Particle size distribution:

The particle size distribution of test chemical 1-chloro-3-nitrobenzene was determined by Granulometric analysis with Rotap sieve shaker. The particle size distribution was determined to be150 micron.

Vapour pressure:

Vapour pressure of test chemical 1 -chloro-3 -nitrobenzene is determine to be 0.011 hPa at 20 Deg C & 0.019 hPa at 25 Deg C.

Partition coefficient:

Partition coefficient of test chemical 1 -chloro-3 -nitrobenzene is determine to be 2.49.

From this partition coefficient value it is concluded that chemical is hydrophilic in nature.

Water solubility:

The water solubility determination of test chemical 1-chloro-3-nitrobenzene was done as per the OECD guideline 105 by spectrophotometric analytical method as per OECD 101. The solubility of test chemical 1-chloro-3-nitrobenzene in water was determine to be 359.64 mg/L at 25°C.

Thus the test chemical 1-chloro-3-nitrobenzene is considered to be moderately soluble.

Surface tension:

Surface tension of test chemical1 -chloro-3 -nitrobenzene is determinne to be 43.63 mN/m.
