In a study, according to OECD 104, the vapour pressure of neodecanoic acid, iron salt has been characterised.
Measured values ranged between 1.02 and 9.57 mPa, which falls within the applicability domain of the Knudsen cell method (10-10 to1 Pa, according to the guideline). The vapour pressure of the test item was 0.00125 Pa at 20°C and 0.00183 Pa at 25°C, interpolated from the regression.
Reference
Measured values ranged between 1.02 and 9.57 mPa, which falls within the applicability domain of the Knudsen cell method (10-10 to1 Pa, according to the guideline). The vapour pressure of the test item was 0.00125 Pa at 20°C and 0.00183 Pa at 25°C, interpolated from the regression.
There was no difference between the FTIR analysis of the native test substance, the control or any of the tested material, confirming stability during testing.
