“…The refined high oleic sunflower oil can be used as lubricant in both textile and tannery industries. 30 Further, the oxidative stability of these structures can be improved by eliminating the bis-allylic hydrogen functionalities in the polyunsaturated methylene chain and making them a good candidate for the general biolubricant used in chain saws, brake fluid and transmission oil. 31 Castor oil methylester blended with diesel can be used for several industrial applications such as lubricity enhancer and also viscosifiers in preparing oil drilling fluids.…”

Biodiesel is a promising alternative among the different fuels put forward as a substitute for diesel fuel. One important issue in internal combustion engines is the lubrication of the equipments which are lubricated by the fuel itself. Previous studies have shown that biodiesel possesses excellent inherent lubricity. However, biodiesel is susceptible to oxidation reactions due to the presence of unsaturation in its moiety. These reactions are accelerated in the presence of oxygen and high temperatures and may alter the lubrication characteristics. In this particular research work, an investigation has been made to assess the impact of load, temperature, and biodiesel concentration upon friction and wear in the four-ball wear machine. The effect of individual parameter utilizing other biodiesels has already been presented elsewhere. The current study demonstrates the response of biodiesel and oxidized biodiesel with combined variation of operating parameters. The selected temperatures and loads were 45-60-75 C and 40-50-60 kg, respectively. The tests were conducted with diesel (B0), B20 (20% jatropha methyl ester by volume), B40, B100, and oxidized biodiesel. It was found that these variables not only individually but also collectively affect the tribological performance of biodiesel.

“…Only around 50 to 60% of used lubricants are properly recovered and discarded in an environmentally friendly way. erefore, lubricants originated from biomass could lead to a series of benefits to the environment if they are considered as substitutes to fossil compounds due to their increased degradability [3].…”

As increasing environmental policies constrains are imposed, the demand for biodegradable products also increases. Although vegetable oils present some properties that favor its use for formulation of a bio-based lubricant, its poor resistance to oxidation hinders its application as such. In this study, the thermo-oxidative stability of bio-based products was compared to petroleum-based lubricants and vegetable oils through the PetroOXY method. Chemical modifications in the ricinoleic acids were carried out using long-chain alcohols in esterification reactions. Acetates were obtained from ricinoleates with and without hydrogenation steps. Additionally, commercial antioxidants and phenolic compounds (saturated and unsaturated cardanol) obtained from cashew nut shell liquid were added to the synthesized samples with higher induction times. The results show that the chemically modified bio-based products exhibited improved oxidative stability (up to 6 times) and depressed pour point (−42°C) when compared to pure castor oil. Overall, the addition of antioxidants increased from 6 to 20 times the oxidative stability of the bio-based products. Propyl gallate and saturated cardanol showed higher efficiency for retarding the oxidative process of bio-based samples than the commercial antioxidants.

“…Recently, progress has been made in engineering high-performance biolubricants in crop plants. In high-oleic vegetable oils (HOSNO, high-oleic soybean oil (HOSBO), HOSFO, high-oleic rapeseed oil (HORSO), high-oleic castor oil (HOCAS), high-oleic peanut oil (HOPNO), HO canola, palm olein, cottonseed, meadowfoam and Lesquerella oil), all with a higher ratio of monounsaturate oleic to diunsaturate linoleic residues, a reduced tendency to oxidation is provided as well as improved heat stability [164,243,[250][251][252][253][254][255][256][257].…”

“…Continuous development ensures increased use of oils and fats as renewable raw materials in the chemical industry. The generation of transgenic sunfl ower lines with HO acid content is an example in which plant biotechnology has already provided new opportunities for bio-based lubricants and greases [255]. Despite its somewhat limited availability HOSNO (with >90 % C18:1) is considered as a commodity oil and is currently the best choice.…”
