Description of key information
Additional information
A summary of the physicochemical study results for Chlorendic Anhydride is tabulated below;
| Endpoint | Result |
| Physical appearance | White solid |
| Melting point | 235 - 239°C |
| Boiling point | 266.5 - 322°C |
| Relative density | 1.76 |
| Particle size distibution | 0.1% w/w < 10 µm |
| Vapour pressure | 2.68 E-03 Pa at 25°C |
| Partition coefficient | Log Pow = -1.59 (for Chlorendic acid) |
| Water solubility | 0.499 g/l for Chlorendic acid < 2.5 E-03 g/l for Chlorendic anhydride |
| Surface tension | 72.0 mN/m (90% saturated solution) Due to rapid hydrolysis result for chlorendic acid. |
| Flash point | Flash point is a property relevant to liquids and low melting point solids and so is waived in accordance with Section 2 of annex XI of the REACH regulation |
| Auto flammability | Explosivity study not undertaken as Chlorendic Anhydride is used as a flame retardant. |
| Flammability | Explosivity study not undertaken as Chlorendic Anhydride is used as a flame retardant. |
| Explosiveness | Explosivity study not undertaken as Chlorendic Anhydride is used as a flame retardant. |
| Oxidising properties | In accordance with column 2 of REACH Annex VII, the study does not need to be conducted because on the basis of its chemical structure, the substance is incapable of reacting exothermically with combustible materials. |
| Stability in organic solvents | In accordance with column 1 of REACH Annex IX, the study is only required if stability of the substance is considered to be critical. |
| Dissociation constant | Study not undertaken as Chlorendic Anhydride readily hydrolyses. |
| Viscosity | In accordance with section 2 of REACH Annex XI, the viscosity does not need to be performed as the substance is a solid. |
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.
