Results and discussion
Boiling point
- Boiling pt.:
- > 224 °C
- Decomposition:
- yes
- Remarks on result:
- other: Hydrolysis and decomposition are expected to occur prior to boiling. An exact decomposition temperature could not be determined.
Any other information on results incl. tables
On heating the sample in an open beaker, a small amount of condensation was seen above the sample at 120ºC, and vapours were visible at 149ºC, although the sample did not show any signs of boiling. The test was terminated at 224ºC due to the limitations of the equipment used. No signs of boiling were noted.
Applicant's summary and conclusion
- Conclusions:
- 2-Ethylhexyl diphenyl phosphite is known to hydrolyse readily on contact with moisture. The signs of boiling seen in the open beaker apparatus can therefore be attributed to 2-ethylhexanol which is liberated by the hydrolysis of the phosphite. It can therefore be concluded that 2-ethylhexyl diphenyl phosphite decomposes or hydrolyses before the boiling point is reached.
