Conclusions:

The melting point of N,N'-[(methylimino)bis(trimethylene)]bis(stearamide) was determined to be in a range of 70 to 89 °C, using differential scanning calorimetry.

Executive summary:

A study on differential scanning calorimetry according to OECD Guideline 103 (27 July 1995) was conducted with N,N′-[(methylimino)bis-(trimethlene)]bis-(stearamide).

The heating phase covered a range from room temperature to 500 °C. During the heating phase endothermic effects were observed in two temperature ranges. The first endothermic effect can be assigned to the melting of the test item. The test item showed a second endothermic signal in the temperature range of approx. 350 -470 °C.

No further thermal effects were observed up to the test end temperature of 500 °C.

Melting of N,N′-[(methylimino)bis-(trimethlene)]bis-(stearamide) was observed in a range of 70 to 89 °C.
