Oprescu, Elena-Emilia published the artcileSynthesis and evaluation of levulinic ester as biodiesel additives, COA of Formula: C7H12O3, the main research area is TiO2 La2O3 levulinic ester biodiesel additive.
In this study, the SO42-/TiO2-La2O3-Fe2O3 catalyst was prepared and tested in the conversion of fructose to Et levulinate. The catalyst was characterized from the point of view of the textural anal., FT-IR anal., acid strength distribution, X-ray powder diffraction and pyridine adsorption IR spectra. The influence of the reaction parameters on the Et levulinate yield was study. The maximum yield of 37.95% in levulinate esters was obtained at 180°C, 2 g catalyst and 4 h reaction time. The effect of Et levulinate addition to diesel-biodiesel blend in different rates, i.e, 0.5, 1, 2.5, 5 (w.t %) on d., kinematic viscosity and flash point was evaluated and compared with the European specification.
Revista de Chimie (Bucharest, Romania) published new progress about Biodiesel fuel. 539-88-8 belongs to class esters-buliding-blocks, name is Ethyl 4-oxopentanoate, and the molecular formula is C7H12O3, COA of Formula: C7H12O3.
