2-oxocyclohexane-1,1,3,3-tetrapropionic acid

Endpoint summary

Additional information

TKK13332 is a white to yellowish solid.

The melting poitn was determined to be 178.2°C. As the test item decompose (200 - 400°C), no value for boiling point could be determined. The density of the test item was determined to be 1.40 +/- 0.01 g/mL.

Granulometry data acquired for the test item is :

Percentage of test item with an inhalable particle size <100 µm (sieve method): 56.5%

Percentage of test item with a thoracic particle size <10.0 µm (Cascade Impactor): 2.54%

Percentage of test item with a respirable particle size <5.5 µm (Cascade Impactor): 0.246%

The vapor pressure of TKK 13332 has been determined to be < 1.3E-04 Pa at 25 °C.

The partition coefficient was found to be 2.17 x 10^-2at 23.3 ± 0.5°C, log₁₀P_ow-1.67, at pH 5 and the water solubility to be 0.30 % at 20°C.

The surface tension (not a properties which is expected), flash point (because the test item is a solid) and auto-flammability (because of the low melting point) studies were waived.

The test item has neither flammable properties, explosives properties and oxidising properties.
