EXPERIMENTAL Thermogravimetric analyses were conducted on samples of free fatty acid. The samples onwisconsin.com were heated from 25° C to 300° C using various heating rates. Sample weight was recorded as a function of temperature for each test, and subsequently plotted as percent of original weight versus furnace temperature. A reaction that leads to weight loss (such as evaporation) will give rise to a step on the TG curve. Each set onwisconsin.com of TG test results were processed using a thermal analysis kinetic evaluation program to obtain routine Arrhenius equation kinetic parameters onwisconsin.com (activation energy and reaction rate). From the kinetic data, calculations were performed in order to estimate the half-time of the evaporation rate (i.e., the amount of time that would be required for one half of the fatty acid sample mass to evaporate) for a number of ambient temperatures. Reaction rate and half-time data for the evaporation of the three fatty acids, calculated at four reference temperatures, are listed in Table 1.
