Description of key information
Self-ignition temperature of Pitch, coal tar, high-temp., < 1% 4- to 5-membered condensed ring aromatic hydrocarbons [EC no. 701-305-8](CTPhtht): > 560 °C at 101 kPa (in analogy to pitch, coal tar, high-temp. [CAS No. 65996-93-2])Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 560 °C
Additional information
The substance Pitch, coal tar, high-temp., < 1% 4- to 5-membered condensed ring aromatic hydrocarbons [CTPhtht] is used as surrogate. CTPhtht is produced from the precursor pitch, coal tar, high-temp. as residue in a distillation that further removes volatile substances and leaves higher membered condensed ring aromatic hydrocarbons. As consequence, the self-ignition temperature of CTPhtht will be at least the same or rather be increased. For characterisation of the autoflammability of CTPhtht, the autoflammability of pitch, coal tar, high-temp. will be used.
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.
