Description of key information

The particle size distribution of tetrachlorophthalic anhydride was evaluated according to OECD TG 110, Method B: Particle Size Distribution/Fibre Length and Diameter Distributions. All particles with a mean diameter less than 100 μm have a mass fraction of 2.57 %. 0.00 % of this mass fraction has a mean diameter less than 4 μm. The mass median diameter is 110.0 µm (spherical volume) and 105.0 µm (cubical volume).
