Applicant's summary and conclusion
- Executive summary:
Aluminium nitrate-9-hydrate is an inorganic salt and consist of aluminium cations [Al(3+)] nitrate anions [NO3(-)] and water (H2O) as hydrate or solvent.
Aluminium nitrate is manufactured as an aqueous solution with more than 90% of the quantity manufactured as a solution containing about 65% water and less than 10% of the quantity manufactured as the nonahydrate with about 43,2% water content. The high water content of both the solution and the nonahydrate can also explain the non flammable properties of the substance. At no point during the manufacturing does the iron trinitrate exist as the water free option, only in solution or as the nonahydrate salt.
Aluminiumnitrate-9-hydrate does not contain carbon (C), hydrocarbon (CH), organic nitro (R2CNO2) ammonium (NH4) amino (R2NH; RNH2) or other groups associated with flammable properties when liked to nitrate(NO3-). Aluminium cations [Al(3+)] are not associated with flammable properties as they can not be oxidized to a higher oxidization stage.
Aluminiumnitrate-9-hydrate was also tested for oxidizing properties. Test results showed that the substance cannot be assigned to the hazard class oxidizing solids according regulation (EG) No. 1272/2008 (CLP-/GHS-regulation) and the substance not to classify as oxidizing according regulation (EG)440/2008.
Furthermore, a DTA (differential thermal analysis) does not show any exothermic decomposition reaction in the range between 30-500°C (see attachment DTA Aluminiumnitrate). Melting occurs in its own hydrate water at about 78°C and dehydration and decomposition in the range of 200 – 270°C and 340-360°C both as endothermic reaction.
This demonstrates that no flammable reaction took place nor decomposition products have been formed in an exothermic reaction.
Our own practical experience over a long period of manufacturing of this substance also supports the facts summarized here. No incidents with flammability or decompositions reaction are known from manufacturing, handling or from customer reports.
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.
