Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 21 Nov 2013
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM D1120-94 “Standard Test Method for Boiling Point of Engine Coolants"
- GLP compliance:
- no
- Type of method:
- dynamic method
- Key result
- Boiling pt.:
- 217.6 °C
- Atm. press.:
- 760 mm Hg
- Remarks on result:
- other: Extrapolated from pressure-temperature regression in linked vapor pressure study
- Conclusions:
- MTDID 44428 has a boiling point 217.6 °C at 760 mmHg (ASTM D1120-94).
- Executive summary:
The boiling point of MTDID 44428 was determined the dynamic test method. The normal boiling point was extrapolated from vapor pressure-temperature data reported elsewhere in this dossier. The vapor pressure study was performed in accordance with a guideline study but not GLP compliant. Therefore, the study is considered reliable with restrictions.
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- disregarded due to major methodological deficiencies
- Study period:
- 19-30 Apr 2019
- Reliability:
- 3 (not reliable)
- Rationale for reliability incl. deficiencies:
- unsuitable test system
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- method according to Siwoloboff
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source (i.e. manufacturer or supplier) and lot/batch number of test material:
41-4205-7138-6 (R-57318), CPDC Load ID S352546
- Purity: 99.7%
- Expiration date: 01 May 2020 - Key result
- Boiling pt.:
- 314.4 °C
- Atm. press.:
- 101.5 kPa
- Conclusions:
- The boiling point of MTDID 44428 was determined to be 314.4 °C at 101.5 kPa (OECD 103).
- Executive summary:
The boiling point of MTDID 44428 was determined using the capillary method of Siwoloboff. Boiling point was determined from 218 °C and 323 °C using an automated BUCHI boiling point apparatus. The average temperature of forming continuous bubbles was 314.4 °C at 101.5 kPa. The bubble onset temperature measured in this experiment is in line with tabulated boiling points and similar substances reported elsewhere, while the continuous bubble temperature was considerably greater than the other values. Notably, the continuous bubble temperature is within one degree of the value for a much larger homologous acrylate (molecular weights, 184 v 240) while the bubble onset temperatures differed sharply. It should also be noted that an instantaneous, continuous bubble stream upon insertion of the capillary was found in both of the homologous acrylates during definitive testing at a temperature 10 degrees below the reported value, which necessitated reducing the starting temperature for the definitive tests. The reason for this phenomena is not known, and the continuous bubble temperature is the guideline interpretation of boiling point. A sharp boiling point is not expected for multi-constituent substances. The study was conducted according to OECD 103 guidelines and was GLP compliant. However, based on the available information the result appears to be an aberration and is not considered reliable.
