Key result

Test no.:

#1

Temp.:

20 °C

Vapour pressure:

< 0 Pa

The weight loss of the test substance at 210°C to 240°C was lower than the weight loss of benzo(ghi)perylene at the same temperatures. From this, it was concluded that the vapour pressure of the test substance is < 1.33 x10^-8 Pa = <1.00 x10^-10 mm Hg.

Conclusions:

The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of Decanoic acid, mixed esters with dipentaerythritol, octanoic acid and valeric acid. The vapour pressure of the test substance at 20°C (293K) was < 1.33 x 10E-8 Pa = < 1.00 x 10E-10 mm Hg.

Description of key information

The vapour pressure of substance EC# 270-470-1 was determined to be  < 1.33x10-8 Pa at 20°C.

Key value for chemical safety assessment
