Mesitylene

Vapour pressure

Link to relevant study record(s)

Reference

Endpoint:

vapour pressure

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: Non-GLP; non-guideline; Information from published handbook, data compendium, review article or other reference text; acceptable with restrictions.

Deviations:

not specified

Principles of method if other than guideline:

The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to the Handbook of Vapor Pressures and Heats of Vapourization 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.

GLP compliance:

not specified

Type of method:

other: No data

Key result

Temp.:

25 °C

Vapour pressure:

3.2 hPa

Remarks on result:

other: Extrapolated value using Antoine Equation. The Antonine coefficients were determined in the temperature range 48.9⁰C to 193⁰C.

Transition / decomposition:

no

Conclusions:

The vapour pressure of mesitylene (1,3,5-trimethylbenzene) was determined to be 3.2 hPa at 25 ˚C.

Executive summary:

This information is taken from a reliable peer reviewed handbook and is considered reliable and suitable for use as the key study for this endpoint. The endpoint was determined by extrapolation using the Antonine equation. The Antonine coefficients were determined in the temperature range 48.9 °C to 193 °C. The vapour pressure of mesitylene (1,3,5-trimethylbenzene) was determined to be 3.2 hPa at 25 °C.

Description of key information

The endpoint was determined by extrapolation using the Antonine equation. The Antonine coefficients were determined in the temperature range 48.9 °C to 193 °C. The vapour pressure of mesitylene (1,3,5-trimethylbenzene) was determined to be 3.2 hPa at 25 °C.

Key value for chemical safety assessment

Vapour pressure:

320 Pa

at the temperature of:

298.2 K

Additional information

The handbook by Zwolinski (1971) is peer-reviewed and is considered reliable and suitable for use as a key study. The supporting study (CRC Handbook 2008) is also a peer reviewed handbook and reports a vapour pressure of 1 kPa at 43.7 °C.
