Principle of Boiling point test

The boiling point of a liquid is the temperature at which that liquid is converted to a gaseous state. It can be defined as the temperature at which the vapour pressure of the liquid becomes equal to the pressure at the surface of the liquid.

Conclusions:
The mean boiling point of 1,4-Dichloro-2-nitrobenzene (CAS No. 89-61-2) is 241.3°C at 972.0 hPa.
Executive summary:

The boiling point determination of 1,4-Dichloro-2-nitrobenzene (CAS No. 89-61-2) was done following OECD Guideline 103 and according to the method of Siwoloboff. The test was conducted in replicates and mean boiling point was determine to be 241.3°C at 972.0 hPa.

Description of key information

The boiling point determination of 1,4-Dichloro-2-nitrobenzene (CAS No. 89-61-2) was done following OECD Guideline 103 and according to the method of Siwoloboff. The test was conducted in replicates and mean boiling point was determined to be 241.3°C at 972.0 hPa.

Key value for chemical safety assessment

Additional information

The boiling point determination of 1,4-Dichloro-2-nitrobenzene (CAS No. 89-61-2) was done following OECD Guideline 103 and according to the method of Siwoloboff. The test was conducted in replicates and mean boiling point was determined to be 241.3°C at 972.0 hPa.

Determination of boiling point of chemical 1,4-dichloro-2-nitrobenzene. The boiling point of chemical 2,5-Dichloronitrobenzene is determine to be 267 deg C.

Thus based on the above both data, boiling point was ranges from 241.3 to 267°C.
