Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

2.24 E-15 mm Hg (25 °C)

2.99 E-13 Pa (25 °C)

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
25 °C

Additional information

The vapour pressure value of the AP 1300 S has been estimated by means two different tools which predicted very similar values:

MPBWIN v1.43 (September 2010) by the modified Grain method

Vapoure pressure (mm Hg, 25 °C): 2.24 e-15

Vapoure pressure (Pa, 25 °C): 2.99 e-13

ACD/Labs Percepta Platform - Boiling Point/Vapor Pressure Module

Vapoure pressure (mm Hg, 25 °C): 0.0 ± 2.1

The vapour pressure value reported for the Similar Substance 01 in the ECHA website is > 0.027 < 0.031 Pa, at 20 °C

In order to complete the assessment the whole data set has been considered and the value predicted by means of MPBWIN v1.43 (September 2010) by the modified Grain method has been used as Key value for the chemical safety assessment.
