Results:

 No.  Sample mass [mg]  Boiling point [° C]  Corrected boiling point [° C]
 1  19.8 360.9   360.7
 2  12.4  361.4  361.2
 Mean value      361.0
Conclusions:
Boiling point of 1,8-naphthylendiamine was determined to be 361 °C via differential scanning calorimetry.
Executive summary:

The boiling point was determined with the DSC-method described in ASTM E 472 -86 and DIN 51007:1994. The sample was placed in a crucible from aluminium closed with a cap. 1,8-naphthylenediamine and a reference substance were heated at a linear rate of 10 K/min from 30 °C up to 400 °C. The boiling point of 1,8 -naphthylendiamine was determined to be 361 °C (mean value).

Description of key information

The boiling point to test item 1,8-naphthylendiamine was determined to be 361 °C (mean value) via differential scanning calorimetry. The test procedure was carried out according to EC No. 440/2008 A.2.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
361 °C
