Description of key information
pKa = 9.38
Key value for chemical safety assessment
Additional information
As other organic salts, sodium levulinate is a strong electrolyte and in water solution it dissociates completely. It is reasonable to assume that Na+ ion does not react with water; while levulinate ion, deriving from levulinc acid, which is a weak acid, in water produces a surplus of hydroxide ions leading to a basic solution.
The pKa was evaluated as to be 9.38.
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.
