Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.6., Water Solubility, Council Regulation (EC) No.440/2008, published in O.J. L 142, 2008
GLP study
Key value for chemical safety assessment
- Water solubility:
- 4.8 g/L
- at the temperature of:
- 20 °C
Additional information
Water solubility test was performed for the test substance. Flask method was used.
The test substance contains a mixture of several compounds which some of them are not soluble in water.
The concentration of the substance in the aqueous solution was determined by evaporating of known volume of the saturated solution.
Cations were additionally analysed by Inductively Coupled Plasma (ICP) - optical emission spectroscopy.
Concentration of TOC (Total Organic Carbon) was determined too.
The water solubility of the test substance is 4.80 g/L at the temperature of 20°C.
Standard uncertainty is 0.14 g/L. Standard uncertainty is equal to one standard deviation.
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.
