Description of key information

In a Thermogravimetric Analysis test (TGA, Chevron ILT Test 10301), the TGA analysis indicated:
5% loss @ 189 °C
50% loss @ 246 °C
95% loss @ 270 °C
The TGA testing procedure (conducted in a nitrogen atmosphere) attempts to estimate volatility upon heating in a non-oxidizing atmosphere.
Since tetrapropenyl phenol consists of alkyl phenol analogues that have alkyl side chains that range from C3-C15, it is more appropriate to report a boiling range rather than a single boiling point. A recent study conducted by an HERTG member company with a commercial (>99% purity) sample by a thermogravimetric analysis method gave the preferred value of 189-270 °C (Seary 2005).

Key value for chemical safety assessment

Additional information

A reliability rating of 2 was assigned to this study, according to the criteria of Klimisch, 1997 as the information was obtained from an in house study conducted to Chevron ILT Test 10301 method.
