To recover 2-ethyl-1-hexanol and 1,2-propanediol from waste polyester alcoholysis products, liquid−liquid equilibrium (LLE) data for the ternary system of 2ethyl-1-hexanol + 1,2-propanediol + (water, n-heptane) at different temperatures (303.2, 313.2, and 323.2 K) were studied at 101.3 kPa. The distribution coefficient (D) and selectivity coefficient (S) were used as indicators to assess the separation effect. The NRTL and UNIQUAC models were used to correlate the experimental data and the root mean square deviation (RMSD) values were calculated to be less than 0.75 and 0.97%, respectively. Finally, the consistency between the experimental data and the regression parameters was verified using the GUI-MATLAB tool. σ-Profiles are used to discuss the interactions of substances in this work. It was found that both extractants could separate and extract 2-ethyl-1-hexanol and 1,2-propanediol effectively, with water being more effective.

“…[14] Vegetable oil-based renewable resources such as ESO, glycerol and OA are used as a precursor to prepare macromolecular polymers by chain extension reaction in several fields, such as biomedicine, organic gel production, additive manufacturing and green compatibilizers. [15,16] Chen et al [17] prepared sisal microcrystalline cellulose (MCC)/natural rubber (NR) composites with (OA, γ-aminopropyltriethoxysilane (KH550)) and bis-γ-(triethoxysilylpropyl)-tetrasulfide (Si69) as modifiers. The results of molecular dynamics simulation and experimental results showed that the OA-cellulose has a better interaction with NR than KH550-cellulose and Si69-cellulose.…”

The fabrication of composites of two or more materials with different polarities requires the use of compatibilisers to improve interface properties. However, most compatibilisers used for industrial production are derived from the cracking products of petroleum, which is a limited resource susceptible to price fluctuations and pollutes the environment. In this study, a new compatibiliser derived from renewable plant‐oil‐based products, ESO–G–OA, was designed and synthesized using epoxy soybean oil, oleic acid, and glycerol. Scanning electron microscopy results showed that ESO–G–OA can effectively improve the dispersion of CaCO3 in a recycled high‐density polyethylene (reHDPE) matrix and reduce the interfacial gap between the two phases. The analysis of the mechanical properties showed that the ESO–G–OA‐modified composite has higher tensile and impact strength than unmodified samples. The ESO–G–OA modification improved the thermal stability and melt flow of the composite and reduced the energy consumption during processing. Moreover, the excellent compatibility of ESO–G–OA can improve the comprehensive properties of CaCO3/reHDPE composites, compensating for the performance reduction caused by the multiple processing steps necessary to obtain reHDPE. This confirmed that ESO–G–OA has promising application prospects in the production of composites requiring compatibilisers.
