Complete the data table below with the values you measured in the experiment. Remember to include units and use proper sig figs.
Amount measured | |
Methanol | 8.01 mL |
Vegetable oil | 1.02 mL |
2. How many moles of biodiesel (methyl ester) is produced per mole of triglyceride?
3. What important step does calcium methoxide facilitate? Is the calcium methoxide used up in the synthesis?
4. Complete the data table below with the values you measured in the experiment. Remember to include units and use proper sig figs. Show work for all calculations below the table.
Mass of Graduated cylinder | volume of biodiesel | Mass of GC + Biodiesel | Mass of Biodiesel | Density of biodiesel | pH of Biodiesel | Presence of Intermediates? (y/n) |
50.30 g | 1.2 mL | 51.41 g |
5. Discuss the results of the pH and test for intermediates measurement. Was there a complete synthesis of biodiesel in your reaction? Support your conclusion with evidence from your experiment.
6. Compare and contrast the synthesis of biodiesel with the saponification of fatty acids performed last week. What similarities are there between the reactants? What type of reaction is each? What is the difference between the products?
