“…Most of above listed difficulties can be avoided by the use of heterogeneous catalyst. In literature, we can be find many of specific and effective catalysts used in the synthesis of polyol fatty acid esters, in particular acidic Zr, Al, Si mixed oxides, superacids, and heteropolyacids . Heterogeneous catalysts are characterised by several advantages.…”

In this paper, we present the study on the synthesis, physico‐chemical, and tribological characterisation of selected plant‐derived fatty acids esters of higher polyols. We described here more effective method synthesis of desired esters with high yields and high selectivities. In our novel and improved synthesis protocol, we applied homogeneous Sn catalysts. Physico‐chemical characterisation and lubricating properties of synthesised esters have been determined and discussed. Our results showed that the synthesised esters are characterised by excellent viscosity, good low temperature, and lubrication properties. High thermal resistance is the main benefit of synthesised esters. For fatty acid esters of trimethylolpropane dimer, onset temperatures are around 400°C and decomposition temperatures above 460°C, which makes these esters applicable in higher temperature.

“…The authors described this method as “zero waste”, but the use of heterogeneous catalyst before next re-use requires washing with harmful acetone. Itsikson, in turn, studied the esterification reaction of pentaerythritol and oleic acid with the use of tributyl phosphate, tributyl phosphite, sodium sulfate and activated carbon impregnated with H 2 SO 4 as a catalyst [ 20 ]. The reaction was carried out with 10 % molar excess of oleic acid, which was subsequently removed by distillation under high vacuum.…”

Studies on the synthesis of esters of natural origin fatty acids (oleic acid) and a branched synthetic isostearic acid derived from oleic acid with commercially available selected higher polyols in the presence of homogeneous metallic catalysts have been carried out. The effects of the synthesis temperature, molar ratio and the catalysts amount have also been studied. It was shown that higher fatty acid conversion and selectivity to tri- and tetraesters were obtained for organotin catalyst Fascat 2003, which was used as the esterification catalyst. Anti-wear test confirmed good tribological properties of the obtained esters.

Background:Pentaerythritol (2,2-bis (hydroxymethyl) propane-1,3-diol) as white crystalline odorless solid has been synthesized in 1891. Pentaerythritol is multifaceted species in many compounds, which are wildly utilized in medicine and industry. Also, multicomponent reactions (MCRs) play a crucial role in organic and medicinal chemistry. Hence, in these reactions, pentaerythritol is a versatile substrate for the synthesis of many polyfunctionalized products, because of the presence of the neopentane core and one hydroxyl group in each of the four terminal carbons. </P><P> Objective: The review describes pentaerythritol multicomponent reactions in the presence of different solvents in the reaction medium to produce various compounds including pentaerythritols. This review covers the literature relevant up to 2018.Conclusion:It is obvious from the provided review that a great deal of research has been done in this field, utilizing various mediums (solvent-free conditions, aqueous media, and organic solvents) for the synthesis of the products of containing pentaerythritols. This classification is based on the importance of economic and environmental friendly reactions. Due to the whole aforesaid reports, some reactions required heat for their progress, and some others were accompanied by microwave or ultrasonic waves.
