DOWNLOAD EBOOKIt is desirable to know the degree of the thermal decomposition of motor oils, at elevated temperatures in both neutral and oxidizing media. To test for this property, the authors used thermogravimetric analysis. When an oil sample is heated in a neutral medium some of its components evaporate. When the sample is heated in air, evaporation occurs at first, but soon thereafter oxidation and decomposition take place as well. The correlation between the loss of mass (evaporation) and the temperature is indicative of the oil's fractional composition in the first case and of its resistance to thermal decomposition in the second case.
