A complex residuum from atmospheric distillation of crude oil. It consists of hydrocarbons having carbon numbers predominantly greater than C11 and boiling above approximately 200°C (392°F). This stream is likely to contain 5 wt.% or more of 4- to 6-membered condensed ring aromatic hydrocarbons.
In accordance with REACH Chapter R.7A Endpoint Specific Guidance, specifically R.18.104.22.168 Information Requirements on Dissociation Constant, if the substance cannot dissociate due to a lack of relevant functional groups, the dissociation constant is not required. As petroleum hydrocarbons do not contain functional groups subject to dissociation, data for this endpoint is not needed.
