Description of key information

 The vapour pressure of DMT (based on extrapolation from reduced pressure boiling point measurements) is estimated to be 0.000139 kPa at 20 degrees C.  
The MPBPVP v1.43 QSAR model provides a vapour pressure estimate of 0.0331 Pa at 25 degrees C for dimethyl terephthalate (Modified Grain method). Additionally, MPBPVP provides a measured vapour pressure value of 1.33 Pa at 25 degrees C for dimethyl terephthalate, retrieved from the database used to construct the QSAR model.
