Description of key information

1a) Boiling point: 234.4 °C [Adapted Stein and Brown Method; calculation with MPBPVPWIN v1.43 (EPIWIN software by US-EPA)]
1b) Boiling point: 261 °C [exp. data; MPBPWIN 1.43 (EPIWIN software by US-EPA)]
2) Boiling point: 261°C [GESTIS substance database]
3) Boiling point: 260.8±9.0 °C (at 760 Torr = 101325 Pa) [Calculation (ACD Labs software v9.1)]

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
261 °C

Additional information

The boiling point of the substance 4-phenylbutenone was calculated to be 234.42 °C by taking the adapted Stein and Brown Method of the MPBPWIN program v1.43 into account. Finally, an experimental value is also stated in the database of the program: 261 °C. In the GESTIS substance database a boiling point of 261 °C is reported, too. Further, the calculation with another program (ACD Labs software v9.1) resulted in a boiling point of 260.8±9.0 °C, which also confirms this result. Therefore, 261 °C was taken as key value for chemical safety assessment.
