- Conclusions:
- Using a linear heating rate of 10 °C/min the melting point of p-Nitrobenzoic acid, compound with 2,2’,2”-nitrilotriethanol (1:1) was determined to be in the range of 105.4 – 111.2 °C (378.6 – 384.3 K).
- Executive summary:
For the determination of the melting point differential scanning calorimetry method was used. The test was carried out at normal atmospheric pressure. Applying a linear heating rate, the melting point of p-Nitrobenzoic acid, compound with 2,2’,2”-nitrilotriethanol (1:1) was determined to be in the range of 105.4 – 111.2 °C (378.6 – 384.3 K).

Description of key information
The melting point of p-Nitrobenzoic acid, compound with 2,2’,2”-nitrilotriethanol (1:1) was determined in a GLP study using differential scanning calorimetry (Klimisch 1, Toxicoop, 2017).
Applying a linear heating rate, the melting point of p-Nitrobenzoic acid, compound with 2,2’,2”-nitrilotriethanol (1:1) was determined to be in the range of 105.4 – 111.2 °C (378.6 – 384.3 K).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 105.4 °C
Additional information
Melting point range of 105.4 – 111.2 °C (378.6 – 384.3 K).
