“…The manufacture of biologically based products that are environmentally friendly and biodegradable using natural materials as substrates increasingly becoming an interesting field of study (Thanaphorn et al, 2018). The demand for many ecologically friendly and sustainable alternatives to current practices continues to attract maximum focus and attention in light of growing global climate change issues and the depletion of oil sources (Sukirno et al, 2019). For instance, studies have revealed that 20% of the 5.2 million metric tons of lubricant used each year in Europe are discharged into the ecosystem, and 1 kg of said mineral oil has the potency to contaminate huge and significant volumes of water (Godfred et al, 2021).…”

This research aimed at developing a process optimization of biolubricant production that will be environmentally eco-friendly. Greater concern has been focused on the use of solid-base catalysts, such asalcium oxide from limestone, for the transesterification of vegetable oils. Limestone was pretreated and calcined to 900 °C for 5 hours to obtain calcium oxide (CaO). The tropical almond seed oil was extracted from the tropical almond seeds using the soxhlet extraction method with a yield of 53.91%. The biolubricant was produced via double transesterification of tropical almond seed oil with methanol andrimethylolpropane (TMP) under reflux at different reaction conditions. Optimization of process parameters for the transesterification of tropical almond seed oil was determined using a response surface based on Box-Beinkhen design. The optimum yield of the biolubricant, 81.9%, was achieved at a temperature of 150oC, catalyst dose of 0.75 %wt and reaction time of 3 hours, respectively

“…This could solve many recent environmentally‐related challenges and will resolve issues concerning their sustainability 2,3,4 . With additional problems surrounding climate change on the global scale, and exhaustion of oil reserves rising, the need for several environmentally friendly and sustainable options compared with current practices continues to gain maximum focus and attention 5 . For instance, in Europe, yearly, research has shown that 20% of the 5.2 million tonnes of lubricant used is discharged into the ecosystem, and 1 kg of said mineral oil has the potency to contaminate large and significant volumes of water 6 .…”

Summary The growing concern and limitations for existing lubricants have driven the need for biolubricants, extensively proposed as the most suitable and sustainable lubricating oils. Biolubricants are generally synthesized from various bio‐based sources, including vegetable oils, microbially derived oils, waste cooking oil, etc. They are promising commodities and advantageous to mineral‐based analogues due to their exceptional properties like their lubricity, biodegradability, reduced toxicity, and reduced volatility. Yet, their utilization as lubricants is constrained due to their relatively poor cold‐flow and thermo‐oxidative stability uncertainties even after being chemically modified. Hence, many chemical modification pathways have been reported to overcome this limitation, with the most exploited approaches being esterification and transesterification. This modification pathway enhanced the thermo‐oxidative stability and the cold‐flow properties of these bio‐based oils, increased the yield, and enhanced the quality of the lubricants. With this in mind, this paper reviews up‐to‐date works conducted in this area and critically report the advancement in esterification and transesterification production of biolubricants. The study further reviews the latest published literature, current updates, and future perspectives related to the synthesis of biolubricants. Also, the review highlights the significant factors that govern the entire reaction process, selection criteria of renewable feedstocks, and the tribological performance of biolubricants.

Biolubricants derived from vegetable oils are environmentally compatible products due to their low toxicity and good biodegradability. Synthetic esters based on polyols and fatty acids possess suitable properties for lubricant applications, even at extreme temperatures. The current work investigates the oligomerization of fatty acid esters into biolubricant. The jatropha oil was esterified using recinoloeic acid and isobutyric acid over activated carbon from kaolin as a catalyst to produce biolubricant. Also, the carbon was prepared from kaolin through impregnation and activated with copper nitrate solution. The generated activated carbon was characterized using FTIR and XRF. The biolubricant (triesters) were produced via oligomeric fatty acid esters with recinoloeic acid under reflux at different reaction conditions and characterized using FTIR and GC-MS. Optimization of process parameters for oligomerization of jatropha oil with response surface based on Box-Beinkhen design. The process variables gave 90 min, 60oC and 1%, values corresponding to reaction time, reaction temperature and catalyst concentration as the optimal condition. A validation experiment was conducted to compare the optimal predicted value (93.07%) and experimental validated value (81.19%). The physicochemical properties of the jatropha oil and biolubricant produced were analyzed using ASTM methods. The quality parameters like kinematic viscosity, pour point, flash point viscosity index and blends of oil with that of commercial mineral oil were all in conformity with ASTM standard for biolubricant. The formulated oils also show the ability to significantly improve the kinematic viscosity, cold flow properties and possible potential as the replacement for the mineral-based lubricating oil
