TL;DR: In this article, a 12:1 molar ratio of methanol to oil, addition of 8% CaO catalyst, 65°C reaction temperature and 2.03% water content in methanols gave the best results, and the biodiesel yield exceeded 95% at 3

TL;DR: In this paper, the performance of transesterification of soybean oil to biodiesel using SrO as a solid base catalyst was studied and the reaction mechanism was proposed and the separate effects of reaction temperature, molar ratio of methanol to oil, mass ratio of catalyst to oil and repeated experiments were investigated.

TL;DR: In this article, physical and chemical characterizations of calcium methoxide were investigated to assess its performance as an excellent solid base catalyst using some instrumental methods, such as BET surface area measurement, scanning electron micrographs and particle size distribution.

TL;DR: In this article, the authors proposed the use of calcium ethoxide as a catalyst for the transesterification of soybean oil to biodiesel with methanol and ethanol, and the experimental results showed that the optimum conditions are a 12:1 molar ratio of methanols to oil, the addition of 3% Ca(OCH2CH3)2 catalyst, and a 65 °C reaction temperature.

TL;DR: In this article, a transesterification of soybean oil with ethanol using NaOH as a catalyst is described, and phase diagrams and tie lines of the fatty acid ethyl esters + ethanol + soybeans oil system were drawn in the range from (300.15 to 343.15) K.
