- Executive summary:
The test item reaction mass of N-butylphthalimide and N-sec-butylphthalimide and N-propylphthalimide has a boiling point of 302.9 °C at atmospheric pressure (1013 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995).
Reference
During the heating phase a distinct endothermic effect was observed in the temperature range of 120 – 320 °C, which can be assigned to the boiling of the test item.
For the correction of the boiling temperature to standard pressure the test item was assigned to chemical group 2 (e.g. hydrocarbons). A correction value f = 5.15 was thus used for the temperature of 300 °C.
The lowest measured onset temperature is corrected to the standard pressure to be 302.53 °C and the highest onset temperature to be 303.35 °C. As the corrected onset temperatures in both tests deviate by less than 0.5 K from their mean value of 302.94 °C, the test item has a boilingpoint of 302.9 °C.
No further thermal effects were observed up to the test end temperature of 500 °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.
