Description of key information

From water surface, the "reaction mass of butane and butene and isobutane" will rapidly evaporate into the atmosphere.. 

Key value for chemical safety assessment

Additional information

The single components of the present reaction mass are gaseous substances (calculated Henry's Law constants range from 20600 to 98200 Pa m³/mol); therefore, they will rapidly evaporate from the water surface into the atmosphere.
