key study
Study period:
May 30, 2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
no
GLP compliance:
no
Type of method:
differential scanning calorimetry
Key result
Melting / freezing pt.:
-70 °C
Conclusions:
The onset of melting for 2-ethylhexanoic acid, compound with 2-aminoethanol (1:1) was determined to be -70 °C. The complete melting of the substance, termed peak temperature, occurred at -62 °C.
Executive summary:

An experiment was performed according to OECD Guideline 102 (Melting point / Melting Range) using the differential scanning calorimetry (DSC) method to determine the melting point of 2-ethylhexanoic acid, compound with 2-aminoethanol (1:1). An onset temperature and peak temperature of -70 and -62 °C, respectively, was determined for the registered substance. Onset of melting was regarded as the key value to satisfy the endpoint for melting point.
