Specific details on test material used for the study:

Name of test material (as cited in study report): Methylmorpholine
Analytical purity: 99.9 % (Aldrich)

Key result

Boiling pt.:

114.25 °C

Atm. press.:

999.9 hPa

The regression of the results leads with a
mean deviation of 0.15 % to the following equation (range of measurements 17.58 - 114.25 °C):
ln (p/bar) = 9.4919 - 3150.39 / (217.56 + t/°C)

Conclusions:

The boiling point of the test substance was determined to be 114.25 °C at 999.9 hPa in a non GLP vapour pressure determination according to OECD Guideline 104.

Description of key information

The boiling point of the test substance was determined to be 114.25 °C at 999.9 hPa in a non GLP vapour pressure determination according to OECD Guideline 104 (BASF AG, 2000).

Key value for chemical safety assessment

Boiling point at 101 325 Pa:

114 °C

Additional information

The vapour pressure was determined by measuring the boiling temperature of the substance at various specified pressures (dynamic method; also recommended for the determination of the boiling temperature in OECD TG 103, boiling point). Test was performed under nitrogen atmosphere.
