Identity: carbamic acid, butylester (93.5 %), n-butanol (2.7%), ?n-Butylcarbamoyl carbamate (2.2 %), dibutyl carbonate (1.2 %) - Key result
- Boiling pt.:
- 193.7 °C
- Decomposition:
- yes
- Decomp. temp.:
- > 300 °C
- Conclusions:
- Under the study condtions, the boiling point of the test substance was determined to be 193.7°C (evaporation). Decomposition of the main constituents appeared above approx. 300°C (DSC method).
- Executive summary:
A study was conducted to determine the boiling point of the test substance, according to EU Method A.2 and OECD guideline 103 (DSC method). Duplicate specimens of the test substance were encapsulated in Al pans with pierced lids. Instrument were calibrated with an indium and zinc standard following internal procedure. Under the study condtions, the boiling point of the test substance was determined to be 193.7°C (evaporation). Decomposition of the main constituents appeared above approx. 300°C (Sohar, 2016).
