Description of key information

Appearance / physical state / colour:

The appearance of 4-chloro-1-methylpiperidinium chloride was observed to be white-slightly pale yellow colored, odourless organic solid crystal powder.

Melting point/ Freezing point:

The melting point of 4-chloro-1-methylpiperidinium chloride was determined as 163-165 °C.

Boiling point:

The boiling point of 4-chloro-1-methylpiperidinium chloride was determined as 47-48 °C at pressure 1333.22 Pa.

Density:

The density of 4-chloro-1-methylpiperidinium chloride was determined as 1.04 g/cm3

Particle size distribution (Granulometry):

The particle size distribution of 4-chloro-1-methylpiperidinium chloride 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:

The estimated vapour pressure of the substance 4-chloro-1-methylpiperidinium chloride at 25deg C was 159 Pa.

Partition Coefficient:

KOWWIN V1.68 was used to estimate the octanol water partition coefficient of the test substance 4-chloro-1-methylpiperidinium chloride. The estimated Log Pow is  1.58. This partition coefficient value indicate that the test chemical 4-chloro-1-methylpiperidinium chloride is hydrophilic in nature.

Water solubility:

The estimated water solubility of substance 4-chloro-1-methylpiperidinium chloride at 25 deg C was 15380 mg/l.

Surface tension:

The surface tension for the chemical 4-chloro-1-methylpiperidinium chloride was predicted to be 31.9 ± 5.0 dyne/cm.

Flash point:

Based on the Calculation done using  scientifically verified and validated formulas / equations, the flash point of chemical 4-chloro-1-methylpiperidinium chloride was estimated to be -26.401 degree C.

Autoflammability:

4-chloro-1-methylpiperidinium chloride did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 4-chloro-1-methylpiperidinium chloride is not auto-flammable.

Flammability:

4-chloro-1-methylpiperidinium chloride 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-chloro-1-methylpiperidinium chloride is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus  4-chloro-1-methylpiperidinium chloride 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 there are no chemical groups present in the molecule which are associated with oxidizing properties and hence the classification procedure does not need to be applied.
