The heat of combustion is the amount of heat released when one mole of a substance undergoes combustion according to the general reaction equation:
CxHyOz + 0.25(4x+y-2z) O2 (g) → x CO2 (g) + 0.5y H2O (ℓ)

ΔHcomb° (ℓ): -1620.04817399618 kcal = -6778.33 kJ
ΔHcomb° (g): -1632.33306883365 kcal = -6829.73 kJ

Safety Information

NFPA 704 Ratings:
Health: 1 - Exposure would cause irritation with only minor residual injury.
Flammability: 2 - Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur. Flash point between 38°C (100°F) and 93°C (200°F).
Reactivity: 0 - Normally stable, even under fire exposure conditions, and is not reactive with water.
