Description of key information

The study has been performed in accordance to the OECD Guidelines for Testing of Chemicals No. 104 "Vapour Pressure Curve" resp. test guideline 92/69/EEC A.4. Instead of the gas saturation method, which is recommended in the lowest range, the thermogravimetry method (diffusion controlled evaporation) is used. 
At a temperature of 181.2 °C evaporation of methylnitroguanidine begins in the 1.scan of thermogravimetry, corresponding to a vapour pressure of 11 Pascal.
Vapour pressure is determined at 20 °C with 0.0000003 Pa and at 25 °C with 0.0000007 Pa (extrapolated).
