Talk:Lithium aluminium hydride

IUPAC Name

Isn't the IUPAC name Lithium tetrahydridoaluminate not Lithium aluminium hydride? I'm no expert on nomenclature but I say this because the IUPAC name for NaBH4 is Sodium tetrahydridoborate not Sodium borohydride. APHST (talk) 21:03, 21 January 2009 (UTC)

Melting Point

Wiki page states it 150^oC (decomposition). Looking through some other sources like, [1] [2] [3] as well as Knovel data table, they all list the melting point at 125^oC. I believe the Wiki page has listed an incorrect melting point, and would like to correct it if others agree with me. --Vishnu2011 (talk) 21:29, 23 October 2009 (UTC)

GA Work?

I will try to address some of the critique raised in reviews as far as possible, as I only have limited time. For now I have added references to the "Thermal Decompossition" section as well as the "Thermodynamics" section. I will see if I can dig up refs. for the solubility data. Further I will try and write something about hydrogen storage. Andr (talk) 20:15, 2 May 2010 (UTC)

Status

Added the original discovery ref. to Sclessinger, did a bit of restructuring, starting a section on "Hydrogen storage". Still need to find a few more refs. for solubility data. Andr (talk) 20:14, 4 May 2010 (UTC)

Status II

I can't do more with the article at the moment. Hope that someone else would like to continue improving the article. Is it time to ask for a new nomination as a good article, or should more work be done?? Andr (talk) 20:10, 5 May 2010 (UTC)

Need more references. Maybe they are already in the article and just need to be shifted or copied. If a reference covers the paragraph, it would better stay at its end. Dangling (unreferenced) ends of paragraphs don't look good. Also, if there is enough material on history, it is worth adding a subsection on that. After that, it is worth GA nominating, to receive further comments. Materialscientist (talk) 11:20, 6 May 2010 (UTC)

The article is really excellent, especially for materials apps but its real (and virtually only) use is for organic synthesis. To quote for Ullmann's Encyclopedia of Industrial Chemistry "Bulk lithium aluminum hydride is used almost exclusively for the reduction of organic

functional groups. The principal consumers are the organic chemical, pharmaceutical, and the flavoring and perfumery industries." The content of the article should reflect this reality, to some extent? My suggestions for missing bits:

• mechanism of the main application, the reduction of organic compounds. Kinetics and mechanism (more pertinent than a TGA or XRD to the user group!!)
• comparison with the corresponding borohydrides (how reducing power changes as one progresses through EH_4-x(OR)_x^- for E = Al vs B).
• mechanism for protonolysis/hydrolysis.
• spectroscopic characterization (NMR, IR esp)
• solvation (of the Li+) upon dissolution.
• LiAlD4 is important, but is not mentioned.
• the inorganic section mentions a silly reaction, the prep of NaH, but this is not a real use.
• purification of the gray commercial product.
• The section on hydrogen storage is under "applications" but might be better placed under "research directions" and should definitely not be indicated in the lead, IMHO.
• lacking is a section on the modified hydride reducting agents, again reflecting the fact that the article has somehow been converted into something approaching a materials science essay whereas its real reason for existence is generating C-H bonds. Kinda strange.

I am glad too see the prompt feedback and very constructive critique raised. I agree with the above suggestions, certainly, and I am mostly responsible for the materials science twist given to the article. My background is chemical engineering and research in solid state hydrogen storage partly with respect to LiAlH4. I do not have the organic chemistry background knowledge to improve in the direction outlined above, sorry. Anyway I found a reference from a commercial supplier chemetall with some useful info. I really hope the article will gain some momentum and that it could attract contributors in order to address the above items. Andr (talk) 18:35, 6 May 2010 (UTC)

Yes I do agree. Salik sayyef (talk) 14:16, 22 November 2016 (UTC)

solvent data

why nothing for THF at 50c?
