“…A sigmoid curve was obtained where %E was the lowest at pH eq 2.5 and it increased sharply from 3.0 to 4.0 before it achieved its maximum at 4.5 to 5.4. It was discovered that this finding was similar to those reported by Oshima et al [8] for Cu 2+ extraction with D2EHPA. By considering a dimeric form of D2EHPA in used cooking oil, the general equation for the Cu 2+ extraction can be expressed as [9]: (2) Where is D2EHPA in the dimeric form and is the number of D2EHPA molecules that take part in the reaction.…”

Abstract. The aim of this work was to study the extraction behaviour of Cu 2+ ions from aqueous solution with used cooking oil-based organic solvent. The used cooking oil-based organic solvent was composed of di-2-ethylhexylphosphoric acid (extractant), tributylphosphate (phase modifier) and used cooking oil (diluent). Effects of equilibrium pH (2-6), extractant concentration (10-100 mM) and operating temperature (25-47 o C) on Cu 2+ ion extraction from aqueous solution were investigated. It was found that used cooking oil-based organic solvent is a potential green and low-cost organic solvent for Cu 2+ ion extraction from aqueous solution.

“…Another research area in which CPME has been successfully used is the extraction of base metal ions. Oshima et al [69] reported the extraction of transition metal ions by using di-2-(ethyl-2-hexyl)phosphoric acid (D2EHPA, one of the most frequently used acidic extractants )d iluted in CPME. An extraction order in CPME (quantified by atomic absorption) of Fe III > Zn II > Cu II % Mn II % Ca II > Co II % Mg II % Ni II was comparable to a previously reported study that used kerosene.…”

The quest for sustainable solvents is currently a matter of intense research and development, as solvents significantly contribute heavily to the waste generated by chemical industries. Cyclopentyl methyl ether (CPME) is a promising eco‐friendly solvent with valuable properties such as low peroxide formation rate, stability under basic and acidic conditions, and relatively high boiling point. This Review discusses the potential use of CPME for applications in biotechnology (e.g., biotransformations, as solvent or cosolvent), biorefineries, and bioeconomy (e.g., for furan synthesis or as an extractive agent in liquid–liquid separations), as well as for other purposes, such as chromatography or peptide synthesis. Although CPME is currently produced by petrochemical means with a remarkably high atom economy, its biogenic production can be envisaged from substrates such as cyclopentanol or cyclopentanone, which can be derived from furfural or from (bio‐based) adipic acid, respectively. The combination of the promising properties of CPME as a (co)solvent with a future (economic) biogenic origin would be advantageous for setting strategies aligned with the sustainable chemistry principles.

“…Therefore, the authors examined the potential of CPME as a solvent in liquid-liquid extraction processes for metal ions. Recently, extraction of transition metal ions such as Cu (II) and Ni(II) using di-(2-ethylhexyl) phosphoric acid (D2EHPA) in CPME has been studied [5]. The extraction equilibrium constant in CPME as the solvent is slightly reduced compared with that in dodecane.…”

Recently, cyclopentyl methyl ether (CPME) has found use as a commercially available solvent for various applications. As CPME shows better properties such as more hydrophobicity, less solublity in water, less volatility, and more stablity compared with typical ethereal solvents, it could be used as a diluent or an extractant in liquid-liquid extraction systems. In the present study, CPME was found to be useful for the extraction of Au(III) in hydrochloric acid media. Extraction of Au(III) increased with as increase in the hydrochloric acid concentration. Au(III) was selectively extracted using CPME from other precious metal ions and base metal ions. From the result of the dependency of the Au(III) concentration, CPME can load at least 0.93 g/dm 3 Au(III). Extracted Au(III) was quantitatively stripped from CPME using 0.1 M aqueous thiourea solution. As the solubility of water into CPME is much smaller than that into alcohols such as 1-hexanol, CPME is more favorable as an extractant for Au(III) in hydrochloric acid media.
