Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
242.7 K

Additional information

The melting point of 1,1,1 -tricloroethane is reported to be between -33.0 and -30.4 °C (ATSDR 2006) or around -30.4°C ( WHO 2003, NAS-COT 2000), or 242.7 K (Seybold 1986). As the melting point is below the lower limit of -20 °C, no additional testing is required.1,1,1 -trichloroethane is liquid at room temperature.
