Tetrakis[[2,2',2''-nitrilotris[ethanolato]](1-)-N,O]zirconium

Melting point / freezing point

Link to relevant study record(s)

Reference

Endpoint:

melting point/freezing point

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

other:

Justification for type of information:

As a preliminary test the sample was placed in a refrigerator whose cooling limit was -40°C. The substance only became unpourable but no solid formed after 3 days of starge under -40°C. The melting point was therefore below -40°C.

According to Column 2 of REACH Annex VII, the study is not required and no actual determination was made.

Qualifier:

according to guideline

Guideline:

other: in- house test

GLP compliance:

no

Key result

Melting / freezing pt.:

< -40 °C

Atm. press.:

ca. 1 atm

Conclusions:

Below -40°C.

Executive summary:

Sample was placed in a refrigerator whose cooling limit was -40°C. No solid formed after 3 days of storage under -40°C. The melting point was therefore below -40°C. According to Column 2 of REACH Annex VII, the study is not required and no actual determination was made.

Description of key information

Pouring point method.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:

-40 °C

Additional information

In a preliminary test in which the test substance was placed under -40°C and no freezing was observed. The melting point was therefore below -40°C. This value was used for CSA.
