Latent heat of evaporation of sample = 48.3 kJ mol-1.

Conclusions:
A boiling point of 167 °C was obtained for 2-(2-methylpropoxy)ethanol at an atmospheric pressure of 101.325 kPa.
Executive summary:

An experiment was conducted in line with OECD Guideline 103 (Boiling Point), without deviation, to measure the boiling point of 2-(2-methylpropoxy)ethanol. The ebulliometer technique and the Clapeyron-Clausius equation were employed to calculate the latent heat of evaporation of the liquid as well as the boiling point temperature at an atmospheric pressure of 101.325 kPa. To conclude, 2-(2-methylpropoxy)ethanol was found to have a boiling point and latent heat of evaporation of 167 °C and 48.3 kJ mol -1, respectively.

Description of key information

In an experiment to determine the boiling point of 2-(2-methylpropoxy)ethanol, a final value of 167 °C was concluded at an atmospheric pressure of 101.325 kPa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
167 °C

Additional information

An experiment was undertaken according to OECD Guideline 103 (Boiling Point), without deviation, to ascertain a key value for boiling point. The endpoint conclusion has been assigned a Klimisch score of 1 (reliable without restriction) and is concluded to be legitimate for regulatory use.
