• organic • carboxylic acid

Paggamit / Function

• "Adipic acid is used in large quantities for the manufacture of nylon." 1

• "Manuf[acture] artificial resins, plastics (nylon), urethan foams. Used as acidulant in baking powders instead of tartaric acid, cream of tartar, and phosphates because adipic acid is not hygroscopic. As an intermediate in lubricating oil additives." 2

termokimika

ΔHf° (s): -237.60 kcal/mol 5 = -994.12 kJ/mol
ΔHf° (ℓ): -235.51 kcal/mol 5 = -985.37 kJ/mol

ΔGf° (ℓ): -177.17 kcal/mol 7 = -741.28 kJ/mol

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° (s): -668.275 kcal = -2796.0916 kJ
ΔHcomb° (ℓ): -670.365 kcal = -2804.83616 kJ
