Key value for chemical safety assessment

Additional information

There is one reliable key study for this endpoint. In this study (Habeck C., 2010), the vapor pressure of Reaction mass of Dimethyl adipate (CAS627-93-0), Dimethyl glutarate (CAS1119-40-0) and Dimethyl succinate (CAS106-65-0) was determined according to the EECDirective 92/69, A.4 (2008), to the OECD guideline No. 104, (2006) and to the Council Regulation EC No. 761/2009, A4 (2009) using the gas saturation method. The study was compliant with the GLP principles.

The vapor pressure of Reaction mass of Dimethyl adipate (CAS627-93-0), Dimethyl glutarate (CAS1119-40-0) and Dimethyl succinate (CAS106-65-0) was measured at test temperatures of 30 °C, 40 °C and 50 °C and was determined to be

 

 

30 °C

40 °C

50 °C

Dimethyl adipate

7.3 x 10-1Pa

1.7 x 100Pa

3.7 x 100Pa

Dimethyl glutarate

1.3 x 101Pa

2.6 x 101Pa

5.5 x 101Pa

Dimethyl succinate

1.4 x 101Pa

2.7 x 101Pa

5.4 x 101Pa

 

Calculation of the vapor pressure at 25 °C by extrapolation based upon the simplified Clausius-Clapeyron equation resulted in a vapor pressure of :

Dimethyl adipate: 0.47 Pa at 25 °C

Dimethyl glutarate: 8.5 Pa at 25 °C

Dimethyl succinate: 9.4 Pa at 25 °C.
