Er, this page is about Louis Pasteur, not chemical synthesis. Anyone with chemistry knowledge want to have a go at this? -- April

Uhm. I can't agree that all chemical syntheses are a consequence of direct chemical combination. Otherwise, you put yourself in trouble when you synthesize caramel from sugar. All it requires is a carefully controlled heat source. Dwmyers 21:36, 15 Sep 2003 (UTC)


Good point. Also, take for instance the thermal decomposition of Calcium carbonate to Calcium oxide and Carbon dioxide. Another problem with the page is that it claims that a metal chloride reacts with Oxygen to form... that metal chloride again. Doesn't it seem like we aren't getting anywhere?

Does this really need its own page? For the topic at hand, chemical synthesis, the page is quite brief. Not much discussion on the talk page over 7 year span. Relevant content should be merged to subcategories of chemistry. 24.130.82.154 (talk) 06:57, 2 August 2010 (UTC)[reply]

First chemical synthesis of Ingenol

[edit]

I was thinking maybe this is worth a mention? - http://www.scripps.edu/news/press/2013/20130801baran.html
I'm no scientist, but it sounds fairly significant.

Moving unsourced, sophomoric section out of article

[edit]

The following section appears to be scratching of someone in training, who is versed neither in standard academic expectations of essay writing (where one cites one sources) or in WP encyclopedic writing (whose policies demand the same). Here is the section.

SECTION—Other meanings

The other meaning of chemical synthesis is narrow and restricted to a specific kind of chemical reaction, a direct combination reaction, in which two or more reactants combine to form a single product. The general form of a direct combination reaction is:

A + B → AB

where A and B are elements or compounds, and AB is a compound consisting of A and B. Examples of combination reactions include:

2Na + Cl2 → 2NaCl (formation of table salt)
S + O2SO2 (formation of sulfur dioxide)
4Fe + 3O2 → 2Fe2O3 (iron rusting)
CO2 + H2OH2CO3 (carbon dioxide dissolving and reacting with water to form carbonic acid)

4 special synthesis rules:

metal-oxide + H2O → metal(OH)
non-metal-oxide + H2O → oxi-acid
metal-chloride + O2 → metal-chlorate
metal-oxide + CO2 → metal carbonate (CO3)

Please put the part of it that is useful content back in, even if it is only a sentence, after (i) you understand what the original editor was trying to convey, (ii) you determine what part of that originally intended content fits with the scope of this article, (iii) you identify sources that support the usable content, (iv) you re-write that part in good English sentences, and (v) you format and place the good citations with the text.
