“…In this context, vegetable oils represent suitable substitutes for replacing conventional mineral oil-based lubricants due to their biodegradability and non-toxicity. In fact, compared to mineral oils, biolubricants have a higher flash point, viscosity index and lubricity, and lower evaporative loss [1,2]. On the other hand, the applicability of biolubricants is partially limited due to their thermo-oxidative hydrolytic instabilities, as well as their low-temperature fluidity.…”

This work deals with the preparation of biolubricant basestocks through the ring-opening reaction of epoxidized soybean oil (ESO) by alcohols in presence of solid acid catalysts (SAC-13 resin). To this end, different experimental runs were carried out in a lab-scale reactor, analyzing the effect of the alcohol (methanol, ethanol, 2-propanol, 2-butanol), catalyst mass loading (from 1 to 10 wt % with respect to the oil mass) and operating temperature (60-90 • C). The main focus of investigation was oxirane conversion. The study was complemented by FT-IR, 1 H NMR and kinematic viscosity characterization of the different products of the ring-opening reaction. Experimental conversion data were fitted through a suitable kinetic model. Values of the best-fitting parameters in terms of rate constant, activation energy and catalyst reaction order were obtained, and were potentially useful for the design of an industrial process.

“…A higher viscosity index indicates small changes in viscosity in large range of temperature, whereas low values indicate high variations of viscosity 30 . The bio-lubricants based on epoxidized oils have higher VI (about 155), meaning good efficiency at high temperatures, keeping its thickness 31 . The conversion value (C) of unsaturation bonds was 59.65%.…”

The new generation of cutting fluids should have some characteristics, such as low toxicity and biodegradability. A bio-cutting fluid emulsion are an excellent option because they present those properties, as well as good mechanical performance. The present study aims to investigate the lubricity of O/W emulsions (cutting fluid emulsion), varying the concentration of anionic surfactant (1%, 2.5% and 5%) and epoxidized oil (5%, 10%, 15%, 20% e 25%). A sunflower oil was chemically modified by epoxidation reaction, then its viscosity, iodine and oxirane index, density, and acidity were characterized. The performances of the emulsions were evaluated using a tribometer HFRR (High Frequency Reciprocating Rig), under hydrodynamic lubrication conditions. The ball wear scars were analyzed using an optical microscopy. The results showed that a low concentration of surfactant promote friction and wear reduction. Based on the tribological performance, the emulsions with 5% and 10% of epoxidized oil are more suitable.

“…It are often concluded that vegetable oils have potential as lubricants. [10] Over the past decade the landscape of the lubrication marketplace has considerably modified thanks to a combination of environmental, health, economic and performance challenges. To handle these challenges it's essential to develop and use lubricants that come back from natural resources.…”

castor oil having competent lubrication properties are going to be present during this work with blends of mahua oil and antiwear characteristics with comparison against fossil oil lubricant for tribological properties. Analysis on bio lubricant within the field of automotive applications with experimentation on four ball tester for antiwear characteristics with numerous blends of castor and mahua oil are studied during this work. During this Paper result of addition with the nanopartical hexagonal boron nitrate (hBN) in Castor and Mahua oil mix for improve the tribological properties of lubricants. These nano particle were added in blended oil at totally different proportions (0.5%,1%, and 2% wt. %). This investigation is beneficial for comparing the result of additives on bio lubricants properties like wear, coefficient of friction with commercial lubricant SAE 10W30 engine oil. The analysis of tribological properties take a look at was calculated on a four ball oil testing machine per ASTM D 4172 B. Result show that the every set of Nanoparticle considerably reduces the friction coefficient and wear of friction pairs. The damage surfaces were analyses by scanning microscope (SEM).
