Ethylene dimethacrylate

Boiling point

Link to relevant study record(s)

Reference

Endpoint:

boiling point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

09.02.2006 - 09.02.2006

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Remarks:

OECD 104, consistent with GLP. Boiling point was taken from measured vapour pressure curve.

Qualifier:

according to guideline

Guideline:

other: OECD Guideline 104 (Vapour Pressure Curve) adopted by the Council on 27 July1995

Deviations:

no

Principles of method if other than guideline:

The vapour pressure is determined by measuring the boiling temperature of the substance at various specified pressures between roughly 10 to
approx. 10³ hPa. The apparatus consists of a tube with a boiling section (by electrical heating) in the lower part, a cooler in the middle part, and an
outlet to a pressure regulation system in the upper part. The thermometer is placed in the vapour above the surface of the liquid. The temperature of the vapour is measured as a function of the pressure.

GLP compliance:

no

Remarks:

consistent with GLP

Type of method:

dynamic method

Specific details on test material used for the study:

- Name of test material (as cited in study report): Ethyleneglycol dimethacrylate
- Substance type: organic
- Physical state: liquid

Key result

Boiling pt.:

275 °C

Atm. press.:

965.8 hPa

Remarks on result:

other: Determined according to OECD guideline 104. Boiling point was taken from measured vapour pressure curve.

A portion of Ethyleneglycol dimethacrylate was given in a glass apparatus. The measurements started at the initial pressure of 15.2 hPa and at thermodynamic equilibrium. The pressure was increased stepwise.

	Vapour pressure [hPa]	Boiling point [°C]	Inverse temperature x 1000 [K-1]
	15.2	121.6	2.5332
	26.7	131.6	2.4707
	50.2	145.3	2.3898
	103.6	163.5	2.2902

	965.8	275.2	1.8237

Conclusions:

The boiling point of Ethyleneglycol dimethacrylate was determined according to OECD guideline 104 [adopted on 27 July 1995] and EU test
method A.4 [Directive 92/69/EEC, Official Journal L 383 A 1992] with the dynamic method.
The boiling point was: 275 °C at 965.8 hPa. The boiling point was taken from measured vapour pressure curve.

Executive summary:

The boiling point of Ethyleneglycol dimethacrylate was determined according to OECD guideline 104 [adopted on 27 July 1995] and EU test method A.4 [Directive 92/69/EEC, Official Journal L 383 A 1992] with the dynamic method. The boiling point was: 275 °C at 965.8 hPa. The boiling point was taken from measured vapour pressure curve.
