Additional information
A vapour pressure determination was performed by Mitsui Chemicals, Inc., (2011, Report No.: ESD-2010 -020). The vapour pressure was determined according to OECD Method 104 and EU Method A4 and was considered to be reliable. DMI was found to have a vapour pressure 20 Pa at 25°C. This vapour is low for a liquid, for example, when compared to the vapour pressure of water which is 3169.0 Pa at 25°C (CRC Handbook of Chemistry and Physics, 73rd Edition, 6 -14).
