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).

Description of key information

The boiling point was determined according to EU Method A.2 and OECD guideline 103 (DSC method) (Sohar, 2016).

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
193.7 °C
