asphaltenes, are reacting, and that possibly in doing so some are acting as oxidation inhibitors for the paraffinic hydrocarbons present. Such mildly refined oils are not much improved by the addition of antioxidants. More severe refining or hydrogenation produces a more highly paraffinic oil which absorbs oxygen more readily but without producing such harmful oxidation products. More important, however, the oxidation resistance of such highly refined base oils is very considerably improved by the addition of suitable oxidation inhibitors. Most modern petroleum-base oils are highly refined in order to give consistent products with a wide operating-temperature range. Antioxidants are therefore an important part of the formulation of almost all modern mineral-oil lubricants. The commonly used antioxidants are amines, hindered phenols, organic phosphites, and organometallic compounds. One particularly important additive is zinc diethyl dithiophosphate, which is a very effective antioxidant and also has useful boundary lubrication and corrosion-inhibition properties. If no oxygen is present, lubricants can be used at much higher temperatures without breaking down. In other words, their thermal stability is greater than their oxidative stability. This effect can be seen for mineral oils in Table 20.3. To prevent contact of oxygen with the oil, the system must be sealed against the entry of air or purged with an inert gas such as nitrogen. Some critical hydraulic systems, such as those in high-speed aircraft, are operated in this way. In high-vacuum systems such as spacecraft or electron microscopes, there is no oxygen contact. But in high vacuum an increase in temperature tends to vaporize the

oil, so that high thermal stability is of little or no value. It follows that oxidative stability is usually much more important than thermal stability. Compatibility of lubricating oils with other materials in the system is complex, and Table 20.4 lists some of the possible problems and solutions. Compatibility problems with synthetic lubricants are even more complicated; these are considered further in the next section.

So far most of the information in this chapter has been related to mineral oils. For almost 150 years the availability, good performance, variety, and cheapness of mineral oils have made them the first choice for most applications. They still represent over 90 percent of total lubricant use, but many other liquids are used successfully as lubricants and can provide special features which make them the best choice in particular situations. Table 20.5 shows the most important types of lubricating oil and their advantages and disadvantages as compared with mineral oils. The natural oils comprise a wide variety of compounds of vegetable or animal origin, consisting mainly of organic esters. They all have better low-friction and boundary lubrication properties than mineral oils, but lower thermal and oxidative stability. Before mineral oils became generally available, natural oils and fats were the most common lubricants, and several are still widely used because their properties make them particularly suitable for special applications, as shown in Table 20.6. The diesters were the first synthetic lubricating oils to be used in large quantities. Their higher thermal and oxidative stability made them more suitable than mineral
