Description of key information

Appearance:

Based on available data from handbook and reliable sources it is concluded that the chemical chloral physically appear in oily liquid  with pungent odour.

Melting point:

Based on available data from reliable soures such as authoritative database and handbbok,the freezing  point of  chemical chloral is determined to be -57.5 deg C

Boiling point:

Based on available data from reliable soures such as authoritative database and handbbok,the boiling  point of  chemical chloral is determined to be 97.8 deg C.

Density:

Based on available data from reliable sources such as authoritative database and handbook,the density of chemical chloral was determined to be 1.510 g/cm3  at 20 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

Vapour pressure:

Based on available data from reliable sources such as authoritative database and handbbok,the vapour pressure of chemical chloral was determined to be 4.666 kpa at 20 deg C.

Partition coefficient:

Based on available data from reliable sources such as authoritative database and handbook,the partition coefficient of chemical chloral is determined to be 0.99.

Water solubility:

Based on available data from reliable sources such as authoritative database and handbook,the water solubility of chemical chloral was determined to be 8300000 mg/l at 25 deg C.

Surface tension:

Based on available data from reliable handbook,the surface tension value of chemical chloral was determined to be 0.02534 N/m.

Flash point:

Based on available data from various reliable sources such as authoritative database and handbook,the flash point of chloral is determined to be 75 °C.

Auto flammability:

Chloral ignites only when the flame of bunsen burner having temperature of 950°C is brought in contact with it.Thus it can be concluded that substance is flammable only at high temperature of about 950°C.

Flammability:

Chloral 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 Chloral is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Chloral was considered non-flammable for chemical safety assessment.

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 the organic substance contains oxygen or halogen atoms which are chemically bonded only to carbon or hydrogen and hence, the classification procedure does not need to be applied
