Description of key information
Additional information
Based on the available data on its physical and chemical properties, heptanoic acid is a clear oily liquid with a melting point of approximately - 8°C at standard pressure, a boiling point of 223°C at standard pressure and a relative density of around 0,92 at 20°C. It is considered as a low volatility substance with a vapor pressure of 1,349 Pa at 20°C and 2,201 Pa at 25°C. It has a viscosity of 3.40 mPa.s at 30° C.
It is considered as soluble in water based on a water solubility between 1955 mg/L and 5316 mg/L, and to have a low potential for bioaccumulation based on a predicted logKow value of 2,54. It pKa of 4,75 indicates that heptanoic acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process.
Besides, heptanoic acid has been shown to be non-flammable based on its flash point of 117°C and it has an auto-ignition temperature of 275°C.
Based on its chemical structure, heptanoic acid is not expected to be explosive nor to have oxidising properties.
