Conclusions:

Using MPBPWIN v1.43 the boiling point of the test item was calculated to be 158.32 °C. The substance is within the applicability domain of the model. Thus the estimation is considered to be accurate.

Executive summary:

The boiling point was calculated using MPBVP v1.43 as part of EPISuite v4.11 from US Environmental Protection Agency.Using MPBPWIN v1.43 the boiling point of the test item was calculated to be 158.32 °C.

The adequacy of a prediction depends on the following conditions:

 

a) the (Q)SAR model is scientifically valid: the scientific validity is established according to the OECD principles for (Q)SAR validation;

b) the (Q)SAR model is applicable to the query chemical: a (Q)SAR is applicable if the query chemical falls within the defined applicability domain of the model;

c) the (Q)SAR result is reliable: a valid (Q)SAR that is applied to a chemical falling within its applicability domain provides a reliable result;

d) the (Q)SAR model is relevant for the regulatory purpose.

 

For assessment and justification of these 4 requirements the QMRF and QPRF files were developed and attached to this study record.

Main Test:

For the main study the device was heated to 145 °C. The capillaries containing the test item were placed into the apparatus and the temperature was raised at 1 °C/min heating rate until the boiling temperature was reached. Three tests were carried out. The boiling point of 2-(allyloxy)ethanol was determined to be 159.5 ± 0.29 °C (95 % confidence interval) i.e. 432.7 K.

Atmospheric pressure, kPa (at the measuring)	Boiling point, °C (at standard atmospheric pressure)
101.2	159.6
101.2	159.4
101.2	159.6
Mean:	159.5
RSD (CV %):	0.1
Conf.int. (95 %)	0.29

Conclusions:

The boiling point of the test item was determined to be 159.5 °C at a pressure of 101.325 kPa.

Executive summary:

The boiling point of the test item was determined according to OECD test guideline 103 and Regulation (EU) No. 440/2008, Method A.2. For this purpose, the Siwoloboff method was used. The test item was heated from 145 °C at 1 °C/min heating rate. The moment of boiling was determined automatically. The experiment was performed in triplicate. The atmospheric pressure was recorded before the measurement and automatically corrected to the standard atmospheric pressure. The mean boiling point of the test item was determined to be 159.5 °C at a pressure of 101.325 kPa.
