  30. 30. Conclusion<br /> We have confirmed that PmAP-Na catalyst isn’t a good heterogeneous catalyst for the transesterification due to the fact that the catalyst can dissolves in methanol. There could be many human errors. For example, the amount of substance added is wrong, the calculation is wrong, etc.<br /> As shown in the result, the higher the amount of NaOH, the more yield the substance tends to have. Although the fact that the catalyst “5mmol of NaOH + 5mmol of PmAP” gain lower yield than the catalyst “3.75mmol of NaOH + 5mmol of PmAP” could be the result from the human errors we had done.<br />
