isoteniscope

Key result

Temp.:

20 °C

Vapour pressure:

0.6 hPa

Conclusions:

2-Ethylhexanoic acid, compound with 2-aminoethanol (1:1) has a vapour pressure of 0.60 hPa at 20 °C.

Executive summary:

2-Ethylhexanoic acid, compound with 2-aminoethanol (1:1) was tested according to ASTM D2879 - 97 (Standard Test Method for Vapor Pressure-Temperature Relationship and Initial Decomposition Temperature of Liquids by Isoteniscope) in order to determine vapour pressure. A minor deviation was reported in which a digital electronic pressure gauge was used for pressure measurement in place of a mercury manometer, as stipulated in ASTM D2879 - 97. However, this is not believed to have affected the final result. Vapour pressure was concluded to be 0.60 hPa at 20 °C.
