Talk:Green chemistry

message: I have added a cat. called green chemistry. I think that we need to make it clear that green chemistry is not the same as enviromental chemistry.
Environmental chemistry is the chemistry of how something behaves in the enviroment it might be something such as carboxylic acids in rainwater, the nitrogen cycle or Pu in soil.
Green chemistry is chemistry (normally synthetic chemistry) which has been designed to have as small an impact on the enviroment. Examples might include the use of solventless reactions and supercritial CO2.

replies: text: Totally agree that it's not the same thing, and we need to make it clear. I've done some work to the Environmental chemistry article, which hopefully makes to point clear enough. Though obviously feel free to expand the point if you think it's needed. Also hope you don't mind- I fixed the link in your post above (to stop it red linking). --Petros471 12:56, 29 January 2006 (UTC)

message: This might be a leading citation: Chem. Commun., 2001, 2462 - 2463, DOI: 10.1039/b106584j
"Exploiting modularity in template-controlled synthesis: a new linear template to direct reactivity within discrete hydrogen-bonded molecular assemblies in the solid state", Giannis S. Papaefstathiou, Alex J. Kipp and Leonard R. MacGillivray. Or maybe their reference 6. Or ref. 11.  
HOWEVER!!  There are thousands and thousands of template-directed bond forming reactions in the solid state initiated by light, X-rays, gamma-rays, etc.  Many of them form unique products in high yield.  SO WHAT?  Why is this example in the Green Chemistry article?  This reaction requires a Rayonet reactor operating at 300 nm.  You waste a lot of electricity doing that.  How about finding an example that does not occur in solution or that does occur with sunlight or other natural source rather than with artificial UV.  This example is symmetrical (A=A + A=A --> photodimer); how about a reaction that can be performed selectively in the solid state over the solution phase (A=B + C=D --> one of many products)? 
Maybe I just don't get it. AdderUser 12:29, 11 December 2006 (UTC)

message: A large observational database of many different atmospheric constituents from a host of platforms is available. This was created as part of ESA Envisat and NASA Aura validation. It is of general use. Do you think it should be added to the article text? Dlary
:It sounds like that is relevant to the field of environmental chemistry, which is quite different from green chemistry. DMacks 07:39, 5 February 2007 (UTC)

message: In de section on "Organometallic chemicals" two abriviations are used (ALD and CVD), which both link to disambugation pages. Is anyone capable of puting the correct links, as I just wanted to know what the abriviations in this context are standing for. Thanks a lot. T.vanschaik (talk) 20:40, 12 February 2011 (UTC)

message: How is this green chemistry?  It might be, but there is no explanation as to why it is, and the only reference is to the paper about the process.  Is there an independent source?  As this is an encyclopedia, the examples should illuminate the subject. Chemical Engineer (talk) 15:44, 12 September 2014 (UTC)

message: But NaCl is not a problem as a product, and in any case NaOCl is produced from NaCl, and NaCl could be recycled so where is the advantage?  Where does the H2O2 come from? You cannot just use one reaction, but have to consider the whole process and life cycle.Chemical Engineer (talk) 19:20, 14 September 2014 (UTC)
replies: text: Helpful comments. I dont buy that NaCl is not a problem. I guess one can needs to define the system boundaries in any process, and that can be rather vague (where did the H2O2 come from for example).  As a chemical shorthand, one can rank greenness by the non-protoduction of things other than water. Perfect?  No, but a start.  The green-chem area is filled with baloney and hippie thinking, but the issue for us editors is to describe the area as best we can. --Smokefoot (talk) 20:24, 14 September 2014 (UTC)
thread_title:  Hydrazine 

message: Currently, the article's introduction ends with a collection of statements about who came up with green chemistry (the term and the concept) first, almost like a series of competing endorsements. I propose to rewrite this paragraph -- using a few scholarly secondary sources (some already cited in this article), I think we can present a much clearer and more accurate picture than we have now. Would it be overdoing it to add a separate 'History' section?

replies: text: It would be great if you could re-write the lede. It is pretty awful, and too focused on personalities vs the actual topic.  I think that there are some textbooks on the topic that might be good guides.--Smokefoot (talk) 16:26, 5 September 2015 (UTC)
replies: text:  Thanks for the encouragement! I've rewritten the offending paragraph. Exactly what kind of introduction works best is not totally obvious to me at this point. I'm holding off on the History section for now. What we have is definitely a work in progress.  -- Akokai (talk) 06:38, 6 September 2015 (UTC)
