Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- key study
- Study period:
- Feb - Mar 2005
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Principles of method if other than guideline:
- If the vapour pressure is expected to be so small that the value is below the measurement range of an experimental determination (e.g. the gas satuaration method), then the vapour pressure can also be calculated, using the modified Watson correlation. this method is described by Lyman et al. (1990)
- GLP compliance:
- no
- Type of method:
- other: calculation
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source (i.e. manufacturer or supplier) and lot/batch number of test material: 4G08
- Purity, including information on contaminants, isomers, etc.: approx 95% no further information
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: at room temperature at about 20 °C in dry conditions
- Stability and homogeneity of the test material in the vehicle/solvent under test conditions (e.g. in the exposure medium) and during storage: not stated but assumed stable
- Stability in the medium, i.e. sensitivity of the test material to hydrolysis and/or photolysis: not stated but assumed stable
- Solubility and stability of the test material in the solvent/vehicle and the exposure medium: no solvent/ vehicle used
- Reactivity of the test material with the incubation material used (e.g. plastic ware): no reactivity assumed
TREATMENT OF TEST MATERIAL PRIOR TO TESTING
no treatment
FORM AS APPLIED IN THE TEST (if different from that of starting material)
same as received - Key result
- Temp.:
- 25 °C
- Vapour pressure:
- < 0 Pa
- Key result
- Transition / decomposition:
- yes
- Transition temp.:
- ca. 285 °C
- Conclusions:
- The vapour pressure of the main component of MG-60 was estimated to be 1.35 * 10E-22 Pa at 25 °C.
Reference
The boiling point of the main component of MG-60 was calculated to be aporximately 715 °C using Meissners method.
The vapour pressure of the main component of MG-60 was estimated to be 1.35 * 10E-22 Pa at 25 °C.
Description of key information
The vapour pressure was calculated, a threshold value is used for CSA
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 25 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
