Additional information

There is one key study available investigating the vapour pressure of diphenyl carbonate (Bayer, 1998). The study was assigned a reliability score of 2 in line with the criteria of Klimisch et al. (1997).

The vapour pressure of diphenyl carbonate was determined according to a dynamic method (Roeck) for a range of temperatures between 161 °C and 312 °C. The results were correlated according to Antoine Constants' Law and the vapour pressure calculated at temperatures of 20, 40 and 60 °C.

The vapour pressure was determined to be 0.014 Pa at 20 °C, 0.17 Pa at 40 °C and 1.40 Pa at 60 °C. According to the standardised guidelines, vapour pressure is measured at 25 °C; the value at 20 °C has therefore been selected as key due to being the value closest to environmentally relevant conditions.
