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

Study period:

2016

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

OECD Guideline 102 (Melting point / Melting Range)

Type of method:

differential scanning calorimetry

Key result

Melting / freezing pt.:

-5.1 °C

Atm. press.:

101.3 kPa

Results

The sample shows endothermic melting peaks in the -25 to 5 °C region (Fig. 1 and Table 1). The

lower peak around -25 °C indicates melting of a part of the sample. The macroscopic state of the

substance is still solid.

Table 1: melting point test

Measurement Onset Peak Endset

°C       °C       °C

#1 -5,3       -0,1       3,2

#2 -4,8        0,3       3,8

The mean onset is selected as giving the best value of the start of the melting range. The difference

between the lower onset value and the higher peak value is used to estimate the width of the melting

range.

Conclusions

The melting point of N,N-Dimethylnonanamide is -5.1 ± 5 °C.

Conclusions:

The melting point of N,N-Dimethylnonanamide is -5.1 ± 5 °C (determined by DSC).

Description of key information

The melting point of N,N-Dimethylnonanamide was determined according to OECD Guideline 102 by differential scanning calorimetry.
