“…Consequently, the ultrasound‐assisted LLE method allowed the extraction of volatile compounds having a high boiling point (>160°C) and a high log P (>3) as compared to the SPME method. These results were consistent with a previous work done on a fat‐free model food system (Cayot et al., ). Indeed, the higher the boiling point and the log P values, the higher the extraction yield of volatile compounds with the LLE.…”

“…The ultrasound‐assisted LLE was done as described by Cayot et al. () 5 g of sample, 25 ml of the extraction solvent (azeotrope “propan‐2‐one / cyclopentane” in a molar ratio of 59.55 / 40.45) and 100 μl of internal standard were strongly stirred for 5 min. Then, the flasks were placed in an ultrasound bath (Bransonic Mod 5210, Branson Europe B.V.) for 10 min at an ultrasound fixed‐frequency of 47 kHz ± 6%.…”

“…The challenge of green extraction is to "design extraction processes which will reduce energy consumption, allows use of alternative solvents and renewable natural products, and ensure a safe and high quality extract/product (Chemat et al, 2017).". Several works have been conducted to find "green extraction solvents" ( Armenta & de la Guardia, 2016;Cayot, Lafarge, Bou-Maroun, & Cayot, 2016;Li, Fabiano-Tixier, Ginies, & Chemat, 2014;Li, Fine et al, 2014) or "green method of extraction" (Filly et al, 2014;Sanchez-Prado, Garcia-Jares, Dagnac, & Llompart, 2015). LLE using the azeotrope "propan-2-one/cyclopentane" was reported as a suitable one for the extraction of volatile compounds (Cayot et al, 2016).…”

Some green extraction methods were selected and tested for the extraction of volatile compounds from different samples of the microalga Chlorella vulgaris: ultrasound‐assisted liquid–liquid extraction using environment‐friendly solvents (LLE) and solid‐phase microextraction (SPME). The obtained profiles of volatile chemical compounds were different. Only one molecule was found in common to both extractions. Using the SPME method, the main chemical classes of identified volatile compounds were sulfuric compounds, aldehydes, and alcohols. Using the LLE method, the volatile profile was more balanced with alkanes, fatty acids, terpenes, alcohols, and aldehydes. Multivariate data analyses permitted discrimination among samples. Additionally, the relationship between the physicochemical properties of identified volatile compounds and the methods of extraction was studied. The results showed that the LLE extraction allowed the extraction of volatile compounds having a high boiling point (>160°C) and a high log P (>3). The SPME method was more effective to extract volatile compounds with a low boiling point (<160°C) and a low log P (<3). It is thus necessary to combine several extraction methods to obtain a complete view of the volatile profile for microalgae samples.

“…Thus, the pervaporation of dichloromethane‐cyclopentane (DCM‐CP) and methylal‐cyclopentane (ML‐CP) mixtures through membranes from CR is reported in this work. The studied compounds are common solvents, refrigerants, and blowing agents 16–20 ; ML is also a chemical feedstock and intermediate in the production of synthetic diesel fuel 21,22 . The separation of the above mixtures by distillation appears complicated by the similarity of their normal boiling points, 23 which are 39.9, 42.2, and 49.3°C for DCM, ML, and CP, respectively.…”

Chloroprene rubber (CR) has been commonly applied in various branches of the industry but its application in selective layers of pervaporation membranes remains overseen. To survey its applicability, we report on the pervaporation of two close‐boiling azeotrope‐forming systems of common solvents, blowing agents, adjuvants, and refrigerants, namely, dichloromethane‐cyclopentane (DCM‐CP) and methylal‐cyclopentane (ML‐CP). Vulcanizates having the form of thin films (66 ± 5 μm) have been prepared from the crystallization‐resistant (WRT) polychloroprene by using nanoparticles of ZnO and MgO. Mechanical and thermal properties have been characterized using dynamic mechanical analysis (DMA) and thermogravimetry analysis, spectral properties using ATR‐FTIR. Plasticization has been assessed by measuring DMA characteristics for the CR films exposed to vapors of the studied compounds. The CR films are preferentially permeable to DCM and ML over CP, break the respective azeotropes, and show comparable selectivity ranging from 1.1 to 1.7 for DCM‐CP and from 1.0 to 1.8 for ML‐CP. Importantly, plasticization of the CR membranes by DCM and ML enhances the selectivity and, simultaneously, the transmembrane flux. Overall, we show that membranes from CR enable selective and intensive pervaporative recovery of halogenated hydrocarbons from their mixtures with hydrocarbons, which is relevant, for instance, for the recycling of blowing agents.
