ECHA has no public registered data on the types of manufacture using this substance. If no EU harmonised classification and labelling exists and the substance was not registered under REACH, information derived from classification and labelling (C&L) notifications to ECHA under CLP Regulation is displayed under this section. The substance identifiers displayed in the InfoCard are the best available substance name, EC number, CAS number and/or the molecular and structural formulas. The solid is dangerously reactive toward water, releasing gaseous hydrogen (H2). CopyCopied, InChI=1S/Li.H/q+1;-1 The EC Number is the numerical identifier for substances in the EC Inventory. 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. ECHA maintains the C&L Inventory, but does not review or verify the accuracy of the information. The Directive adds limit values for 27 new chemical agents, and amends 6 existing ones established by earlier directives. The ‘Hazard classification’ and labelling section uses the signal word, pictogram(s) and hazard statements of the substance under the harmonised classification and labelling (CLH) as its primary source of information. Harmonisation is based on the substance’s physical, toxicological and eco-toxicological hazard assessment. A substance identified primarily by an EC or list number may be linked with more than one CAS number, or with CAS numbers that have been deleted. Sorption to aerosols (25 Dec C)[AEROWIN v1.00]: Vapor pressure (liquid/subcooled): 7.91E-011 Pa (5.93E-013 mm Hg) Log Koa (Koawin est ): -0.771 Kp (particle/gas partition coef. Le règlement REACH vise à renforcer la protection de la santé humaine et de l’environnement contre les risques que peuvent engendrer les produits chimiques. LiBH4]∞, a structure which consists of polymeric ribbons and contains μ4-hydrogen atoms. Introduction. Le règlement CLP a pour objet d’assurer que les dangers que présentent les substances chimiques soient clairement communiqués aux travailleurs et aux consommateurs de l’Union européenne grâce à la classification et à l’étiquetage des produits chimiques. [13], LiAlH4 contains 10.6 wt% hydrogen, thereby making LAH a potential hydrogen storage medium for future fuel cell-powered vehicles. Classification Codes. This substance has not been registered under the REACH Regulation, therefore as yet ECHA has not received any data about this substance from registration dossiers. At high pressures (>2.2 GPa) a phase transition may occur to give β-LAH. Release to the environment of this substance can occur from industrial use: manufacturing of the substance. Substances for which classification and labelling data have been notified to ECHA by manufacturers or importers. Note the primitive cell may appear less symmetric than the conventional cell representation (see "Structure Type" selector below the 3d structure) Some substance identifiers may have been claimed confidential, or may not have been provided, and therefore not be displayed. The information is aggregated from the data coming from REACH substance registrations provided by industry. Molecular structure. Lithium aluminium hydride, commonly abbreviated to LAH, is an inorganic compound with the chemical formula LiAlH4. 3.2, Table A), Directive 2008/68/EC, last amended by Regulation 2019/1243/EU, 25 July 2019, EU. The ‘Substance identity’ section is calculated from substance identification information from all ECHA databases. ECHA has no public registered data indicating whether or into which articles the substance might have been processed. Lithium aluminohydride. Devient sombre lors d'exposition à la lumière, Se décompose au-dessous du point d'ébullition à. [Li+] Aged, air-exposed samples often appear white because they have absorbed enough moisture to generate a mixture of the white compounds lithium hydroxide and aluminium hydroxide. This information has not been reviewed or verified by ECHA, and may change without prior notice. The use information is displayed per substance life cycle stage (consumer use, in articles, by professional workers (widespread uses), in formulation or re-packing, at industrial sites or in manufacturing). Aldehydes and ketones[31] can also be reduced to alcohols by LAH, but this is usually done using milder reagents such as NaBH4; α, β-unsaturated ketones are reduced to allylic alcohols. The CLP Regulation makes sure that the hazards presented by chemicals are clearly communicated to workers and consumers in the European Union. [38]It was observed that the LiAlH4 reduces the double bond in the N-allylamides. And the electronic structure of the hydride anion H – is: 1s 2, which is also very stable. Value might be unreliable.

ECHA has no public registered data indicating whether or in which chemical products the substance might be used. The quality and correctness of the information submitted to ECHA remains the responsibility of the data submitter. listes des produits chimiques soumis au règlement PIC. LAH is a colorless solid, but commercial samples are usually gray due to contamination. The quality and correctness of the information submitted to ECHA remains the responsibility of the data submitter. Substances listed in the EINECS, ELINCS, or NLP inventories. Dangerous Goods List (RID, Chap. Examples include recommended measures on fire-fighting, transport and recycling and disposal. Le 6LiD est utilisé dans les bombes H, pour former le combustible de fusion. Likewise the per substance indication of harmonised C&L, Seveso directive, or notified C&L regulatory context will be made available as soon as possible. It applies the European Agreements on the international transport of dangerous goods by road (ADR) and inland waterways (ADN), and the Regulations concerning the international carriage of dangerous goods by rail (RID). It is a grey solid. When information is available in all sources, the first two are displayed as a priority. Release to the environment of this substance can occur from industrial use: as an intermediate step in further manufacturing of another substance (use of intermediates).
