EC number: - | CAS number: -
Flash point
Administrative data
- Endpoint:
- flash point of flammable liquids
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Justification for type of information:
- The substance has a very low volatility and is not expected to be able to generate a flammable concentration. This estimation approach based on the alcohol compotent of the phosphite, which is also a hydrolysis product.

Results and discussion
Flash point
- Flash point:
- >= 100 °C
- Atm. press.:
- 1 atm
- Remarks on result:
- not measured/tested
- Remarks:
- Estimation based on 2-propylheptanol.
Any other information on results incl. tables
Based on the low estimated vapour pressure of tris(2-propyheptyl) phosphite, the flash point of the pure substance is expected to be high. Phosphites of this type are known to hydrolyse at high temperatures in contact with atmospheric moisture. In the case of tris(2-propyheptyl) phosphite this hydrolysis liberates 2-propylheptanol.
The flash point of 2-propylheptanol is100ºC (as stated in the REACH dossier 10042-59-8)
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The flash point of tris(2-propyheptyl) phosphite can be stated to be greater than or equal to 100ºC.
- Executive summary:
Based on the low estimated vapour pressure of tris(2-propyheptyl) phosphite, the flash point of the pure substance is expected to be high. Phosphites of this type are known to hydrolyse at high temperatures in contact with atmospheric moisture. In the case of tris(2-propyheptyl) phosphite this hydrolysis liberates 2-propylheptanol.
