The boiling point of Resin acids and Rosin acids, maleated, potassium salts was tested by DSC and according to OECD TG 103.
Reaction and/or decomposition of the test material was observed during DSC experiments at temperatures of >300°C (> 573K). Boiling of the test material
was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test material has no boiling temperature.
Reference
Preliminary Test
Starting at 425°C, the weight of the sample decreased significantly. At 431°C, the sample weight had decreased by 25%. After the experiment, a black
residue remained in the sample container (original colour: dark brown). The change of the colour indicated reaction and/or decomposition of the test material.
Main Study
In Experiment 1 during cooling, no effects were observed which were due to crystallization of the test material. During heating, a large endothermic peak was observed between 25°C and 225°C directly followed by a small endothermic effect between 225°C and 275°C. Based on sponsor’s information, the first endothermic effect was due to evaporation of volatile components (i.e. water). The cause of the second endothermic was unknown. After the experiment, a dark brown residue remained in the sample container.
To investigate the endothermic peak between 25°C and 225°C, a repeated heating cycle was applied in Experiment 2. During cooling and during the second heating, no effects were observed between 25°C and 225°C. This confirmed that evaporation of volatile components was the reason for the
endothermic effect observed between 25°C and 225°C. Endothermic effects were observed starting at 300°C due to reaction and/or decomposition of the test material. After the experiment, a darker brown (compared to the original test material) residue remained in the sample container.
Description of key information
The boiling point of Resin acids and Rosin acids, maleated, potassium salts was tested by differential scanning calorimetry (DSC).
Decomposition of the test material was observed at temperatures of >300°C (> 573K). Boiling of the test material was not observed below the temperature at which reaction and/or decomposition started. Based on this it was not possible to determine a boiling point for the test material.
Key value for chemical safety assessment
Additional information
A GLP-compliant study, conducted according to OECD Guideline 103 (differential scanning calorimetry) was provided for Resin acids and Rosin acids, maleated, potassium salts (H4R Consortium, 2018).
