Additional information

A vapour pressure study on DMDS has been monitored in 2005 ( Klimisch 1) and a vapour pressure result has been found in the Physical and thermodynamic Properties of Pure chemicals Data compilation. Those two results are conherent :

- study report : the determination of the vapour pressure has been performed according to the EC method A.4 and OPPTS 830.7950. the vapour pressure assessed in this study is 38.6 hPa at 25°C and 30.0 hPa at 20°C

- handbook : Result is 38.3 hPa at 25°C
