- Atm. press.:
- 1 013 hPa
- Remarks on result:
- other: No melting/freezing point could be determined for the test item down to a temperature of -100 °C.
- Conclusions:
- MTMA has no melting/freezing point at atmospheric pressure (1013 hPa) down to a temperature of -100°C.
- Executive summary:
The melting point of MTMA was determined according to OECD Guideline 102, adopted 27th July 1995, and EU Method A.1, May 2008 by differential scanning calorimetry. MTMA has no melting/freezing point at atmospheric pressure (1013 hPa) down to a temperature of -100°C.
Reference
The test item was cooled down from 25°C to -100°C with a cooling rate of 10 K/min. After 10 min the test item was heated from -100°C to 25°C with a heating rate of 10 K/min. Neither during cooling nor heating any thermal effects were observed.
The test item MTMA has no melting/freezing point at atmospheric pressure (1013 hPa) down to a temperature of -100°C.
Description of key information
MTMA has no melting/freezing point at atmospheric pressure (1013 hPa) down to a temperature of -100°C (OECD Guideline 102/EU Method A.1).
Key value for chemical safety assessment
Additional information
The melting point of MTMA was determined according to OECD Guideline 102, adopted 27th July 1995, and EU Method A.1, May 2008 by differential scanning calorimetry. MTMA has no melting/freezing point at atmospheric pressure (1013 hPa) down to a temperature of -100°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
