Leucaena Oil Functionalized With Osmium Tetroxide as a Precursor for Polyol‐Based Polyurethane

Journal of Polymer Science, EarlyView.
Leucaena leucocephala seed oil is converted into a hydroxyl‐functional biopolyol through OsO4‐mediated dihydroxylation. The resulting biopolyol shows a hydroxyl number of 160–175 mg KOH g−1 and is successfully used to produce flexible, open‐cell polyurethane foams, highlighting a renewable route for converting underutilized biomass into value‐added ...

Lipase Catalyzed Transesterification of Tung and Palm Oil for Biodiesel [PDF]

Linköping Electronic Conference Proceedings, 2011
The tung oil and palm oil were subjected to enzymatic transesterification. Immobilized lipase (Novozyme 435) was used at 10 % w/v vs. oil. The reactions were conducted at 40C to 60C with methanol and ethanol at a molar ratio of 1:3 for 24 h ours. Temperature was found critical for the conversion efficiencies.
