Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

The Antoine coefficients for 2 -phenethyl acetate are the following:

A

C

T min (°C)

T max (°C)

7.67962

2223.86

230.819

-4

232.6

 

The Antoine equation used for vapour pressure as a function of temperature is:

Log10P = A – B/(T + C)

Where P = vapour pressure, mm Hg; A, C, C = Antoine coefficients; T = temperature,°C

Log10P =7.67962–2223.86/(20 +230.819) = 7.67962 – 2223.86/250.819 = -1.18677

P = 10(-1.18677)= 0.065 mm Hg = 8.7 Pa

Therefore, the vapour pressure of 2 -phenethyl acetate is reported to be 8.7 Pa at 20°C.

Conclusions:
The vapour pressure of 2 -phenethyl acetate is reported to be 8.7 Pa at 20°C.
Executive summary:

The vapour pressure of 2 -phenethyl acetate is reported to be 8.7 Pa at 20°C according to the Antoine Equation and Coefficients for Organic Compounds.
