Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
Principles of method if other than guideline:
The introduction to the Handbook of Vapor Pressures and Heats of Vaporization of Hydrocarbons and Related Compounds states that data included has been collected, calculated, critically selected and compiled. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data.

This handbook reports vapour pressures for toluene from 45°F to 280°F together with the Antoine equation constants to allow vapour pressures at other temperatures to be calculated. For toluene the constants are A = 5.24, B = 2420.64, C = 363.07 and t = temperature in Fahrenheit. The Antoine equation is log P = A - (B/(C+t).

Conclusions:
The reported vapour pressure of toluene is 0.448 PSI (3088.9Pa) at 70°F (21.1°C) and 0.599 PSI (4130.0Pa) at 80°F (26.6°C).
Executive summary:

The reported vapour pressure of toluene is 0.448 PSI (3088.9Pa) at 70°F (21.1°C) and 0.599 PSI (4130.0Pa) at 80°F (26.6°C).
