Revisiting Securidaca longipedunculata Seed Oil: Applying NMR and Mass Spectroscopy to Confirm the Presence of 2‐Acetyl‐1,3‐Diacyl–sn‐Glycerols and Conjugated Hydroxydienoic Fatty Acids

Journal of the American Oil Chemists' Society, Volume 103, Issue 11, Page 1373-1383, November 2026.
The manuscript confirms and expands on previous reports concerning the presence of unusual conjugated hydroxydienoic fatty acids and acetyl‐TAG in the seed oil of Securidaca longipedunculata. The location of acetate only at sn‐2 of TAG was conclusively shown by high resolution NMR and hydroxy seed fatty acids are characterized.

Enzymatic synthesis of acylglycerides from agroindustrial residues: process design and simplified techno‐economic assessment

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1821-1834, July/August 2026.
Abstract This study developed an enzymatic process to add value to palm oil fatty acid distillate (PFAD) and glycerol, resulting in the production of monoacylglycerides (MAG) and diacylglycerides (DAG). The biocatalyst loading (Novozym 435) and molar ratio of reagents were evaluated to obtain a suitable reaction condition in terms of space–time yield ...

Synthesis and Characterization of Trimethylolpropane Based Esters as Green Biolubricant Basestock

Biointerface Research in Applied Chemistry, 2021
Bio-based lubricant is crucial to be developed considering the toxicity risk, climate change, energy security, and green-environmental approach. In this work, trioleate trimethylolpropane (TOTMP) (1) was synthesized through the esterification between trimethylolpropane (TMP) and oleic acid (OA) using a sulfuric acid catalyst.

Synthesis of trimethylolpropane trioleate by using stannous oxalate catalyst

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 3, Page 1587-1595, May/June 2026.
Abstract This study was conducted to synthesize trimethylolpropane trioleate (TMPTO) using a stannous oxalate catalyst and investigate the dependence of the esterification rate on reaction variables. The highest esterification rate of approximately 99% was achieved at a 2.75:1 oleic acid/trimethylolpropane, 1.5% catalyst amount, 180°C reaction ...
