A process for the preparation of diesel biofuel of sunflower oil involves processes of filtration with separation of attendant impurities, neutralization of free fatty acids, oil washing with salt solution and water, decontamination and reesterification. Sunflower oil with content of free fatty acids is used, and neutralization thereof is performed by three-stage esterification with strong sulphuric acid with constant stirring with separation of water and alcohol. Methanol and sulphuric acid is fed for reesterification with addition of methanol and catalyst.
