Description of key information
In accordance with Column 2 adaptation statement of REACH Annex VII, information requirement section 7.3, this study does not need to be conducted since the substance decomposes before boiling. Due to the instability (due to the varied chemical composition) of pyrolysis liquids, they do not exhibit a true boiling curve.
Key value for chemical safety assessment
Additional information
Data from literature indicates that the high oxygen content of fast pyrolysis bio oil is indicative of the presence of many highly polar groups leading to high viscosities and boiling points as well as relatively poor chemical stability (Bridgwater et al. 1999). Due to their chemical composition, bio-oils show a very wide range of boiling temperature. In addition to water and volatile organic components, biomass pyrolysis oils contain substantial amounts of nonvolatile materials such as sugars and oligomeric phenolics. Moreover, the slow heating of the oils during distillation results in polymerization of some reactive components. Consequently, the oils start boiling below 100 °C but the distillation stops at 250 -280 °C, leaving 35-50% of the starting material as residue (Czernik and Bridgwater 2004).
