The flash point of Bis(2-chloroethyl) ether was determined based on EU A.9 under GLP. The flash point of the test item was 81.0 °C ± 1.0 °C at 1013.25 hPa (corrected value for atmopsheric pressure).

Description of key information

The flash point of Bis(2-chloroethyl) ether was determined to be 81.0°C ± 1.0 °C

Key value for chemical safety assessment

Flash point at 101 325 Pa:

81 °C

Additional information

Available data from the literature has only a moderate validity and available figures ranged from 55 to 185°C. In order to obtained a reliable estimate, the flash point of Bis(2-chloroethyl) ether was experimentally determined based on EU A.9 under GLP. The flash point of the test item was 81.0 °C ± 1.0 °C at 1013.25 hPa (corrected value for atmopsheric pressure). Accordingly, the substance is classified as Flammable Liquid Category IV according to GHS-UN criteria.
