Description of key information
The melting point of solid BTMAC is reported to be between 236 and 243 °C. It starts to decompose at 239°C.
The freezing point of a ca. 60% solution of BTMAC in water was found to be < -50 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 243 °C
Additional information
The melting point of solid BTMAC is reported to be between 236 - 239 °C and 241 - 243 °C. This seems to be related to either the purity of the tested BTMAC or related to different measurement techniques.
Several publications report that BTMAC starts to decompose at 239 °C.
The freezing point of a ca. 60% solution of BTMAC in water was found to be < -50 °C.
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.
