Materials and methods

Test guideline

Qualifier:

equivalent or similar to guideline

Guideline:

OECD Guideline 103 (Boiling Point)

Deviations:

yes

Remarks:

Thermogravimetric analysis (TGA) is used to determine selected characteristics of materials that exhibit either mass loss or gain due to decomposition.

Principles of method if other than guideline:

Thermogravimetric analysis according to OECD 104:
The method is based on the determination of accelerated evaporation rates for the test substance at elevated temperatures and ambient pressure using thermogravimetry. The evaporation rates vT result from exposing the selected compound to a slowly flowing inert gas atmosphere, and monitoring the weight loss at defined isothermal temperatures T in Kelvin over appropriate periods of time.

GLP compliance:

no

Type of method:

other: Thermogravimetric analysis

Applicant's summary and conclusion

Conclusions:

The boiling point of the test item was determined according to OECD 103 with accetable restrictions, using thermogravimetric analysis, which may be considered as a scientifically reasonable approach, and hence the results can be considered to be reliable. As the temperature increases, various components of the sample may vaporize or decompose and the weight percentage of each resulting mass change can be measured. The test item does not have a boiling point but decomposes. Decomposition starts around 180 °C, the peak for decomposition temperature is 323.7 °C.

Executive summary:

Boiling Point was aimed to be determined via OECD guideline 103, employing thermogravimetric analysis. The test item does not have a boiling point but decomposes. Decomposition starts around 180 °C, the peak for decomposition temperature is 323.7 °C.
