Heat energy, value INDEX

Adiabatic temperature rise values were obtained in this study as a index of thermal hazard prediction of MEKPO. Feasible reactions at every MEKPO decomposition steps were identified from the possible reaction clusters by obtaining Gibbs free energy of reaction. And for each feasible reaction, enthalpy of reaction, heat capacity values and adiabatic temperature rise were assessed. Thermal inertia and MEKPO mixture composition ratio were considered. Adiabatic temperature rise values for each reaction condition were easily obtained, and by this, it is shown that this approach in this study can be a good methodology to get both qualitative and quantitative risk assessment result for hazardous undesirable reaction. The results were compared with the experimental and simulation data from the reference, and the errors were less than reasonable range. 

Report the yields, boiling ranges, and refractive indexes of the two esters. If available, the VPC and IR curves should be attached to the report. The identification number of the calorimeter and bomb, the individual and average values of the calorimeter heat capacity C(S) and the heats of combustion i Hc for the two esters, and the apparent strain energy for the cyclopropane ring should be reported. An estimate of the uncertainties in C(S), the two A//c values, and S should be given. 

Where R is the reflectivity and d is the thickness. Very accurate values of R and T are needed when the absorptance, (id, is small. The technique of photothermal deflection spectroscopy (PDS) overcomes this problem by measuring the heat absorbed in the film, which is proportional to ad when ad 1. A laser beam passing just above the surface is deflected by the thermal change in refractive index of a liquid in which the sample is immersed. Another sensitive measurement of ad is from the speetral dependence of the photoconductivity. The constant photocurrent method (CPM) uses a background illumination to ensure that the recombination lifetime does not depend on the photon energy and intensity of the illumination. Both techniques are capable of measuring ad down to values of about 10 and provide a very sensitive measure of the absorption coefficient of thin films.
