Description of key information

Density (tetramethyl orthosilicate): 1.03 g/cm3 at 20°C (DIN 51757)

Key value for chemical safety assessment

Additional information

Three reliable data are available for tetramethyl orthosilicate. A density value of 1.03 g/cm3 at 20°C was reported in two of the three available data (Evonik 2007, Lide 1993) which are used in a weight of evidence approach. An estimated density of 0.98 g/cm3 was determined for the substance using a validated prediction method. The predicted value is in good agreement with the other available results.
