Boiling point
Administrative data
Link to relevant study record(s)
Description of key information
The boiling point has been determined by two different methods:
- using the distillation method at atmospheric pressure, Method A2 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC) and
- using the Distillation of Petroleum Products at Atmospheric Pressure method, ASTM D 86 - 04b.
The overall boiling temperature range is to be quoted using the results obtained following Method ASTM D 86:
- 218 to 357°C at 101.1 kPa [key information]
- 173.7 to 344.3 °C at 101.1 kPa [supporting information; product properties data by company (result of 13 determinations/batches; study period: 06/2011 - 01/2012)]
Key value for chemical safety assessment
Additional information
Method A2 of Commission Directive 92/69/EEC
Overall boiling temperature range 76 to 304 °C at 100.96 to 101.28 kPa [the mean 50% distillation temperature was 278 ± 0.5 °C and the mean mid-90% distillation range (5 to 95% distillation) was 195 to 302 ± 0.5°C].
Discussion:
The standard Annex V method for the determination of boiling temperature using the distillation method at atmospheric pressure (ISO 918) is not appropriate for test materials of this nature.These test materials are classed as petroleum products with broad boiling temperature ranges.
The determination of boiling temperatures for petroleum products uses a specific method (IP 123 Petroleum Products - Determination of Distillation Characteristics) which is referenced in ASTM D 86, Standard Test Method for Distillation of Petroleum Products at Atmospheric Pressure.
Method ASTM D 86
The boiling temperature range of the test material was determined to be 491 to 630 K (218 to 357°C) at 101.1 kPa. This result/range was confirmed by determination of 13 different batches: 173.7 to 344.3 °C.
