“…These problems are attributed to high viscosity, low volatility and polyunsaturated character of neat vegetable oils, which could be substantially reduced by conducting chemical modifications to the carboxyl group in TAG molecules of vegetable oils. Transesterification (Anand et al 1998;Bírová et al 2002;Hörner 2006) is one of the common ways to chemically break the molecules of the raw vegetable oils into their methyl or ethyl esters with glycerol as a by-product. Transesterification reactions of the partially hydrogenated and cyclized ester vegetable oils are important because these reactions yield monoesters of vegetable oils with better thermal stability and lower freezing points than the vegetable oils as such (Uosukainen et al 1998;Bokade & Yadav 2007).…”

General characteristics of waxes, adhesives and lubricants as well as the recent fundamental investigations on their physical and mechanical behaviour are introduced. The current R&D status for new type/generation of waxes, adhesives and lubricants from natural products is reviewed, with an emphasis on their tribological applications. In particular, some crucial issues and challenges relating to technological improvement and materials development are discussed. Based on the current predicted shortage of energy resources and environmental concerns, prospective research on the development of green waxes, adhesives and lubricants is suggested.

“…Although different regions have adopted different criteria and limits for toxicity and biodegradability depending upon their respective sociopolitical environments, an appraisal of these criteria suggests that the choice of rapidly biodegradable non-toxic base fluids boils down to vegetable oils, vegetable oil derived esters, other synthetic esters, polyalkylene glycols and polyalkylene glycol ethers. [4,5,[18][19][20] Vegetable oils, especially the 'high oleic' variety, have relatively poor oxidation and poor hydrolytic stability as compared to highly refined High Viscosity Index (HVI) petroleum based oils now used in various lubricant applications, although their thermal stability and corrosion protection properties are comparable to each other. The oxidation stability of esters, on the other hand, varies with the type of ester.…”

“…In India [18][19][20] large quantities of low cost vegetable oils of forest and wasteland origin are available which can be converted easily by such means as hydrogenation, transesterification, acetylation and alkylation into lubricant base fluids of moderate to high thermooxidative stability, low temperature flow properties, superior viscosity-temperature and lubricity characteristics. These products are non-toxic and 90-100% biodegradable.…”

A critical appraisal is made of the applications of vegetable oils, the fatty esters complex and synthetic esters as rapidly biodegradable and non-toxic lubricants and fuels in the developed countries of America, Europe and Asia.The criteria employed for assessing the toxicity and biodegradability of the various fluids and limits set by various state and regional organizations are reviewed. The properties of vegetable oils, fatty esters, chemically modified esters and synthetic esters relevant for performance as lubricants in various applications such as hydraulic oils, refrigeration oils, chainsaw lubricants, metalworking fluids, engine oils, two-stroke oils, mould release lubricants, greases, gear and transmission oils vis-à-vis conventional mineral oils and greases for corresponding applications are compared. The advantages, such as high lubricity, viscosity-temperature relationship, low lubricant consumption, energy efficiency combined with public health, safety and environmental contamination, more than offset the disadvantages of initial costs in most of these applications.It has been suggested that modified and stabilized oils of wasteland and forest origin and other non-edible oils and their chemically modified derivatives can be produced at relatively cheaper cost than similar oils marketed in the developed world and can be introduced in India with immense environmental and performance benefits, particularly in applications involving high environmental contamination safety and public health.When blended with highly refined diesel fuels, methyl esters can work as highly efficient environment-friendly fuels particularly for applications in passenger transport, light commercial vehicles and generators.

Many of'the lubricants used in the world today cause environmental pollution through total-loss applications, spillage, evaporation, and in other ways. To reduce this environmental damage, new lubricants that are rapidly biodegradable and ecologically non-toxic have started to be developed and marketed. This paper discusses the introduction of environmentally fr-iendly lubricants and their constituents, with particular emphasis on their environmental benefits, applications, the limits to their use, their technical peiformance characteristics, and relative cost aspects; many of these lubricants are based on segetable oils and esters. Comparisons are also made in the paper with conventional mineral-oil based materials.Keywords lubricants, envirorimental pollution, biodegradability, vegetable oils, ester-based litbricaiits J.
