2 hydroxyethyl acrylate hea

The synthesis and evaluation of MIL-101 particles is according to the literature37 (link). MIL-101 was synthesized by hydrothermal reaction of benzene-1,4-dicarboxylic acid (164 mg, 1 mmol), Cr(NO₃)₃·9H₂O (400 mg, 1 mmol), hydrofluorhydric acid (5 M, 0.2 mL, 1 mmol) in H₂O (4.8 mL, 265 mmol) at 220 °C for 8 h. The XRD results (Fig. 5a) proved the MIL-101 had been successfully synthesized. The evalution 2-Hydroxyethyl acrylate (HEA) with a purity of 96% and D-limonene with a purity of 95% were purchased from Tokyo Chemical Industry Co., Ltd. Analytical grades of ethanol, tetrachloroethylene, acetone and ethyl butyrate were purchased from Sinopharm Chemical Reagent Co., Ltd. All these materials were used without further purification.
