Thermal-oxidation mechanism of dioctyl adipate base oil

Electrical and Thermal investigation of Transformer Oil base Nanofluids

Transformer oil is one of the most important materials which are used in electrical and transformer industrial. The main function is protection and insulation of transformer core components, as well as heat transfer from its core to environment. Improving the performance of this material has been one of the researchers' concerns. The effect of different nanoparticle on the electrical breakdown ...

The Mechanism of Quench Oil Oxidation

The life of quench oil is dependant upon its thermal stability. The thermal stability is a function of the quality of the base oil, the antioxidant package used, and the presence of heat and catalysts. In this paper, the mechanism of quench oil degradation and the function of antioxidants will be explained. An example of oxidation testing to determine the role of the base oil and antioxidants i...

Thermal Oxidation Mechanism of Silicon Carbide

Application of artificial neural network for yield prediction of lipase-catalyzed synthesis of dioctyl adipate.

In this study, an artificial neural network (ANN) trained by backpropagation algorithm, Levenberg-Marquadart, was applied to predict the yield of enzymatic synthesis of dioctyl adipate. Immobilized Candida antarctica lipase B was used as a biocatalyst for the reaction. Temperature, time, amount of enzyme, and substrate molar ratio were the four input variables. After evaluating various ANN conf...

The Gas Phase Oxidation of Acetaldehyde Reaction Mechanism and Kinetics

The mechanism of the low temperature oxidation of gaseous acetaldehyde was investigated in the temperature range of 1 50-400?°C. The minor, intermediate and major products were identified and measured quantitatively by sampling directly into the ionization chamber of an MS10-C2 mass spectrometer from the reactor. The formation of H2O, CO, CO2, HCOOH, H2, HCHO, CH3COOH and CH3OH as the major pro...
