Four measurements were firstly performed at temperatures between 23.0 and 45.0°C. However, only one determination was exploitable. Results obtained from determinations 3 and 4 showed amass[AM1] increase. Considering a pollution of the furnace, a pyrolysis was performed and two more determinations were performed. However, no exploitation was possible.

In conclusion, no value of vapour pressure could be determined for 2-AMINOETHANOL HYDROBROMIDEas no repeatable values were obtained. However, considering the vapour pressure obtained for determination 1 (0.46 Pa at 20.0°C) and estimated values of 2-aminoethanol (35.6 Pa at 20.0°C) and 2-aminoethanol hydrobromide (non-salt form) (5.26 .10-6Pa at 20.0°C) obtained with EPIsuite software, we can assess that the 2-AMINOETHANOL HYDROBROMIDE owns a low vapour pressure.

Conclusions:
The estimated vapour pressure value of 2-aminoethanol hydrobromide is 0.46 Pa at 20°C. However, this measure was not repeatable.
Considering the estimated values of vapour pressure of 2-aminoethanol (35.6 Pa at 20.0°C) and 2-aminoethanol hydrobromide (non-salt form) (5.26 .10-6 Pa at 20.0°C) obtained with EPIsuite software (reports summary are in the attached document), we can assess that the 2-AMINOETHANOL HYDROBROMIDE owns a low vapour pressure.
