- Executive summary:
Guidelines: The study procedure used for the determination of the boiling temperature of HATCOL 3331 was based on the following guidelines: European Economic Community (EEC), EEC-Directive 92/69 EEC, Part A, Methods for the determination of physico-chemical properties, A.2 "Boiling temperature", EEC Publication No. L383, December 1992. Organization for Economic Co-operation and Development (OECD), OECD guidelines for testing of Chemicals, guideline no. 103: "Boiling point", July 27, 1995.
Experiments: Both the test substance and an inert reference were heated in a differential scanning calorimeter (DSC). The difference between the heal flow to the sample and the heat flow to the reference was recorded. Four experiments were performed. The results of all experiments were combined for the conclusion.
Conclusion: Boiling of the test substance was not observed. Only some small heat effects were observed, which probably indicate a combination of small endothermic (above about 117°C, 390 K; possibly caused byevaporation of small amounts of volatile impurities) and exothermic (above about 175°C, 448 K; possibly caused by reaction or decomposition of the test substance) effects. Visual indication for reaction or decomposition, i.e. change of the colour of the test substance, was observed on heating the test substance up to 400°C (673 K), but was not observed on heating up to 300°C (573 K).

Experiments:
First experiment (25°C - 400°C): The curve showed no endothermic effect that can be ascribed to boiling. Only some small effects were observed that probably are combinations of endothermic effects which are possibly caused by evaporation of small amounts of test substance (possibly volatile impurities) and small exothermic effects which are probably caused by reaction or decomposition of the test substance. After the experiment the sample had a slightly yellow colour (the test substance was originally colourless). The sample had lost 8% of its mass during the experiment.
Second experiment (25°C - 200°C): No endothermic effect that can be ascribed to boiling was observed. Possibly a very small endothermic effect started at about 117°C. This effect may be caused by evaporation of a small amount of volatile impurities. Above about 175°C the effect changed to slightly exothermic. The exothermic effect may be caused by reaction or decomposition. However, the appearance of the sample had not changed during the experiment. No significant mass change was observed.
Third experiment (25°C - 300°C): No endothermic effect that can be ascribed to boiling was observed. Possibly a very small endothermic effect started at about 118°C. This effect may be caused by evaporation of a smallamount ofvolatile impurities. Above about 176°C this effect changed to a slightly exothermic effect. The small exothermic effect may be caused by reaction or decomposition. The appearance of the sample had not changed during the experiment. The sample had lost 1% ofits mass.
Fourth experiment (25°C - 400°C): The characteristics of the recorded curve are equal to those of the previously measured curves. After the experiment the sample had a slightly yellow colour. The sample had lost 11 % of its mass during the experiment.
Conclusion: Boiling of the test substance was not observed. Only some small heat effects were observed, which probably indicate a combination of small endothermic (above about 117°C, 390 K; possibly caused by evaporation of small amounts of volatile impurities) and exothermic (aboveabout 175°C, 448 K; possibly caused by reactionor decomposition of the test substance) effects. Visual indication for reaction or decomposition, i.e. change of the colour of the test substance, was observed on heating the test substance up to 400°C (673 K), but was not observed on heating up to 300°C (573 K).
Experiments:
First experiment (25°C - 395°C): The curve showed an exothermic effect at temperatures above about 180°C. A larger exothermic effect was observed above 360°C. The exothermic effects are probably caused by reaction or decomposition of the test substance. After the experiment the sample had a light yellow colour (the test substance was originally colourless). The change of the colour also indicates that the sample had reacted or decomposed. The sample had lost 8% of its mass.
Second experiment (25°C - 300°C): No endothermic effect that can be ascribed to boiling was observed. Above about 177°C an exothermic effect was observed, which Is probably caused by reaction or decomposition. However, the visual appearance of the test substance had not changed during the experiment. The sample had lost 1 % of its mass.
Third experiment (25°C - 395°C): No endothermic effect that can be ascribed to boiling was observed. Above about 170°C an exothermic effect was observed. A larger exothermic effect was observed above about 360°C. The exothermic effects are probably caused by reaction or decomposition. After the experiment the sample had a light yellow colour (the test substance was originally colourless). The change of the colour also indicates that the sample had reacted or decomposed. The sample had lost 6% of its mass.
Experiments:
First experiment (25°C - 232°C): The curve showed an exothermic effect at temperatures above about 180°C. This effect is possibly caused by reaction or decomposition of the test substance. However, after the experiment the visual appearance of the sample was unchanged (the test substance was originally colourless). No significant mass loss was observed.
Second experiment (25°C - 400°C): No endothermic effect that can be ascribed to boiling was observed. Possibly a very small endothermic effect started at about 125°C. This effect may be caused by evaporation of a small amount of volatile impurities. Above about 182°C the effect changed to slightly exothermic. The exothermic effect may be caused by reaction or decomposition. Above 355°C a larger exothermic effect was observed. This effect is probably caused by reaction or decomposition of the test substance. After the experiment the sample had a light yellow colour (original: colourless), which also indicates that the sample had reacted or decomposed. The sample had lost 8% of its mass.
Third experiment (25°C - 375°C): No endothermic effect that can be ascribed to boiling was observed. Possibly a very small endothermic effect started at about 125°C. This effect may be caused by evaporation of a small amount of volatile impurities. Above about 185°C the effect changed to slightly exothermic. The exothermic effect may be caused by reaction or decomposition. Above 350°C a larger exothermic effect was observed. This effect is probably caused by reaction or decomposition ofthe test substance. However, contrary to the observation after the second experiment, now the appearance of the sample had not changed. The sample had lost 4% of its mass.
Results
Preliminary test
From 375°C upwards the weight of the sample decreased significantly. At 428°C the sample weight had decreased by 25%.
After the experiment a small brown residue remained in the sample container.
Main study
During cooling as well as during heating, no effects were observed which were caused by crystallisation and/or melting. Between 350°C and 475°C an endothermic peak was observed which was due to boiling of the test substance. The extrapolated onset was determined to be 417.15°C.
During the second experiment the endothermic boiling peak was observed with an extrapolated onset of 417.44°C.
Additionally, the test substance was stored
overnight in a -20°C freezer in order to determine if crystallization
occurs. After storage the test substance had not been crystallized. From
this it was concluded that the melting temperature is < -20°C
(253K).
Description of key information
Key value determined by experiment in accordance with OECD guideline 103 and EU test standard A2.
Boiling point could not be determined due to decomposition of the test substance.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 417 °C
