Additional information

Remarkable physical-chemical properties of dioctylfumarate:

- The expected melting/freezing temperature of dioctylfumarate is < -20 °C.

- Dioctylfumarate decomposed before boiling at about 270 °C. The decomposed test substance boiled from 390 °C on. The calculated boiling temperature is 359.6 °C.

- The relative density is 0.942 at 20 °C

- The median particle was not determined because the test substance is a liquid.

- The vapour pressure of dioctylfumarate is 2.92 E-4 Pa at 20 °C and 6.25 E-4 Pa at 25 °C.

- The calculated partition coefficient log Pow between n-octanol and water is 7.9.

- The water solubility is 1.19 mg/L at 20 °C.

- The surface tension of the test substance was not determined because no surface activity is expected in that molecule.

- Dioctylfumarate has no dangerous physical-chemical properties.
