Can Bases Be Used to Make Biodiesel Fuel?

💡 The Answer

• Biodiesel is produced via transesterification, where oils react with methanol in the presence of a base catalyst.
• Common base catalysts include sodium hydroxide or potassium hydroxide, which accelerate the reaction.
• The process converts triglycerides into fatty acid methyl esters (biodiesel) and glycerol.
• Basic catalysts are favored for their high activity and low cost, but require anhydrous conditions to avoid soap formation.
