[edit] Lindlar

I am trying to figure out the meaning of the collection of chemical formulas at Lindlar catalyst. It is very, very difficult to depict the nature of a heterogeneous catalyst, but the thing you posted is not a Lindlar catalyst but a set of ingredients. Possibly you might choose to recast these formulas into some sort of in-line equation that describes how the catalyst is prepared, but the collection of individual formulas are barely relevant to the nature of catalyst itself. The catalyst does not contain lead acetate, for example - it is derived from lead acetate (or other lead(II) sources). Just a suggestion. Best wishes,--Smokefoot 16:02, 19 May 2007 (UTC)

Actually I got the three compounds directly from Vollhardt, Organic Chemistry - a standard textbook as you might know. But actually I don't know any better way of picturing it and I don't know enough about the preparation technique that I could go any further and make a better picture (and I don't know how it would look like). Although the "+" indicates that these are individual substances mixed together. So would it be best do delete the picture again? Thanks, --hroest 18:32, 20 May 2007 (UTC)
