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.
