Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- Testing conducted between 16 May 2008 and 02 Sepetember 2008
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Study conducted to GLP and in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not effect the quality of the relevant results.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- ASTM E537-76
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Boiling pt.:
- >= 602 - <= 644 K
- Atm. press.:
- 101.6 kPa
- Decomposition:
- no
- Conclusions:
- The boiling range of the test material has been determined to be 602 to 644 +/- 0.5K at 101.6 kPa
- Executive summary:
Method:
The determination was carried out by differential scanning calorimetry (DSC) using the procedure specified in ASTM E537 -76, Method A2 of Commisision Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).
Result:
The boiling range of the test material has been determined to be 602 to 644 K at 101.6 kPa
- Endpoint:
- boiling point
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Justification for type of information:
- 1. HYPOTHESIS FOR THE ANALOGUE APPROACH
It is proposed that the structural similarity and properties of the target substance and the structural analogue (sources substance) are sufficiently close for there to be a reasonable expectation of similar effects.
2. SOURCE AND TARGET CHEMICAL(S) (INCLUDING INFORMATION ON PURITY AND IMPURITIES)
Source chemical:
Reaction mass of 3-[3-(1,1,1,3,5,5,5-heptamethyltrisiloxan-3-yl)propoxy]-2-hydroxypropyl methacrylate and 1-[3-(1,1,1,3,5,5,5-heptamethyltrisiloxan-3-yl)propoxy]-3-hydroxypropan-2-yl methacrylate (EC 700-334-3)
Target chemical:
Reaction mass of 3-[3-(9-butyl-1,1,3,3,5,5,7,7,9,9-decamethylpentasiloxanyl)propoxy]-2-hydroxypropyl 2-methylprop-2-enoate and 1-[3-(9-butyl-1,1,3,3,5,5,7,7,9,9-decamethylpentasiloxanyl)propoxy]-3-hydroxypropan-2-yl 2-methylprop-2-enoate (EC 700-043-1)
3. ANALOGUE APPROACH JUSTIFICATION
It is concluded that the structural similarity, common functional groups and properties of the target substance and the structural analogue (sources substance) are sufficiently close for there to be a reasonable expectation of similar effects.
4. DATA MATRIX
