Executive summary:

According to Physical property data is provided to ChemIDplus by SRC, Inc., Vapour pressure of DBTU is about 2.38e-8 mmHg

Description of key information

Three different sources are compared:

• According to ACS calculation, vapour pressure of DBTU is about 2.03 .10-3 torr (0.266 Pa) at 25°C.
• According to Physical property data is provided to ChemIDplus by SRC, Inc., Vapour pressure of DBTU is about 2.38e-8 mmHg (3.05 .10 -5 Pa)
• According to the OECD Toolbox QSAR, VP of DBTU is about 0.00254 mmHg -- Vapor Pressure (Modified Grain Method) (EPISUITE). (0.338 Pa)

As a worst case value, VP of DBTU should be lower to 0.25 Pa at 25°C

Key value for chemical safety assessment

Vapour pressure:

0.25 Pa

at the temperature of:

25 °C
