- Key result
- Melting / freezing pt.:
- >= 347.1 - <= 364.6 °C
Applicant's summary and conclusion
- Conclusions:
- The melting point was determined via DSC (differential scanning calorimetry). The melting point under decomposition referring to the pre-test was determined under these circum-stances as the endothermic event given in a range from:
347.10°C (620.25K) – 364.60°C (637.75 K)
This value represents the mean of four independent determinations.
. No observations were made which might cause doubts on the validity of the study outcome. Therefore, the result of the study is considered valid. - Executive summary:
Title of Study: Determination of the melting point of Potassium isobutyrate according to OECD 102 resp.EU A.1
Findings and Results:
The melting point was determined via DSC (differential scanning calorimetry)
The melting point under decomposition referring to the pre-test was determined under these circumstances as the endothermic event given in a range from:
347.10°C (620.25K) – 364.60°C (637.75 K)
