A complex combination of hydrocarbons produced by the vacuum distillation of the residuum from atmospheric distillation of crude oil. It consists of hydrocarbons having carbon numbers predominantly in the range of C20 through C50 and boiling in the range of approximately 350°C to 600°C (662°F to 1112°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.184.108.40.206 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.
