The aim of this study was to demonstrate the use of thermogravimetric analysis (TGA) as a potential screening method for monitoring biodiesel production by transesterification of soybean oil with methanol. Soybean oil and commercially available biodiesel were mixed in varying proportions by weight as standards. In addition, mixtures of different biodiesel/soybean oil ratios were also created b…
A promising route for the production of biodiesel (fatty acid methyl esters, FAMES) via transesterification of soybean oil (SBO) and poultry fat with methanol in quantitative conversions at room temperature has been developed using nanocrystalline calcium oxides as catalysts. Under the same conditions, laboratory-grade CaO gave only 2% conversion in the case of SBO, and there was no observab…
A promising route for the quantitative transesterification of soybean oil (SBO) with methanol to biodiesel (FAMES) at room temperature is described using the Merrifield resin-supported catalyst resin-N3dP(MeNCH2- CH2)3N. This catalyst was recycled 11 times, although its activity decreased with time. Factors possibly responsible for catalyst deactivation are presented. Interestingly, the poly…
