Description of key information

The relative density of Tetrachlorophthalic anhydride is 1.98 at 21 °C.

Key value for chemical safety assessment

Relative density at 20C:

Additional information

The result is given as density in unit g/cm³. For assessment, the relative density, defined as follows, is preferred.

The relative density D204 of solids or liquids is the ratio between the mass of a volume of the substance, determined at 20 °C, and the mass of the same volume of water, determined at 4 °C. At this temperature the density of water is 0.999975 g/cm³. To convert the density to relative density the following formula is used: D204 = pSubstance (20°C) / pWater (4°C). The relative density has no dimension. It is assumed that the reported density at 21°C shows no significant deviation to the density at 20°C.
