For the correction Δt of the boiling point to standard atmospheric pressure (1013.3 hPa) the equation, table and graphs of H.B. Hass and R.F. Newton in ,,CRC Handbook of Chemistry and Physics, 74th ed. 1993-1994“, pages 15-16 and 15-17 were used.

Δt = [(273.15+t) (3.0057-log p)] / [Φ + 0.15(3.0057-log p)] (t in °C, p in hPa)

For the estimation of Φ the test item was classified in group 2 (hydrocarbons) according to the table of H.B Hass and R.F. Newton.

The boiling range of the test item at atmospheric pressure (1013.3 hPa) is 362 - 370 °C.

Conclusions:
The boiling range of the test item at atmospheric pressure (1013.3 hPa) is 362 - 370 °C.
Executive summary:

A study was conducted to determine the boiling point of the test item. The study was performed according to Council Directive 92/69/EEC, method A.2 and OECD Guideline No. 103 (1995). The determination of the melting point / boiling point was carried out by differential scanning calorimetry (DSC). The test item was heated up from ambient temperature to the final temperature (450 °C) at a constant heating rate (10 K/min) in a defined atmosphere (nitrogen). The quantity of heat absorbed or released was measured and recorded. The determined boiling range of the test item at atmospheric pressure (1013.3 hPa) is 362 - 370 °C.

Description of key information

The boiling range of the test item at atmospheric pressure (1013.3 hPa) is 362 - 370 °C (reference 4.3-1).

Key value for chemical safety assessment
