Abstract The accumulation of non‐biodegradable plastic waste in land and aquatic environments is expanding every day. According to data collected from various scientific reports, about 100–250 megatonnes arrives the oceans annually. Central Control Board India (2019–2020), produces 3.5 million metric tonnes annually, while only 5–10% produced recycled. non‐recycled dumped into environment either goes landfills or directly sea, which disrupts marine life ocean. We are highly dependent on at...

The lower alcohols tend to form azeotropic solution with water which makes the separation challenging. current work primarily focuses on synthesis and application of a menthol-based hydrophobic deep eutectic solvent (DES) for removal from its aqueous solutions. DES is synthesized by addition DL-menthol lauric acid (dodecanoic acid) molar ratio 2:1. Liquid–liquid equilibria (LLE) experiments are then performed evaluate performance extraction such as ethanol, 1-propanol, 1-butanol. LLE...

Five- and six-membered heteroaromatic nitrogen compounds play an inhibiting role in the hydrodesulfurization of diesel oil. In this work, ionic liquids (ILs) are used as green solvents to remove such by liquid−liquid extraction (LLE). Approximately 168 ILs comprising cations which include 1-ethyl-3-methylimidaozlium [EMIM], 1-ethylpyridinium [EPY], 1-ethyl-1-methyl pyrrolidinium [EPYRO], 1-ethyl-1-methylpiperidinium [EMPIP], 4-ethyl-4-methyl morpholinium [EMMOR],...

Deep Eutectic Solvents (DESs) are gaining more interest as low-cost extraction media. Looking at its vast opportunity, the current work explores of alcohols namely ethanol, 1-propanol, and 1-butanol from aqueous phase using two novel hydrophobic DES 303.15 K 1 atm. The preparation possess a common HBA (Hydrogen Bond Acceptor) with HBD Donor such organic acids i.e., lauric acid decanoic acid) certain proportion. Ratios 2:1 1:1 were used for synthesizing menthol: (DES-1) menthol/decanoic...

Deep eutectic solvents (DESs), being ionic liquid (IL) analogues, are easy to prepare, cost-effective, recyclable, and biocompatible have low toxicity. Hydrophobic deep (HDESs) composed of natural compounds highly effective in the extraction micropollutants (metal ions, pharmaceuticals, so on) from an aqueous stream. In this work, formation mechanism dl-menthol carboxylic acid (acetic, butanoic, hexanoic, octanoic, nonanoic, decanoic, dodecanoic acid) based DESs a molar ratio 1:1 has been...

Separation of aliphatic and aromatic compounds was studied using the high molecular weight trihexyl-tetradecyl-phosphonium cation (thtd-Ph) based ionic liquids (ILs) with anions chloride [Cl], tetrafluoroborate [BF4], bis(trifluoromethane sulfonylimide)[(Tf)2N]. Infinite dilution activity coefficients (γ∞) for these novel solvents have been measured at T = (308.15, 318.15, 328.15) K, gas−liquid chromatography. The solutes were normal alkanes (pentane, hexane, heptane, octane), alkenes...

Abstract Ionic liquids with their limitless combination of cations and anions can offer an optimal solvent for a specific purpose. But not all corresponding experimental studies are possible as they will be time consuming expensive. A judicious screening the various solvents is required to select proper ionic liquid. Conductor‐like model (COSMO) along its extension real used these predictions. In this work, modified version COSMO_LL has been predict liquid–liquid equilibria (LLE) 32 ternary...
