Euonymus maackii Rupr. Seed oil as a new potential non-edible feedstock for biodiesel

2019

Abstract In this study, Euonymus maackii Seed oil (EMSO) was exploited and evaluated for the first time as a new non-edible oil feedstock for preparation of biodiesel. The EMSO yield was 41.06 ± 2.68 wt%. The fatty acid compositions of EMSO involved palmitoleic acid (2.01%), palmitic acid (14.5%), stearic acid (3.1%), oleic acid (49.8%), linoleic acid (29.3%), 11-Eicosenoic acid (0.1%) and arachidic acid (0.07%). Microwave-assisted transesterification with methanol provided a high conversion yield in short duration under low temperature. The 2.0 wt% of catalyst amount, 10:1 of methanol/oil molar ratio, 40 min of reaction time and 60 °C of temperature were found to be the optimum process condi…

Catalytic transesterification of Pistacia chinensis seed oil using HPW immobilized on magnetic composite graphene oxide/cellulose microspheres

2018

Abstract In the present study, magnetic composite graphene oxide/cellulose (GO/CM@Fe3O4) microspheres were prepared as support material, which are cost-efficient, non-toxic and environmental friendly. The microspheres with higher adsorption capacity were further modified using triethylene tetramine (TETA), and H3PW12O40 (HPW) was immobilized to form GO/CM-NH2@Fe3O4-HPW microspheres as heterogeneous catalyst for biodiesel production. The novel heterogeneous catalyst was characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), Brunauer-Emmett-Teller (BET) and X-ray diffractometry (XRD). For the first time, GO/CM-NH2@Fe3O4--HPW was applied in the tr…

Efficient extraction and preparative separation of four main isoflavonoids from Dalbergia odorifera T. Chen leaves by deep eutectic solvents-based ne…

2016

In this study, green and efficient deep eutectic solvent-based negative pressure cavitation-assisted extraction (DES-NPCE) followed by macroporous resin column chromatography was developed to extract and separate four main isoflavonoids, i.e. prunetin, tectorigenin, genistein and biochanin A from Dalbergia odorifera T. Chen leaves. The extraction procedure was optimized systematically by single-factor experiments and a Box-Behnken experimental design combined with response surface methodology. The maximum extraction yields of prunetin, tectorigenin, genistein and biochanin A reached 1.204, 1.057, 0.911 and 2.448mg/g dry weight, respectively. Moreover, the direct enrichment and separation of…
