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.
