Vanadium oxysulphate

Boiling point

Link to relevant study record(s)

Reference

Endpoint:

boiling point

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

study well documented, meets generally accepted scientific principles, acceptable for assessment

Justification for type of information:

Dierct observation from heating
As the substance is impossible to remove from water, the onset of boiling / degradation was linked to the presence of the water

Qualifier:

equivalent or similar to guideline

Guideline:

EU Method A.2 (Boiling Temperature)

Principles of method if other than guideline:

Direct heating of the solution to see if boiling occured. Boiling started at ca 100 C with a colour change suggesting degradation

GLP compliance:

no

Type of method:

other: Direct observation under heating

Specific details on test material used for the study:

Production grade material as solution with ca 36 - 37% actives

Boiling pt.:

ca. 100 °C

Atm. press.:

ca. 1 atm

Decomposition:

yes

Remarks:

Colour change as water started to be removed

Decomp. temp.:

ca. 100 °C

The substance does boil at a temperatures of 100 °C. However, this is attributed to the water in solution and not the actual substance.

The test was performed by direct observation by heating to100 C. Boiling started and colour changes to blue.

Conclusions:

The substance does boil at a temperatures of 100 °C. However, this is attributed to the water in solution and not the actual substance.
The test was performed by direct observation by heating to100 C. Boiling started and colour changes to blue.
