Adequacy of study:
key study
Reliability:
1 (reliable without restriction)

according to
Guideline:
OECD Guideline 104 (Vapour Pressure Curve)

Key result
Vapour pressure:
<= 0 Pa
Remarks on result:
not determinable because of methodological limitations

An experimental vapor pressure was not attempted after the EPI Suite estimates for the components were obtained because no method is recommended for vapor pressures lower than 10-5 Pascals. A list of known vapor pressure values are presented in the table below.

Vapor Pressure Estimates of Test Substance Components

Component  Vapor Pressure (Pascals)  Temperature (0C)  Source
Phenol  20, 29, 48 20 IUCLID
Benzyl Alcohol  3
Phenylene bismethylamine  1.95 25 EPI Suite estimate
Phenol + diamine  3.63 x 10-4
2 phenols + diamine  2.48 x 10-10
2 diamines + phenol  7.89 x 10-9
2 diamines + 2 phenols  1.91 x l0-13
Conclusions:
An experimental vapor pressure was not attempted after the EPI Suite estimates for the components were obtained because no method is recommended for vapor pressures lower than 10^-5 Pascals.
