Mineral oils are made by refining crude oils with physical operations. On the other hand, synthetic oils are products made by combining low molecular weight components from mineral oil or natural oils and fats via various chemical processes.Those are classified into several categories such as synthetic hydrocarbons (α-olefin oligomer, alkylbenzene, etc.), esters (diester, polyol lester, phosphate, silicate, etc.), ethers (polyalkyleneglycol, polyphenylether) and others (silicone, fluorinated compounds, etc.). Some synthetic fluids show better properties in which mineral oils are poor ; for examples, in viscosity-temperature relations, low tempreature fluidities, high temperature stabilities, fire resistances, etc.Recently, these synthetic oils are getting more important in connection with energy conservation or development of high performance machines. They are applied mainly to aircraft gas turbine oils, automotive engine oils, hydraulic oils, compressor oils and gear oils.In this review, synthetic lubricating oils are introduced for research chemists and chemical engineers of organic syntheses.
