Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 297-474-6 | CAS number: 93572-43-1 A complex combination of hydrocarbons obtained by refining of crude oil. It consists predominantly of aromatics, naphthenics and paraffinics and produces a finished oil with a viscosity of 120 SUS at 100°F (23cSt at 40°C).

Any other information on results incl. tables
Three runs on the sample were conducted. There was initially substantial reduction (equivalent to 3°C temperature change) of estimated VP on prolonged pumping after Run 1 but this was reduced to the equivalent of 0.65°C change between Runs 2 and 3. The latter runs provided values at room temperature of 1.882 and 1.563 x 10-4 Pascals, yielding a mean value of Vp (298.15K) = 1.723 x 10-4 Pascals. The condensation rates onto the pan observed in Run 3 increased with temperature more rapidly than the mass difference indicating an increasing efficiency of condensation and thus precluding the use of the condensation data to produce a satisfactory VP relation. The final values of rate of condensation were however equivalent in pressure regime to the mass differences assuming a rough equality between the numerical magnitudes of temperature and molar mass.
Applicant's summary and conclusion
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.
