Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- November 2017 - January 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7200 (Melting Point / Melting Range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: United States Environmental Protection Agency, Office of Prevention, Pesticides and Toxic Substances (TS-7101)
- Deviations:
- no

- no
- Type of method:
- capillary method
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- >= 230.1 - <= 230.9 °C
- Conclusions:
- The 3 samples of the substance decomposed at 230.4°C, 230.1°C and 230.9°C. The average decomposition temperature of the three samples was 230.5°C
- Executive summary:
The melting point of Aryl sulphonate condensate was determined using the OECD guideline, No. 102 "Melting Point/Melting Range, Adopted: 27 July 1995 and the United States Environmental Protection Agency, Office of Prevention, Pesticides and Toxic Substances (TS-7101), Product Properties Test Guidelines, OPPTS 830.7200, "Melting Point/Melting Range", EPA 712-C-98-033 March 1998. Using the capillary method this study tested three samples of Aryl sulphonate condensate to conclude that it does not melt, instead it decomposes. The 3 samples of the substance decomposed at 230.4°C, 230.1°C and 230.9°C. The average decomposition temperature of the three samples was 230.5°C (Standard deviation (+-) 0.4), with 0.17% RSD.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
