Reference
Endpoint:
vapour pressure
Type of information:
calculation (if not (Q)SAR)
Remarks:
estimated by calculation
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Accepted calculation method.
Principles of method if other than guideline:
MPBPWIN estimates vapour pressure by three separate methods: (1) the Antoine method, (2) the modified Grain method, and (3) the Mackay method. All three use the normal boiling point to estimate VP.
GLP compliance:
no
Type of method:
other: Calculated with MPBPWIN v1.42
Temp.:
25 °C
Vapour pressure:
0 hPa
Remarks on result:
other: Modified Grain Method

The vapour pressure was calculated on the basis of a calculated boiling point of 381 °C.

Conclusions:
The estimated value for vapour pressure of N-(1,4-dimethylpentyl)-N'-phenylbenzene-1,4-diamine is 0.00000281 hPa at 25°C. (Currenta, 2009)
Executive summary:

The estimated value for vapour pressure of N-(1,4-dimethylpentyl)-N'-phenylbenzene-1,4-diamine is 0.00000281 hPa at 25 °C.

Description of key information
