Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 265-181-2 | CAS number: 64742-78-5 A complex combination of hydrocarbons obtained by treating an atmospheric tower residuum with hydrogen in the presence of a catalyst under conditions primarily to remove organic sulfur compounds. It consists of hydrocarbons having carbon numbers predominantly greater than C20 and boiling above approximately 350°C (662°F). This stream is likely to contain 5 wt. % or more of 4- to 6-membered condensed ring aromatic hydrocarbons.

840 to 1100 Kg/m³ at 15°C
Key value for chemical safety assessment
Additional information
The density of heavy fuel oil components ranges from 840 to 1100 Kg/m³ at 15°C (CONCAWE 2010a).
A density value of 950 to 1010 kg/m³ reported at 15 °C was determined in a reliable study (CONCAWE, 1998) conducted according to ISO 3675 Hydrometer method or ISO 12185 Oscillating U-tube method. Although the experimental result was not conducted by a GLP study, it is still comparable to a guideline study with minor restrictions only. The result is adequate for assessment and suitable for key study.
Three of the studies (Mackay & Zargoski 1982, EETD 1988.009, ESD 1990.010) have reported 0.97 to 0.98 g/cm3at 20°C in a secondary source (Environment Canada database) but no further information is available. A density value of c.a. 0.95 g/cm3 is reported from a chemical handbook (TPHCWG 1998) but no measured temperature is reported.
Studies (various HPV 2004.002-6) have also recorded a specific gravity value of c.a. 0.85 to c.a. 1.1 in the HPV dossier. The original reference was not available for review and no further information is available.
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.
