Abstract
The objective of this work was to produce methyl biodiesel from Bombacopis glabra (B. glabra) oil degummed with H3PO4. The methyl biodiesel was prepared in an alkaline medium, and characterized by physico-chemical parameters, thin-layer chrmatograghy (TLC), gas chromatograph (GC), (Nuclear magnetic resonance of hydrogen (H-NMR), thermogravimetry and infrared analysis. The physico-chemical parameters of biodiesel were in accordance with the limits established by National Agency of Petroleum, Natural Gas and Biofuels (ANP) Resolution 45/2014, except oxidation stability, where it was corrected with the addition of antioxidants such as TBHQ and BHT.
Highlights
The research in biodiesel area has intensified in recent years, due to the environmental advantages it presents compared to petroleum diesel
Bombacopsis glabra oil, which was extracted at room temperature and degummed with H3 PO4, presented an acidity level suitable for conversion into biodiesel
Methyl biodiesel was obtained for the first time from B. glabra oil through the transesterification process, using the base catalyst (NaOH) with the superb conversion efficiency of triacylglycerols to methyl ester
Summary
The research in biodiesel area has intensified in recent years, due to the environmental advantages it presents compared to petroleum diesel. Since it is free from sulfur and aromatic compounds, it emits lower particulate content, such as hydrocarbons (HC), carbon monoxide (CO). A tropical country, has a great potential for biodiesel production, possessing large areas of productive land and a large variety of oilseed to obtain vegetable oils [3]. In some regions of the country, there are plantations with a high yield potential. The study of native plants of each region is essential to evaluate their productive potential, to aggregate value to these species, and contribute to generate employment and income to the rural population
