“…Nevertheless, the fatty acid profile of the sample was between the high‐oleic sunflower and corn oil, which could indicate that the mixture of both oils is intermediate. Consequently, the differences between the oxidative stability of the sample (7.4 hours) and high‐oleic sunflower oil could be due to the differences in the fatty acid profile and the natural antioxidant content, such as tocopherols (García et al, ; Ramalingam et al, ; Zhou et al, ).…”

“…Concerning additives, both natural and synthetic antioxidants are used, which scavenge free radicals that would attack unsaturated FAME, extending the storage time of biofuels (Dunn, ). According to the literature, many antioxidants are used for this purpose, especially butylated hydroxyanisole (BHA) and tert‐butylhydroquinone (TBHQ), which are aromatic compounds (Dunn, ; Kumar, ; Ramalingam et al, ; Saluja et al, ; Verma et al, ; Zhou et al, ). These antioxidants have been used in a wide range of concentrations, generally from 500 to 5000 mg·kg −1 (Dunn, ), being effective with regard to oxidation stability.…”

Biodiesel is an alternative to mineral fuels, with advantages such as biodegradability. However, this makes biodiesel unstable to oxidation. In this way, the use of natural or synthetic antioxidants is necessary. Although many studies have paid attention to the effect of these antioxidants on oxidation stability, not much literature about their effect of them on other properties (before and during storage) was found. The aim of this research study was to characterize biodiesel from corn and sunflower by adding two antioxidants, butylated hydroxyanisole (BHA) and tertbutylhydroquinone (TBHQ), in order to improve its oxidation stability. Moreover, the effect of oxidation on the parameters of biodiesel was studied by using extreme oxidation conditions to accelerate the oxidation process. Both antioxidants improved the oxidation stability of biodiesel, whereas some parameters were altered (viscosity and acid number), which could make this biofuel, if high concentrations of antioxidants are used, unsuitable for commercialization according to standards.Keywords BHA Á TBHQ Á Oxidation stability Á Viscosity Á Thermal analysis Á Fatty acid methyl esters J Am Oil Chem Soc (2020) 97: 201-212.

“…Some molecules have been synthesized and studied to improve at least two properties of biodiesel, the so-called multifunctional molecules. 31 Singh et al 32 synthesized a hindered phenolic Schiff base for biolube and Jatropha curcas, which improves the lubricity and oxidative stability of biodiesel. Molecules with antioxidant and NOx reduction activity, 33 as well as with anticorrosive and acidity reduction properties may be found in the literature, 34,35 13 C nuclear magnetic ressonance spectra (NMR) were obtained using a Varian VNMRS400 spectrometer, with a magnetic field of 9.4 T, 32 scans for 1 H spectra and 2000 scans for 13 C spectra, and deuterated chloroform (CDCl 3 ) as solvent.…”

New Schiff base compound N,N'-bis-(4-hexadecanate)-salicylethylenediamine (named IM) was synthesized, and characterized via infrared and nuclear magnetic ressonance spectroscopies. IM was tested as corrosion inhibitor and antioxidant in soybean biodiesel. Corrosion studies were developed with AISI 1020 carbon steel in a three-step accelerated corrosion assay and IM inhibitory activity was evaluated using microscopic techiniques: optical microscopy (OM), scanning electron microscopy (SEM) and atomic force microscopy (AFM). In 750 ppm concentration, IM showed better inhibitory activity compared to commercial compounds tert-butylhydroquinone and pyrogallol, reducing root-mean-square roughness (Rq) from 37.8 to 11.7 nm and peak-peak height (PP) from 454.1 to 120.2 nm after 8 days of immersion. Antioxidant studies were conducted using the PetroOXY equipment. In 250 ppm concentration, IM showed better antioxidant activity as metal chelator, reducing biodiesel oxidation induced by copper on biodiesel. In this concentration, IM increased the induction period from 3.0 to 5.8 h. Furthermore, the new Schiff base acts as an oxygen scavanger. This is a great property because it reduces oxygen concentration in biodiesel, reducing metal corrosion reactions.

“…Avase et al [15] studied the effect of Pyrogallol (PY) on performance and emission characteristics of biodiesel and results showed that pyrogallol enhanced the blend properties and has narrowed the gap between the properties of blend and that of diesel. Ramalingam et al [16] found out that antioxidants reduce the hydrogen free radicals in biodiesel which tends to reduce the NO x emissions which is also a major problem with the use of biodiesel. Celik et al [17] investigated the impact of magnesium additive based rape seed methyl ester on engine emission result shows that there is result in reduction of CO, THC and smoke emission while increase in NO x emission.…”

Rising level of pollution and extreme rate of depletion of fossil fuels has become a major issue in today's world which requires immediate measures for its prevention. Biodiesel is the potential answer to this threat to environment as being an extremely promising fuel given its adaptability of usage in currently existing engine modules. Out of various oil sources for biodiesel production (Jatropha, Pongamia, Neem, Mahua) Cotton seed oil is one of the prominent source for biodiesel production in India. The aim of this study to enhance the fuel quality of cotton seed biodiesel so that it can be used as an alternative fuel. Viscosity is an important indicator of progression of oxidation in biodiesel to be used in an engine. Viscosity and flash point of biodiesel is optimized with the help of anti-oxidant (pyrogallol) and by governing the adverse effects of oxidizing agent as metal contaminants of aluminium. The experimental investigation reveals that Cotton seed biodiesel (CB 20) with metal contamination there is decrease of 21.03% in brake thermal efficiency (BTE) and without metal contaminants there is decline of 11% was found as compared to diesel while brake specific fuel consumption (BSFC), was increased by 25.84% for CB 20 with metal contaminants and for CB 20 (without metal contaminants) there is increase in 10.73% as compared to diesel. There was a significant reduction in exhaust emissions including carbon monoxide (CO) and (CO 2) as for CB 20 value reduction for CO 2 was 41.35% and 38.27% for samples with and without metal contaminants. However, a 15.84% and 11.2% increase in oxides of nitrogen (NO x) emission was experienced for biodiesel mixtures for CB 20 with and without metal contaminants respectively as compared to diesel.
