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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Reaction product of Crude sludge and Calcium oxide. Crude sludge is the mixture of by-products of petroleum hydrocarbons refining (especially Total petroleum hydrocarbons, Polycyclic aromatic hydrocarbons, acid-refined heavy petroleum distillates). The Crude sludge is neutralised by calcium oxide in the ratio 80:20. The maturing process proceeds under ambient conditions and takes for at least 3 days. Subsequently, the reaction product is processed mechanically.

Description of key information
Method A.16 Relative self-ignition temperature for solids, Council Regulation (EC) No.440/2008, published in O.J. L 142, 2008, was performed.
GLP study.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 270.2 °C
Additional information
The relative self-ignition temperature of test substance was measured.
Principle of test method:
A certain volume of the substance under test is placed in an oven at room temperature; the temperature/time curve relating to conditions in the centre of the sample is recorded while the temperature of the oven is
increased to 400°C or to the melting point if lower, at a rate of 0.5°C/min. For the purpose of this test, the temperature of the oven at which the sample temperature reaches by self-heating is called the self-ignition temperature.
Reaction product of Distillates (petroleum), acid-treated heavy naphthenic and calcium oxide showed relative self-ignition temperature 270.2°C.
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.
