Description of key information

A vapour pressure of 0.06923 Pascals at 20°C and 0.15287 Pascals at 25°C was determined for 1,1-DPE.
In a publication from Verevkin et al. the vapour pressure of 1,1’-DPE at various temperatures is given:
T (°C) P (Pa)
20.35 0.3893
25.05 0.6216
30.05 0.9721
35.15 1.5449
40.05 2.394
45.05 3.439
49.95 5.226
55.05 7.442
