Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Not reported
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Non-GLP, non-guideline, published in peer reviewed literature, predates implementation of GLP and study guidelines but otherwise acceptable for assessment.
Principles of method if other than guideline:
Thermogravimetric analysis of hexachloroplatinic acid in He with identification of the intermediate phases chemically and crystallographically
GLP compliance:
no
Type of method:
other: Thermogravimetric analysis of hexachloroplatinic acid in He with identification of the intermediate phases chemically and crystallographically
Boiling pt.:
220 °C
Atm. press.:
other: No data
Decomposition:
yes
Remarks on result:
other: The starting temperature was 25°C. Between 25°C and 125°C water was lost from the compound. By 220°C the hexachloroplatinic acid has decomposed to form PtCl4

No further details

Conclusions:
Hexachloroplatinic acid decomposes before boiling. The decomposition point is <200 °C.
Executive summary:

This study predates GLP and there is no established guideline to determine the decomposition temperature. The study is well reported with both the thermogram presented and the identification of the decomposition products throughout the temperature range. The study in considered reliable to establish that hexachloroplatinic acid decomposes before boiling. The decomposition point is < 200 °C.

Description of key information

Hexachloroplatinic acid decomposes before boiling.  The decomposition point is <200 °C.

Key value for chemical safety assessment

Additional information

The study by Schweizer & Kerri (1978) is well reported with both the thermogram presented and the identification of the decomposition products throughout the temperature range. The study in considered reliable to establish that hexachloroplatinic acid decomposes before boiling.

Hexachloroplatinic acid decomposes before boiling. The decomposition point is <200 °C.
