Sažetak
Additives are necessary for the use of diesel fuel and due to the growing concerns of the scientific community regarding environmental protection, it is desirable to consider the possibility of using materials of natural origin in their synthesis. In the past period, the proportion of sulfur that may be present in diesel fuel has been significantly reduced, which has negatively affected its lubricity, so it is necessary to focus the research on the synthesis of bio-additives that would improve it. In this work, bio-additives were synthesized from lauric acid and a branched polyol, pentaerythritol. The used lauric acid is a saturated acid containing twelve carbon atoms and it can be obtained from renewable sources such as coconut and palm oil. On the other hand, pentaerythritol is a polyol, an alcohol containing more than one hydroxyl group in the structure, obtained by an aldol reaction from formaldehyde, a product of metabolism, and acetaldehyde. Preliminary tests have shown an improved lubricity of diesel fuel additivated with 2000 ppm of the synthesized bio-additive by up to 40 %. In the standard test EN 12156-1 the wear scar diameter was reduced from 571 μm to 360 μm which satisfies the values for use in motor vehicles according to EN 590.
