Key result
Boiling pt.:
396.8 °C
Atm. press.:
97.5 kPa
Decomposition:
no
Remarks on result:
other: the boiling point was found to be 396.8 +/- 0.21 °C (95 % confidence interval), i.e. 670.0 K.

The test was carried out at 97.5 kPa atmospheric pressure. Using a linear heating rate of 0.5 °C/min, the boiling point of 4,4-Diaminodiphenylether was found to be 396.8 ± 0.21 °C (95 % confidence interval),i.e. 670.0 K.

The details are summarised in Table 1 below.

Executive summary:

The boiling point of the test item was found to be 396.8 ± 0.21 °C

Description of key information

The boiling point of the substance 4,4'-Oxydianiline was determined according to the OECD Guideline 103, under GLP conditions.

The value obtained was 396.8 ± 0.21 °C at 97.5 KPa (considered similar at 101 325 Pa)

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
396.8 °C
