no

Qualifier:

according to guideline

Guideline:

OECD Guideline 102 (Melting point / Melting Range)

Melting / freezing pt.:

< -70.9 °C

Melting / freezing pt.:

< 202.3 K

Freezing temperature:

The determination of the freezing temperature with thermocouples showed no heat effect from which freezing could be deduced. Therefore, the phase transformation was determined visually.

In a preliminary test, 2ml test item 2 -(2'-Vinyloxyethoxy)ethyl acrylate was stored for 24 hours at -20 deg C. The test item was still a colourless liquid after storage.

In the main test, about 6ml of the test item placed in a small test tube was cooled down from room temperature to -70.9 deg C using a dry ice/isopropanole mixture. Below a temperature of about -44 deg C, the test item became more viscous, but remained liquid down to a temperature of -70.9 deg C. No solidification could be observed.

In conclusion, the freezing point of 2 -(2'-Vinyloxyethoxy)ethyl acrylate was determined to be < - 70.9°C which is equal to < 202.3K.

Conclusions:

During this study the freezing point/melting range of 2-(2'-Vinyloxyethoxy)ethyl acrylate has been determined. In conclusion the freezing point of 2-(2'-Vinyloxyethoxy)ethyl acrylate was determined to be < - 70.9 deg C which is equal to < 202.3 K).

Executive summary:

During this study the freezing point range of 2 -(2'-Vinyloxyethoxy)ethyl acrylate was determined to be < - 70.9 deg C which is equal to <202.3 K, this was determined according to the OECD guideline 102 and Method A1 of EEC Directive 92/69/EEC.
