According to the formula, you should be adding half the methoxide after you have mixed in the sulphuric acid.
Heat and stir the mixture after adding sulphuric acid for 50 min then stop heating let mix for 1.5 to 2 hours. Then add half of the methoxide mix for 5 min then let settle overnight. I believe the methoxide, at this point, stops the esterification process. The next day, heat up to 55 C and add rest of the methoxide to transesterify, turn off heat, and mix for 1 hour then let settle. You will see separation. IF you do not add the methoxide after the sulphuric acid the esterification process will not stop and you might get some reverse-esterification. Not good!! I also understand that the first stage isn't really necessary with pure veggie oil. Only really needed if there are animal fats in the solution (trans fatty acids).
