Lubricating oils Usage And Synthesis
DescriptionThe term ‘lubricating oil’ refers to a wide range of products that are characterized by hundreds of base chemicals and additives. Lubricating oils may be either mineral-based or synthetic. The mineral-based are more widely used than the synthetic oils. This article focuses on petroleum-based lubricating oils, which are composed of 80–90% of petroleum hydrocarbon distillates and 10–20% of additives. Additives are necessary to impart specific properties to the oil for specific applications and include among others ‘extreme pressure additives,’ antiwear additives, corrosion inhibitors, oxidation inhibitors, viscosity index improvers, or demulsifiers.
Lubricating oils are a complex combination of hydrocarbons obtained from solvent extraction and dewaxing processes. It consists predominantly of saturated hydrocarbons having carbon numbers in the range C15 through C50, with the heavier distillates having higher percentages of the higher carbon number compounds. The mineral-based oils are produced from heavy-end crude oil distillates and they contain hundreds to thousands of hydrocarbon compounds, including a substantial fraction of nitrogen- and sulfur-containing compounds. The hydrocarbons are mainly mixtures of straight and branched chain hydrocarbons (alkanes), cycloalkanes, and aromatic hydrocarbons. PAHs (polycyclic aromatic hydrocarbons), alkyl PAHs, and metals are important components of motor oils and crankcase oils. Lubricating oil composition changes under the use conditions of heat and friction and, if appropriate, exposure to exhaust gases of internal combustion engines. Used lubricating oils or crankcase oils generally have higher concentrations of PAHs than unused oils and they are considered to be more toxic. Used lubricating oils are not specifically addressed in this article.
The petroleum hydrocarbon distillate generally consists of paraffinic or naphthenic compounds. The exact composition of mineral-based lubricating oil as petroleum products varies depending upon (1) the source of the crude oil (crude oil is derived from underground reservoirs which vary greatly in their chemical composition) and (2) the refining practices used to produce the product. All the lubricating oils listed in Table 1 have been classified in Europe on the basis of the Global Harmonized System (GHS) as carcinogen category 1B (known or presumed to have carcinogenic potential for humans based primarily on animal evidence) with the hazard statement of H350 may cause cancer.
UsesLubricating oils are used for lubrication of various internal combustion engines. The uses of mineral oils include applications such as engine oils, automotive and industrial gear oils, transmission fluids, hydraulic fluids, circulating and hydraulic oils, bearing oils, and machine oils. Other uses are as machinetool oils, compressor and refrigerator oils, textile machine oils, air tool oils, steam engine oils, and metalworking oils.
Mineral oils have also medicinal and food uses; they are used as ingredients in various pharmaceutical and cosmetic preparations and as a vehicle for drugs, and in fungicides, chemical and plastics industries (e.g., processing medium, extenders, plasticizers), and animal feed products. Two chemical classes (paraffin waxes, CAS 8002-74-2 and petrolatum, CAS 8009-03-8) are considered generally recognized as safe food ingredients by the Food and Drug Administration (FDA).
usesLubricating oils are based on aliphatic hydrocarbon molecules containing 17 or more carbon atoms. The wide array of lubricating oil mixtures are used to reduce the friction and heat produced when mechanical parts come into contact with one another. Similar to cutting oils, there are two major classifications: (1) mineral, which are made from refined petroleum, and (2) synthetic, which are made from other oil sources. The exact composition of lubricating oils varies, as lubricating oils are complex mixtures that contain small amounts of aromatic and polycyclic substances and a broad variety of dissimilar materials known collectively as additives. Additives serve a variety of functions, including inhibiting corrosion or oxidation, preserving integrity of the oil film, altering the viscosity of the mixture, suppressing bacterial growth within the mixture, or acting as a detergent. The presence of the additives determines the toxicity and possible adverse health outcomes of lubricating oils.
Flammability and ExplosibilityNon flammable
Environmental FateThe physical–chemical properties of mineral oils depend on their composition in terms of carbon number distribution, and this is defined by the source of crude oil. It shows the physical–chemical properties of both lubricating oil in general and the most relevant substances present in lubricating oils.
Generally, they are viscous fluids with brown to black color. The higher the carbon number, the higher the viscosity of the fluid. They are insoluble in water and alcohol, but are soluble in benzene, chloroform, ether, carbon disulphide, and petroleum ether. Lubricating oils are photodegraded by sunlight at 1 000 000 molecule m-3.
Toxicity evaluationThe mechanism of lubricating oil toxicity is mediated through its irritant effects, which after sufficient exposure duration and concentration result in tissue hyperplasia. Chronic hyperplasia leads to subsequent loss of tissue integrity and damage, and cancer in some animal models.
