Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- not specified
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- not specified
- Principles of method if other than guideline:
- Thermogravimetric measurements was performed in air at a heating rate of 3 °C/min. by an automatic thermobalance.
- GLP compliance:
- no
- Type of method:
- thermal analysis
- Decomposition:
- yes
- Remarks:
- Ammonium dimolybdate begins to evolve ammonia around 150 °C, rapid evolution subsequently begins around 200 °C. At ca. 225 °C an endothermic peak was observed in the thermoanalysis (formation of ammonium octamolybdate).
- Decomp. temp.:
- > 150 - < 225 °C
- Conclusions:
- Upon heating, ammonium dimolybdate begins to evolve ammonia around 150 °C, rapid evolution subsequently begins around 200 °C. At ca. 225 °C an endothermic peak was observed in the thermoanalysis (formation of ammonium octamolybdate).

Description of key information
Decomposes from ca. 150 °C (evolution of ammonia). Formation of ammonium octamolybdate at ca. 225 °C.
Key value for chemical safety assessment
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.
