek et al [25] synthesized three benzyl imidazolium-based ILs for the separation of phenols from hexane as the model oil.…”

An ecofriendly and reusable solid acid catalyst ZrO2‐SIEC for highly selective alkylation of 2,4/2,5‐xylenol

“…As a by‐product for producing coke and coal gas from coal, low‐medium temperature coal tar is mainly composed of polyalkyl aromatics, aliphatic chain alkanes, olefins and phenols, 1,2 in which the content of phenols is as high as 20%–30%, where xylenol (in the form of a mixture of isomers) accounts for about 13%–15% of the total phenols 3–5 . Single components of 2,4‐xylenol and 2,5‐xylenol are important raw materials for the synthesis of fungicides, antioxidants and preservatives, often in high demand 6 . However, due to the very close boiling points (b.p.)…”
