“…Trimethylolpropane (TMP) fatty esters are considered as biolubricants (Panchal et al, 2017;Syahir et al, 2017;Zainal et al, 2018) with improved stability properties, in comparison with the analogous triglycerides (Sripada et al, 2013). TMP triesters have been prepared by esterification of TMP with free fatty acids or by transesterification of fatty acid methyl esters (FAMEs).…”

The fatty acid ethyl esters mixture, a fish oil residue obtained after the extraction of omega-3 polyunsaturated fatty esters, has been converted into mixtures of mono-, di-, and triesters of trimethylolpropane by transesterification at 100-140ºC under vacuum with sodium ethoxide as catalyst. This method has shown to be more efficient than the enzymatic transesterification using commercially available lipases. The crude reaction mixture (84% conversion of ethyl esters), enriched in trimethylolpropane triesters (96% selectivity) was characterized and its properties compared with those of the starting ethyl esters mixture and the trimethylolpropane esters obtained from vegetal sources.

“…It is noteworthy that vegetable oils enjoy some superior physicochemical properties compared with mineral lubricants, including higher viscosity indices and better lubricity, leading to lower friction losses and better fuel economy, and higher flash points, yielding greater safety for transportation and storage purposes and lower evaporation rates leading to low emissions into the atmosphere. However, lower oxidation stability and a higher pour point are the main drawbacks for vegetable oils, which limit their direct use as lubricants in lubrication systems . Some researchers have recently reviewed different methods that are used to amalgamate the physicochemical properties and mitigate the deficiencies of vegetable oils .…”

The reduction in crude oil resources, its volatile prices, and the irreparable environmental pollution caused by their production and consumption have led to worrying global challenges. At the same time, ever‐increasing population growth and growing industrialization have resulted in an increasing demand for petroleum‐based crude oil products, including lubricants. In this respect, the proper management of biomass to produce higher value‐added products such as biolubricants is very important. Iran, with a population of more than 80 million, is the fourth largest producer of crude oil and one of the largest lubricant producers in the region, but the development of clean bio‐based lubricants has always been neglected there, mostly due to the abundance of petroleum. The present study, reviewing the status of Iran's lubricant industry and its technical and environmental challenges, investigates the potential use of conventional edible oils and introduces novel drought‐resistant native edible oil sources, for the production of biolubricants. It is believed that this case study could be of assistance to researchers and specialists in developing countries, enabling them to take action to confront the challenges ahead by relying on sustainable development based on renewable and environmentally friendly products. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd

Three kinds of crop leaf-surface waxes were extracted from wheat, corn and broomcorn leaves, respectively. The crop leaf-surface waxes as lubricant additives were added to synthetic ester and the friction and wear properties of prepared lubricants for steel-aluminum and steel-copper friction pair were investigated in detail. The scanning electron microscopy (SEM) and secondary ion mass spectrometry (SIMS) were employed to explore the friction mechanisms. The results show that crop leaf-surface waxes could successfully reduce the friction and wear of steel-aluminum and steel-copper sliding friction pairs as compared with pure synthetic ester. For example, when the concentration of wheat leaf-surface wax as additive was 2%, the COFs was decreased by 58%; the four additives can be ranked by the anti-wear capability as follows: Corn > Wheat > Glycerol >Broomcorn to steel-aluminum sliding friction pairs. The SIMS spectra of positive and negative ions on the worn surfaces have reduced the exposure of Al and increased short chain ions counts. The good friction reduction and antiwear abilities are attributed to the adsorption or reaction films formed by leafsurface wax on worn surface.
