“…The least percentage of 20.54 ± 0.2% was found with ethanol due to their higher polarity and solubility in water which declined the bio-oil yield. The results obtained in this research were in line with the results of the other researchers 8,17,20,[24][25][26][27] , are reported in Table 2.…”

The present study explores the methodology for the synthesis of bio-oil from waste trichosanthes cucumerina seeds by the solvent extraction method. It investigates the yield percentage, concentration of free fatty acids and acid contents in the extracted bio-oil. Effects of size of the crushed seeds, moisture content, extraction time, solvent to seed ratio and extraction temperatures were examined. The non-polar hexane solvent resulted in a higher percentage of oil yield (28.4 ± 0.4%) for the crushed seed size of 0.21 mm, 6% moisture content, 270 min extraction time, 68 °C temperature and 6:1(ml/g) of solvent to seed ratio. The synthesized bio-oil was characterized using Fourier Transform Infra-Red spectrum and Gas Chromatography–Mass Spectroscopy analysis. The properties of the bio-oil and biodiesel were assessed according to the American Society for Testing and Materials and the Association of Official Analytical Chemists standards. The obtained methyl-ester by trans-esterification process results in the fuel properties closer to the conventional fuel. Thus, Trichosanthes cucumerina bio-diesel can be used as a potential substitute.

“…However, we could not find any systematic data available on the overall production of the pods per tree or in a given region or country. The various parts of the plant, namely, leaves, flowers, bark, pods, fruits, roots, pulp, and seeds contain vast and still unexplored riches of phytochemicals with high medicinal potential. , Abraham et al had reported the transesterification of the Cassia fistula seed oil with methanol and evaluated its methyl ester as biodiesel. As far as we are aware, the oil extracted from the seeds of Cassia fistula or its epoxidized derivatives have not been tried for their plasticization effect.…”

The soft poly(vinyl chloride) (PVC) films were prepared by a solution casting method using the epoxidized form of the oil (ECFSO) extracted from the seeds of Cassia f istula (a nonedible source), dioctyl phthalate (DOP), and DOP + ECFSO mixtures as plasticizers. The plasticization effects were evaluated in terms of thermal and mechanical properties, wide-angle X-ray scattering (WAXS) measurements, migration, and volatility of the plasticizer from the films. The use of ECFSO or its binary mixtures with DOP as plasticizers resulted in better thermal stability, improved mechanical properties, and a drastic decrease in the glass transition temperature (T g ) of the films as compared to DOP plasticized ones. The WAXS profiles showed no significant change in the order of the arrangement of PVC chains, and therefore the plasticization effects are mainly attributed to the enhanced chain mobility. The detailed analysis of the ATR-FTIR spectral measurements on the PVC films revealed major changes in the stretching frequencies of C�O of the plasticizers and HC−Cl of the PVC chains. Density functional theory (DFT) calculations and their careful analysis clearly establish the presence of hydrogen bond type interactions of the hydrogens of the −CH 2 Cl units of the hydrogenated repeat unit of the PVC with carbonyl and epoxy groups of the ECFSO plasticizer. Due to these hetero interactions, the migration of the plasticizer to the surface and solvent phase was found to be the lowest. The ECSFO based plasticizers have a good potential to partly or fully replace the DOP for producing high performing and environmentally safe PVC soft films.

A blend of radish oil (RO) and apricot kernel oil (AKO) was transesterified with methanol, ethanol, and their equivalent mixture, to yield methylic biodiesel (MBD), ethylic biodiesel (EBD), and methylic/ethylic biodiesel (MEBD), respectively with the refining of the so-developed fuels through adsorption onto the activated carbon prepared by ZnCl 2 activation of apricot shells. The best conversion of RO-AKO blend to MBD (96.12 ± 1.25%) and MEBD (94.23 ± 2.22) was attained at KOH concentration, 0.75% w/w of oil, alcohol/oil molar ratio, 6/1, mixing intensity, 600 rpm, reaction temperature, 60°C, and 45-min reaction period, whereas the best conditions that produced the highest yield of EBD (95.19 ± 2.0 %) were KOH concentration, 1.0 KOH % w/w of oil, ethanol/oil molar ratio, 8/1, mixing intensity, 600 rpm, reaction temperature, 65°C, and 75-min reaction period. The Fourier-transform infrared spectroscopy and 1 H nuclear magnetic resonance confirmed formation of the alkyl esters from the RO-AKO blend. The quality of MBD, EBD, and MEBD obtained from the RO-AKO blend was evaluated and found comparable with the American Society for Testing and Materials (ASTM) D6751 standards. Additionally, blending of MEBD with petrodiesel was possible, and properties of the blends were in accordance with those established by ASTM D7467-17. The methanolysis of the RO-AKO mixture followed the pseudo-first-order kinetics with activation energy of 27.27 kJ mol −1 . In conclusion, the RO-AKO mixture could be lowcost feedstock for biodiesel production. Moreover, apricot shells could be exploited as a priceless and suitable adsorbent for the adsorption of impurities found in the crude alkyl esters for its high surface area.KEYWORDS radish oil-apricot kernel oil blend, alcoholysis reaction, purification by activated carbon, fuel properties assessment, identification of biodiesel, kinetics
