Description of key information

Appearance:

Based on available data from authoritative database,the chemical sodium 4-(2-methylprop-2-en-1-yl)benzenesulfonate was observed to be an organic solid dry powder or wet solid in appearance.

Melting point:

Based on the prediction done using the EPI Suite MPVPBP V1.43,the melting point of chemical sodium 4-(2-methylprop-2-en-1-yl)benzenesulfonate was predicted. The melting point of chemical sodium 4-(2-methylprop-2-en-1-yl)benzenesulfonate was estimated to be 242 ˚C.

Boiling point:

Based on the prediction done using the EPI Suite MPVPBP V1.43,the boiling point of chemical sodium 4-(2-methylprop-2-en-1-yl)benzenesulfonate was predicted. The boiling point of chemical sodium 4-(2-methylprop-2-en-1-yl)benzenesulfonate was estimated to be 564 ˚C.

Density:

Based on prediction done using ACD/I-Lab 2.0, the density of chemical sodium 4-(2-methylprop-2-en-1-yl)benzenesulfonate was estimated to be 1.263 ± 0.06 g/cm3.

Particle size distribution:

The particle size distribution of sodium 4-(2-methylprop-2-en-1-yl)benzenesulfonate was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was determined to be in the range of 150 micron to 53 micron.

Vapour pressure:

Using the EPI Suite MPVPBP V1.43,the vapour pressure of chemical sodium 4-(2-methylprop-2-en-1-yl)benzenesulfonate was predicted.

The vapour pressure of chemical sodium 4-(2-methylprop-2-en-1-yl)benzenesulfonate was estimated to be 3.79E-10 Pa at 25 degree C.

Partition coefficient:

Based on the available data from modeling database EPI suite using the KOWWIN V1.68 programme, The partition coefficient (logPOW) of the test chemical Sodium 4-(2 -methylprop-2 -en-1 -yl)benzenesulfonate was estimated to be -1.01. On the basis of this estimated value, chemical Sodium 4-(2-methylprop-2-en-1-yl)benzenesulfonate can be considered to be hydrophilic in nature.

Water solubility:

WSKOW v1.42 was used to estimate the water solubility of the chemicalsodium 4-(2-methylprop-2-en-1-yl)benzenesulfonatee).

The estimated water solubility of chemical sodium 4-(2-methylprop-2-en-1-yl)benzenesulfonate at 25 deg C was  211000 mg/l.

Thus, it can be concluded that sodium 4-(2-methylprop-2-en-1-yl)benzenesulfonate is highly soluble in water.

Surface tension:

The study does not need to be conducted because surface activity is not a desired property of the material.

(In accordance with column 2 of Annex VII of the REACH regulation, the study need only be conducted if surface activity is a desired property of the chemical. The chemical sodium 4-(2-methylprop-2-en-1-yl)benzenesulphonate is used as a processing aid and in water treatment. For these use, surface activity is not a desired property. Hence this study was considered for waiver. )

Flash point:

Based on the calculation done using  scientifically verified and validated formulas / equations ,the flash point of chemical sodium 4-(2-methylprop-2-en-1-yl)benzenesulfonate was estimated to be 357.154 degree C.

Auto flammability:

Sodium 4-(2-methylprop-2-en-1-yl)benzenesulfonate did not catch fire on being exposed to air at room temperature of 27°C and pressure of 966 hPa. This indicates that  sodium 4-(2-methylprop-2-en-1-yl)benzenesulfonate  is not auto-flammable.

Flammability:

Sodium 4-(2-methylprop-2-en-1-yl)benzenesulfonate 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 sodium 4-(2-methylprop-2-en-1-yl)benzenesulfonate is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus sodium 4-(2-methylprop-2-en-1-yl) benzenesulfonate 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.

Oxidising properties:

The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied.
