Description of key information
Appearance / physical state / colour:
In several study reports the test item 3,4 -Dichlorobenzonitrile is characterised as white solid at standard conditions.
Melting point / freezing point:
The melting point of 3,4 -Dichlorobenzonitrile was determined applying differential scanning calorimetry. The peak of the endothermic heat fluxes were reported and the melting point of 3,4 -Dichlorobenzonitrile is 74°C.
Boiling point:
The boiling point of 3,4 -Dichlorobenzonitrile was determined applying differential scanning calorimetry. The peak of the fluxes were reported and the boiling point of 3,4 -Dichlorobenzonitrile is 146-147°C.
Density:
The reported density for 3,4 -Dichlorobenzonitrile is 1.349 g/cm³ at 20°C, respectively 1.34 g/mL at 22°C.
Partition coefficient:
The partition coefficient (n-octanol/water - Kow value) of 3,4-Dichlorobenzonitrile was determined to be 5.7 x 10^2 (log Kow= 2.8) using the HPLC method (OECD 117).
Auto flammability:
A test for dusty 3,4-Dichlorobenzonitrile is availabale evaluating the auto flammability on hot surface for deposited 3,4-Dichlorobenzonitrile. No auto ignition of deposited 3,4-Dichlorobenzonitrile dust occured on surfaces until 360°C.
Flammability:
Due to three test results 3,4 -Dichlorobenzonitrile could not be ignited. Because of this the test substance can be excluded from the hazard class "flammable solids" and does not have to be classified.
Explosiveness:
The mechanical sensitivity (shock and friction) according to a test method similar to guideline A.14 was determined. The tests for mechanical sensitivity to friction and shock showed no explosive properties of 3,4-Dichlorobenzonitrile.
Furthermore a determination of the lowest explosion border of 3,4-Dichlorobenzonitrile equivalent to DIN 51 649 Part 1(12/86) was performed. A lowest explosion border of 1,5 Vol-% (107.4 g/m3) was measured.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
