Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint summary
Administrative data
Description of key information
Appearance:
Chemical Divinylbenzene is appear as a pale straw colored liquid.
Freezing point:
Freezing point of chemical Divinylbenzene is determine to be -45 Deg C.
Boiling Point:
Boiling point of chemical Divinylbenzene is determine to be 195 Deg C.
Density:
Density of chemical Divinylbenzene is determine to be 0.918 g/cm3 at temperature 25 Deg C.
Particle size distribution:
The study does not need to be conducted because the substance is marketed or used in a non solid or granular form. Chemical Divinylbenzene is determine to be appear as a colorless liquid.
Vapour pressure:
Vapour pressure of chemical Divinylbenzene is determine to be 93.32 Pa at temperature 20 Deg C.
Partition coefficient:
Based on the available data from handbook and secondary source,the partition coefficient (log Pow) value of the substance 1,2-di(ethenyl)benzene was estimated to be 3.6. On the basis of this value, chemical 1,2-di(ethenyl)benzene can be considered to be hydrophobic in nature.
Water solubility:
Water solubility of chemical Divinylbenzene is determine to be 50 mg/L. From this value it is concluded that chemical Divinylbenzene is slightly soluble in water.
Surface tension:
Surface tension of chemical Divinylbenzene is determine to be 32.10 mN/m at temperature 25 Deg C.
Flash point:
Flash point of chemical Divinylbenzene is determine to be 62 Deg C.
Auto flammability:
Divinylbenzene did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that Divinylbenzene is not auto-flammable.
Flammability:
Divinylbenzene does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that Divinylbenzene is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Divinylbenzene was considered non-flammable.
Explosiveness:
The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties.
Oxidizing properties:
The study does not need to be conducted because the substance is a liquid.

The study does not need to be conducted because the substance is marketed or used in a non solid or granular form. Chemical Divinylbenzene is determine to be appear as a colorless liquid.
Vapour pressure:
Vapour pressure of chemical Divinylbenzene is determine to be 93.32 Pa at temperature 20 Deg C.
From other reliable sources & authoritative databases vapour pressure of chemical Divinylbenzene is concluded to be 90 Pa at temperature 20 Deg C, 88.39 Pa at temperature 25 Deg C, 77.19 Pa at temperature 25 Deg C & 133 Pa at temperature 32.7 Deg C.
Partition coefficient:
Based on the available data in a key study from handbook and secondary source, the partition coefficient (log Pow) value of the substance 1,2-di(ethenyl)benzene was estimated to be 3.6.
Another supporting studies from authoritative and modelling database indicates that the partition coefficient (log Pow) value of the substance 1,2-di(ethenyl)benzene was estimated to be 3.8.
Thus, based on the available information, the logPow valueof the test substance 1,2-di(ethenyl)benzene ranges from 3.6 to 3.8, respectively and thus chemical 1,2-di(ethenyl)benzene can be considered to be hydrophobic in nature.
