Potassium neodecanoate

Melting point / freezing point

Link to relevant study record(s)

Reference

Endpoint:

melting point/freezing point

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

comparable to guideline study with acceptable restrictions

Remarks:

Only one inweight with two heating intervals was conducted instead of at least two independent measurements. Company data: The results, the graphics and the SOPs for DSC and TGA measurements were available instead of a study report with a detailed description (materials, procedure, results, conclusion) of the measurement.

other: TGA

DSC

No observed melting up to 300 °C.

TGA

Phase 1: -0.63 % mass reduction up to 78 °C (Water)

Phase 2: -68.13 % mass reduction up to 528 °C (Disassociation)

Phase 3: -4.93 % mass reduction up to 760 °C (Unidentified)

Conclusions:

Potassium neodecanoate has no melting point up to 300 °C according to a DSC analysis. In a TGA a decomposition range from 78 °C up to 528 °C was recorded.
