Study on Autoxidation Kinetics of Fats by Differential Scanning Calorimetry. 1. Saturated C12−C18 Fatty Acids and Their Esters

“…Differential scanning calorimetry (DSC) have found application in the investigation of both physical phenomena (i.e., changes in crystallographic properties, melting, sublimation, and adsorption) and chemical phenomena (dehydratation, decomposition, oxidation, and reduction), and review works of Dollimore − give a wide insight into recent literature in these fields. Stability of petroleum oils under oxidative conditions characterized by DSC was described in a review concerning thermal analysis of petroleum products .…”

“…The total rate of autoxidation is determined by the rate of hydroperoxides formation (during the initial stage, eq 1), and in the early stages, when the hydrocarbon conversion and the hydroperoxides concentration are low, the decomposition of primary products is expected to be first order: Differential scanning calorimetry (DSC) have found application in the investigation of both physical phenomena (i.e., changes in crystallographic properties, melting, sublimation, and adsorption) and chemical phenomena (dehydratation, decomposition, oxidation, and reduction), and review works of Dollimore [15][16][17] give a wide insight into recent literature in these fields. Stability of petroleum oils under oxidative conditions characterized by DSC was described in a review concerning thermal analysis of petroleum products.…”

A Modified Thermogravimetric Analysis Apparatus of Improved Performance

“…Typically, the derivative TGA (DTG) peaks in MCP decomposition are not as well defined and sharp as those in the decomposition of many other salts, e.g., calcium oxalate monohydrate. − Nonetheless, in the present study, even an 85-μg sample of MCP has been used successfully. A comparison was made between the thermal decomposition of this sample and that of three other samples: a “duplicate” sample of 91 μg and two samples orders of magnitude larger, i.e., of 712 and 6390 μg.…”

“…Conventional thermogravimetric analysis (TGA) , is usually sensitive to weight changes of a sample down to about 0.1% of the total weight . Thus, for a typical 10-mg sample, mass losses below about 10 μg cannot be accurately monitored under standard TGA conditions, despite manufacturers' claims of a 0.1-μg limit of balance sensitivity.…”

A Review on Synthesis, Characterization and Applications of Cadmium Ferrite and its Doped Variants

“…TGA is a destructive technique, which is one of its key drawbacks 71 . To synthesize pure Cd ferrite samples A, B, and C, an equimolar mixture of Cd nitrate and α-Fe 2 O 3 was impregnated, dried, and then thermally treated at 900, 1100, and 1200 0 C for 3 hours.…”
