“…Lubricants, extensively used in industry and in our day-to-day life, are compounds which are mainly obtained from mineral oils [1]. The growing concern for environmental protection has prompted the search for new and more environmentally friendly products with good lubricity characteristics [2]. In this context, lubricants derived from bio-based sources, known as biolubricants, have emerged as promising alternatives poised to supplant traditional mineral oils derived from petroleum [3].…”

“…In this context, lubricants derived from bio-based sources, known as biolubricants, have emerged as promising alternatives poised to supplant traditional mineral oils derived from petroleum [3]. Among the advantages of biolubricants, their relatively high viscosity indexes, high lubricity, lower coefficient of friction, biodegradability, and nontoxicity stand out [2][3][4][5].…”

Background: Biolubricants represent a category of lubricating substances derived from sustainable sources such as vegetable oils, animal fats, and other bio-based materials. They are considered more environmentally friendly than mineral-based lubricants because they are biodegradable and nontoxic. Biolubricants derived from vegetable oils or animal fats were used as first-generation biolubricants. They have limited performance at extreme temperatures, both high and low, as well as low oxidative stability. Substitution of the double bonds by branching improves the performance and stability of the resulting second-generation biolubricants. Methods: In the past, the production of these compounds has relied on the chemical pathway. This method involves elevated temperatures and inorganic catalysts, leading to the necessity of additional purification steps, which decreases environmental sustainability and energy efficiency. A more environmentally friendly alternative, the enzymatic route, has been introduced, in accordance with the principles of “Green Chemistry”. Results: In this paper, the esterification of 2-methylhexanoic acid with 2-octyl-1-dodecanol and its optimization were developed for the first time. The synthesis was conducted within a jacketed batch reactor connected to a thermostatic bath in a solvent-free reaction medium and using Lipozyme® 435 as biocatalyst. Conclusions: The high viscosity index value of this new hyperbranched ester (>200, ASTM D2270) suggests that it may be an excellent biolubricant to be used under extreme temperature conditions. Regarding sustainability, the main green metrics calculated point to an environmentally friendly process.

Polyols are widely synthesized from fossil sources and applied in multiple sectors of the industry as raw material for polyurethane production and also as lubricants. Although the preparation method normally used is efficient and practical, it is necessary to develop environmentally friendly synthesis route that reduce pollution. This study focuses on an alternative synthetic route for the synthesis of polyols using only raw materials from renewable sources. Polyols were successfully obtained by modifying castor oil and epoxidized soybean oil through transesterification, transamidation and oxirane ring opening. The polyols were then characterized by Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (1H and 13C‐NMR), acidity index (AI), thermogravimetry (TGA), differential scanning calorimetry (DSC), size exclusion chromatography (SEC), dynamic viscosity and exploratory scanning of ecotoxicological parameters using Artemia salina. The results highlight the promising potential of transamidated castor oil (TACO) polyol in the field of biolubricants, attributed to its high viscosity index, oxidative stability and, ecofriendly behavior.
