Ketone

<p>Ketones are produced on massive scales in industry as solvents, polymer precursors, and pharmaceuticals. In terms of scale, the most important ketones are <a href="http://en.wikipedia.org/wiki/Acetone" title="Acetone">acetone</a>, <a href="http://en.wikipedia.org/wiki/Methylethyl_ketone" title="Methylethyl ketone" class="mw-redirect">methylethyl ketone</a>, and <a href="http://en.wikipedia.org/wiki/Cyclohexanone" title="Cyclohexanone">cyclohexanone</a>.<sup id="cite_ref-Ullmann_9-0" class="reference"><a href="http://en.wikipedia.org/wiki/Ketone#cite_note-Ullmann-9">[9]</a></sup> They are also common in biochemistry, but less so than in organic chemistry in general. The combustion of hydrocarbons is an uncontrolled oxidation process that gives ketones as well as many other types of compounds.</p>
