Materials and methods

Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
Approx 250g of sample was heated in a round bottom flask with the heat source provided from a heating mantle and agitation from an overhead mechanical stirrer with a paddle in the flask. A condenser was used to collect any distillate from the substance with one thermometer measuring the temperature of the test substance and a second thermometer to monitor the condensate temperature. The sample was heated through a range of ambient to 320°C.
GLP compliance:
no

Applicant's summary and conclusion

Conclusions:
The sample was observed to decompose before the boiling point was reached.

The sample was not observed to ignite in the temperature range up to 320°C, it can therefore be concluded that the autoflammability temperature of tri(2-propylheptyl)phosphite is greater than 320°C.
Executive summary:

The sample was observed to decompose before the boiling point was reached.

The sample was not observed to ignite in the temperature range up to 320°C, it can therefore be concluded that the autoflammability temperature of tri(2-propylheptyl)phosphite is greater than 320°C
