Boiling point of chemical 4-tert-butylcyclohexanol is determine to be 226 Deg C.

Density:

Density of chemical 4-tert-butylcyclohexanol is determine to be 0.9052 g/cm3 at temperature 25 Deg C.

Particle size distribution:

The particle size distribution of 4-tert-butylcyclohexanol 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:

Vapour pressure of 4-tert-butylcyclohexanol is determine to be 2.0138 hPa at temperature 65 Deg C & 3999.4 hPa at temperature 262.74 Deg C.

Partition coefficient:

Based on the available data from handbook, authoritative and modelling databases, the partition coefficient (log Pow) value of the substance 4-tert-Butylcyclohexanol was estimated to be 3.23. On the basis of this value, chemical 4-tert-Butylcyclohexanol can be considered to be hydrophobic in nature.

Water solubility:

Water solubility of 4-tert-butylcyclohexanol is determine to be less than 100 mg/L at temperature 20 Deg C. From this value it is conclude that 4-tert-butylcyclohexanol is slightly soluble in water.

Surface tension:

Surface tension of 4-tert-butylcyclohexanol is determine to be 0.01845 N/m at temperature 147.77 Deg C.

Flash point:

Flash point of 4-tert-butylcyclohexanol is determine to be 105 Deg C.

Auto flammability:

Auto flammability of 4-tert-butylcyclohexanol is determine to be 420 Deg C.

Flammability:

4-tert-butylcyclohexanol 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 4-tert-butylcyclohexanol is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 4-tert-butylcyclohexanol 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.

Oxidizing properties:

The study does not need to be conducted because the substance is a solid.
