Reference
Preliminary test:
Two steps were registered with maxima at 383 °C resp. 484°C. A total mass loss of 99.5 % at the final temperature could be observed (mass change in the range until 410°C: 86.4 %; mass change in the range from 410 to 600°C: 13.1 %). No significant mass loss occurred due to purging. The course of the thermogravimetric curve suggests decomposition of the test item.
After cooling the residue was brown-black inside the crucible.
Main test:
The DSC measurements were performed twice in the temperature range from 20 - 440°C resp. from 20 - 450°C. A sharp endothermic peak indicating a melting point could be observed (peak maximum: 173°C / 172 °C; extrapolated onset temperature: 170 °C / 169.87 °C; rounded mean of both determinations: 170°C). Upon further heating the DSC-curve showed one more wide endothermic peak (peak maximum: 388°C/ 388°C; extrapolated onset temperature: 359.60 °C / 359.88 °C) followed by an exothermic peak (peak maximum: 409°C / 409 °C). Due to the fact that the thermogravimetric measurement did not show a complete mass loss in that temperature range, no normal boiling point could be observed. The endothermic peak changed into an exothermic peak. This suggests a possible boiling of the main compound with simultaneous decomposition. Reweighing after the measurement showed that the sample had lost 71.6 % / 70.6 % of its mass. The residue looked brown-black on the bottom of the crucible.
Boiling temperature: no boiling point; boiling of the main compound with simultaneous decomposition
Description of key information
Ethyltriphenylphosphonium iodide has no clear boiling point. At 360°C possible boiling with simultaneous decomposition was observed.
Key value for chemical safety assessment
Additional information
No clear boiling point detected. The boiling point of Ethyltriphenylphosphonium iodide was determined in a GLP study according to OECD Guideline 103 (27 July 1995) and EU Method A.2 (30 May, 2008) using differential scanning calorimetry in two independent experiments. The DSC-curve showed a wide endothermic peak (peak maximum: 388°C / 388°C; extrapolated onset temperature: 359.60 °C / 359.88 °C) followed by an exothermic peak (peak maximum: 409°C / 409 °C). Due to the fact that the thermogravimetric measurement did not show a complete mass loss in that temperature range, no normal boiling point could be observed. The endothermic peak changed into an exothermic peak. This suggests a possible boiling of the main compound with simultaneous decomposition.
