===** Corn Biodiesel Synthesis ** === Corn biodiesel was achieved by reacting 5.0g, or 5.3mL, corn oil, 0.856 g diphenyammonium tosylate, and 4.7 mL methanol. This mixture was reacted at 140 ° C for 20min. Two washing of deionized water were used in order to remove the acidity of the biodiesel and about 1.0g of calcium chloride to remove excess water.

===** Soy Biodiesel Synthesis ** === Soy biodiesel was achieved by reacting 5.0g, or XmL, Soy oil, 0.X g diphenyammonium tosylate, and X mL methanol. This mixture was reacted at 140 ° C for 20min. Two washing of deionized water were used in order to remove the acidity of the biodiesel and about 1.0g of calcium chloride to remove excess water. ****

=** WEEK 2 ** =

After our week 1 results, we decided to forgo further testing with corn oil and soy oil and focus mainly on waste oil. The reason why we chose to focus on waste oil is because further advancement made with waste oil would be more efficient and rewarding than using corn oil or soy oil.

The tweak that we decided to make was to change the percentage of catalyst used in our synthesis. In our week 1 experiments, we ended up using about 50% catalyst in our biodiesel synthesis' so we definitely wanted to reduce that amount. Thach informed us that Tuesday's lab group were getting 100% yields with just 5% catalyst so we decided to work off their results and attempt to further improve it. To figure out the limits of cataylst most optimal, we decided to test the maximum and minimum of catalyst. We decided on using 4.5% and 5.5% of catalyst in our biodiesel synthesis'.

===** 4.5% Catalyst Biodiesel Synthesis ** ===


Biodiesel was achieved by reacting 6.5g, or 7mL, waste oil, 0.1109 g diphenyammonium tosylate (4.5%), and 3.0 mL methanol. This mixture was reacted at 140 ° C for 20min. Two washing of deionized water were used in order to remove the acidity of the biodiesel and about 1.0g of calcium chloride to remove excess water.

===** **5.5% Catalyst Biodiesel Synthesis** ** === Biodiesel was achieved by reacting 6.5g, or 7mL, waste oil, 0.112 g diphenyammonium tosylate (5.5%), and 3.0 mL methanol. This mixture was reacted at 140 ° C for 20min. Two washing of deionized water were used in order to remove the acidity of the biodiesel and about 1.0g of calcium chloride to remove excess water.
