This is unique source of information on the chemicals manufactured and imported in Europe. Due to its pyrophoric nature, instability, toxicity, low shelf life and handling problems associated with its reactivity, it has been replaced in the last decade, both at the small-industrial scale and for large-scale reductions by the more convenient related reagent sodium bis (2-methoxyethoxy)aluminium hydride, which exhibits similar reactivity but with higher safety, easier handling and better economics. [H-]. De plus amples informations sur la pratique multilingue de l'ECHA sont disponibles. Structure. Precautionary statements - describe recommended measures to minimise or prevent adverse effects resulting from exposure to a hazardous product or improper storage or handling of a hazardous product. Note the primitive cell may appear less symmetric than the conventional cell representation (see "Structure Type" selector below the 3d structure) More information about the EC Inventory can be found here. The solid is dangerously reactive toward water, releasing gaseous hydrogen (H2). Reactivity can be tuned by replacing hydride groups by alkoxy groups. Molecular structure. Information on applicable regulatory frameworks is also automatically generated and may not be complete or up to date. When heated LAH decomposes in a three-step reaction mechanism:[15][16][17], R1 is usually initiated by the melting of LAH in the temperature range 150–170 °C,[18][19][20] immediately followed by decomposition into solid Li3AlH6, although R1 is known to proceed below the melting point of LiAlH4 as well. Release to the environment of this substance can occur from industrial use: manufacturing of the substance. Hazard statements were adapted to improve readability and may not correspond textually to the hazard statements codes description in the European Union Specific Hazard Statements (EUH) or the. This Directive establishes rules for the safe transport of dangerous goods between EU countries by road, rail, and waterway. The EC or list number is the primary substance identifier used by ECHA. [9], LiAlH4 was first prepared from the reaction between lithium hydride (LiH) and aluminium chloride:[4][5], In addition to this method, the industrial synthesis entails the initial preparation of sodium aluminium hydride from the elements under high pressure and temperature:[10]. It is possible that a harmonisation is introduced through an amendment to the CLP Regulation. Although the compound has been extensively studied with respect to thermal stability , heat capacity , , NMR , , high-pressure melting and polymorphism and microwave spectra , little is known about its crystal structure.
