Can biodiesel be made using an alcohol other than methanol?
For instance, if you had a mixture of methanol and ethanol or isopropanol, would you be able to use it to separate the glycerine? I ask because i need to extract glycerine from vegetable oil to make tinctures for teetotalers and i may not be able to obtain pure methanol.

methanol is sold hardware stores as it is a paint solvent. Methanol is the cheapest.
95% pure ethanol is called everclear in liquor stores.
I would think that using methanol or isopropyl alcohols would be poisionous.
um not sure about the teetotalers part but you can run a diesel engine off of pure vege oil provided you heat it before it hits the engine (to improve the viscosity) there are several groups of small companies making such devices and selling them on line. all you have to do once it’s installed is filter the free oil you acquire and add it to your tank. viola! no nasty chemicals to deal with
While looking closely at biodiesel fuel, you will find that its chemical and physical properties are extremely similar to all of the petroleum based diesel fuel, in relationship to its operation within the diesel or compression ignition engines. Because of this, biodiesel may be used within diesel engines without all of the other expensive alterations to the fuel system or engine.
