Study Results - Individual
To determine the boiling behaviour (two independent single measurements), the test item was heated up to 400 °C with a heating rate of 10 K/min. For the measurement a partially capsulated crucible, typical for boiling point measurements, was used.
Individual reported results are shown below.
286 °C (from first measurement)
287 °C (from second measurement)
From 286 °C the test item shows a boiling and/or thermal decomposition with evaporation of the decomposition components. The diagram shows a second endothermic effect with a beginning at ca. 183 °C. It can be recognized as melting of the test item.
The DSC measurements were confirmed by means of TGA measurements under the same measuring conditions. The start of the area of boiling temperatures is defined by using the on-set temperature.
Final Result
The test item p-Anisic acid shows a boiling and/or thermal decomposition earliest at ca. 286 °C (at 1011 mbar; mean value from repeat determination; 1st heating run).
Description of key information
The test item p-Anisic acid shows a boiling and/or thermal decomposition earliest at ca. 286 °C (OECD 103, DSC method).
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 286 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
