Description of key information

At a barometric pressure of 755 mm Hg the autoignition temperature was found to be 280°C.

Key value for chemical safety assessment

Additional information

The autoignition temperature of the test substance was determined in accordance with ASTM test guideline E659 -06. At a barometric pressure of 755 mm Hg the autoignition temperature was found to be 280°C.

In addition, the autoignition temperature of Gas oil (polymer-derived), thermal cracked, full range was determined in accordance with ASTM test guideline E659 -06. At a barometric pressure of 751 mm Hg the autoignition temperature was found to be 275°C.The study was conducted on Gas oil (polymer-derived), thermal cracked, full range, from which the registered substance is derived via steam stripping, and which is compositionally similar to the registered substance. Gas oil (polymer-derived), thermal-cracked, full-range and Thermal cracking oil from blends of rubber, fuel oils and paraffin waxes, steam-stripped are two very closely related substances. They consist of hydrocarbons having carbon numbers predominantly in the same range (C7 to C32) and boil over a very similar temperature range. The oils contain a relatively large proportion of substituted aromatic hydrocarbons (between 62 and 70%), particularly 1-ring aromatic hydrocarbons. Detailed analytical characterisation shows that the oils have a significant number of individual components in common. Both oils are produced by thermal cracking of the same range of hydrocarbon feedstocks at a temperature of 450-500°C. Thermal cracking oil from blends of rubber, fuel oils and paraffin waxes, steam-stripped differs from Gas oil (polymer-derived), thermal-cracked, full-range in that it has been through a steam-stripping process that removes a proportion of the lower boiling components. In addition to their composition and similar manufacturing process, testing has revealed that the two oils have very similar physico-chemical parameters, especially their solubility in water which is in the region of 3 mg/l suggesting that the two substances might be expected to behave similarly in biological and environmental aqueous environments.
