relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

28 September 2010 to 25 November 2010

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

other: GLP Compliant, guideline study, available as unpublished report, acceptable without restrictions

Qualifier:

according to guideline

Guideline:

other: N.4 (Modified method) Self Heating Substances test

Deviations:

yes

Remarks:

the test item was only available in very limited amounts, therefore, in order to obtain as much information as possible on the self-heating properties of the test item a modified procedure was employed

GLP compliance:

yes (incl. QA statement)

Key result

Relative self-ignition temperature:

195 °C

Remarks on result:

other: No self-heating when at 140 °C for 24 hrs, but self-heating at 195 °C on increase in oven temperature was increased from 140 to 400 °C.

No self-heating when at 140 °C for 24 hrs, but self-heating at 195 °C on increase in oven temperature was increased from 140 to 400 °C.

Conclusions:

Palladium (II) acetate showed no self-heating when at 140 °C for 24 hrs, but self-heating at 195 °C on increase in oven temperature was increased from 140 to 400 °C.

Executive summary:

This is a GLP compliant, guideline study which is considered suitable for use as the key study for this endpoint. Palladium (II) acetate showed no self-heating when at 140 °C for 24 hrs, but self-heating at 195 °C on increase in oven temperature was increased from 140 to 400 °C.

Additional information

O’Connor and Woolley (2011) is a GLP compliant study following a modified N4 method, which is considered suitable for use as the key study for this endpoint. Palladium (II) acetate showed no self-heating when at 140 °C for 24 hrs, but self-heating at 195 °C on increase in oven temperature was increased from 140 to 400 °C.

Vill (2000) is a guideline study considered suitable for use as the key study for this endpoint. Palladium (II) acetate reacts exothermically from 174.5 °C and at an oven temperature of about 180 °C a peak temperature of about 325 °C was measured.
