Recent trends in environmentally friendly lubricants

Abstract

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.

Green waxes, adhesives and lubricants

“…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).…”

Tribological Studies on AISI 1040 with Raw and Modified Versions of Pongam and Jatropha Vegetable Oils as Lubricants

“…For instance, the automotive lubricants derived from rapeseed, soy, and sunflower oils are finding good markets in European countries [4]. Also, some of the vegetable oilbased lubricants and greases are finding their opportunities in specific applications like metal forming and working, food processing industry, machine elements, marine, locomotives, and so forth [5,6]. Even though, the vegetablebased oils are finding their scope in various types of applications, it is meaningful to select oil for a particular application only after ascertaining the properties and behaviour.…”

Eco-friendly Multifunction Petroleum Additives: Preparation, Characterization and Evaluation

“…Nowadays, efforts are made to replace the ZDDP with other materials with the same properties which wouldn't be harmful to the environment. Currently, around fifty percent of the lubricants sold worldwide end up in the environment via total loss, volatility, spills or major accidents [5,6]. In view of its high ecological toxicity and low biodegradability it poses a considerable threat to the environment.…”
