Any other information on results incl. tables

Functional control

The test system was controlled with double distilled water at an atmospheric pressure of 1022 hPa. The normal boiling was determined to be 99.9 °C which is within±0.2 K (°C) from the literature value of 100.0 °C.

Boiling Point

The results of two independent measurements within±2 K are given in the table. The boiling temperatures were converted to the boiling point under normal pressure by the apparatus automatically.

 The test item was heated up to 175 °C and the behaviour of the test item was observed over a period of 1 h at constant temperature. Neither discoloration nor other signs for decomposition could be observed.

Applicant's summary and conclusion

Conclusions:

The boiling point of the test item F-DIOX acid was determined to be 442.2 K (169.0 °C) under normal pressure (1013 hPa).

Executive summary:

The boiling point of the test item (batch number: 240/13) was determined according to OECD-Guideline No. 103 for Testing of Chemicals and Council Regulation (EC) No. 440/2008 Method A.2 on 2011-01-24 at Dr. U.Noack-Laboratorien, 31157 Sarstedt, Germany.

 

The determination of the boiling point was performer with a capillary tube in a metal block apparatus at an atmospheric pressure of 1020 hPa.

 

The normal boiling point (under normal pressure of 1013 hPa) was determined to be 442.2 K (169.0 °C).
