Combustion determining

Two now classical papers 61MI40400, 62JCS2927) contain almost all the experimental thermochemical data on pyrazole and indazole. Heats of combustion determined by Zimmerman (61MI40400) have been used by Dewar to calculate the heats of atomization (Table 25) (69JA796). Quantum mechanical calculations, carried out by Dewar (69JA796) or Olivella 81JHC1189), gave accurate empirical values.

By analysis and by measurement, we can determine H2 — H and express it in terms of values at 25 °C and 1 atm. Since Q is large for combustion reactions, these pressure corrections usually have a small effect on the accuracy of the heat of combustion determined in this way. 

Heating value. The heat of combustion determination may be waived at the option of the Inspector if the aniline-gravity product of the fuel is not less than the numerical values specified in Table I. The aniline-gravity product... 

Calorimetric studies were undertaken to determine whether the acetylenic linkage had remained intact during the polymerization. If the linkage were affected, heats of combustion determined experimentally should agree with the theoretical values calculated for acetylenic polymers. The heats of combustion of the acetylenic polymers were measured in a... 

A mole of hydrocarbon formed eight moles of CO2 and eight moles of H2O upon combustion. Determine the molecular formula of the hydrocarbon and give the balanced combustion reaction. 

Hence, it becomes clear that differing fractions of mineral compounds lead to different weight change effects. As, for example, the temperature, heating rate, and time of combustion determine the extent of mineral matter reactions, it is essential to stricdy follow the standard procedures enabling reproducibility [10]. 

For biomass, the enthalpy of hydration is about 0.05-0.10 J g, i.e. about 1.3-2.8 kJ C-mol , proving that the enthalpy of combustion determined for dry biomass can be used without further correction to calculate the enthalpy balance for wet biomass.
