The reason that we use isopropyl alcohol in the titration portion of the biodiesel prpcess is that isopropyl will not react substantially with the vegetable oil or the indicator, thus giving you a repeatable result.If you want to see what a titration yields with an alcohol that does react, use ethanol- you'll see the pH values move all over the place as the ethanol reacts with the vegetable oil (I think)). So, I think the answer is no.
