Description of key information
Bis[C11-14-(branched and linear)-alkyl]aminium nonadecaoxohexatungstate (EC 700-718-0), based upon results from the surrogate substance, has a melting point of less than -80 °C (NOTOX B.V., 2012).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -80 °C
Additional information
Surrogate substance: In an OECD 102 study, conducted according to GLP, the melting temperature of reaction mass of bis(C11-14-alkyl, branched and linear)amine nonadecaoxo hexatungstate (the surrogate substance) was determined initially using differential scanning calorimetry (DSC). Since no crystalisation or melting of the test substance was observed by DSC an additional test, in which a subsample of the test substance was placed overnight in a freezer at -20 degrees Centigrade and -80 degrees Centigrade, was performed. It was observed after storage that the test substance was still a (slightly to highly viscous) liquid in both experiments. According to this it was concluded that the melting temperature of the test substance is less than -80 degrees Centigrade (< 193K) (Notox B.V., 2012).
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).
