- Executive summary:
Huber-Lohr (2021) is a GLP-compliant study following OECD guideline 103 and EU method A2. It is reliable without restrictions and can be used as a key study for this endpoint. The boiling point was measured by DSC measurements and by capillary tubes in a metal block. The test item had a wide boiling range of 25 – 315 °C according to EuropeanCommission Regulation (EC) No. 440/2008, A.2. as well as OECD 103 (1995) at atmospheric pressure (1013.3 hPa). The test item boiled only partially. The test item boiled under decomposition.

No. | Set point / | Heating rate / K/min | End | Remarks |
1 | 25 | 10 | 300 | Starting at approx. 62 °C: The test item was still a pale-yellow clear liquid, occasionally, the formation of tiny bubbles rising to the surface was observed. Starting at approx. 86 °C: Unsteady formation of larger bubbles. Starting at approx. 95 °C: Steady formation of larger bubbles accompanied by evaporation of approx. 80 % of the liquid test item. Starting at approx. 130 °C: The test item turned into a yellow-brown liquid and the formation of tiny bubbles was observed. Starting at approx. 180 °C: Further discolouration into a red-brown liquid. Starting at approx. 215 °C: Further discolouration into a dark-brown liquid and the formation of tiny bubbles could be observed. Starting at approx. 285 °C: Further discolouration into a black-brown liquid and the formation of unsteady violent formation of bubbles. Approx. 290 - 300 °C: No further change (test item not fully evaporated). |
