Editing Butanone (section)

== Applications ==
===Solvent===
Butanone is an effective and common solvent<ref name="TurnerMcCreery">{{Cite book| last = Turner| first = Charles F.|author2=McCreery, Joseph W.| title = The Chemistry of Fire and Hazardous Materials| publisher = Allyn and Bacon, Inc.| year = 1981| location = Boston, Massachusetts| pages = 118| isbn = 0-205-06912-6}}</ref> and is used in processes involving [[natural gum|gum]]s, [[resin]]s, [[cellulose acetate]] and [[nitrocellulose]] coatings and in vinyl films.<ref name="Apps p101">{{Cite book| last = Apps| first = E. A.| title = Printing Ink Technology| publisher = Leonard Hill <nowiki>[Books]</nowiki> Limited| year = 1958|location = London| pages = [https://archive.org/details/printinginktechn00apps/page/101 101]| url =https://archive.org/details/printinginktechn00apps| url-access = registration}}</ref> For this reason it finds use in the manufacture of plastics, textiles, in the production of [[paraffin wax]], and in household products such as [[lacquer]], [[varnish]]es, paint remover, a denaturing agent for [[denatured alcohol]], [[adhesive|glues]], and as a cleaning agent. It is a prime component of plumbers' priming fluid, used to clean PVC materials. It has similar solvent properties to [[acetone]] but boils at a higher temperature and has a significantly slower evaporation rate.<ref name="Fairhall">{{Cite book| last = Fairhall| first = Lawrence T.| title = Industrial Toxicology| publisher = The Williams and Wilkins Company| year = 1957| location = Baltimore| pages = 172–173}}</ref> Unlike acetone, it forms an [[azeotrope]] with water,<ref name="Langes">''Lange's Handbook of Chemistry'', 10th ed. pp1496-1505</ref><ref name="crc">''CRC Handbook of Chemistry and Physics'', 44th ed. pp 2143-2184</ref> making it useful for azeotropic distillation of moisture in certain applications. Butanone is also used in [[dry erase marker]]s as the solvent of the erasable dye.

The hydroxylamine derivative of butanone is [[methylethyl ketone oxime]] (MEKO), which also find use in paints and varnishes as an anti-skinning agent.

===Plastic welding=== <!-- courtesy note per WP:RSECT: [[Polystyrene cement]] links here -->
As butanone dissolves [[polystyrene]] and many other plastics, it is sold as "model cement" for use in connecting parts of [[scale model]] kits.  Though often considered an [[adhesive]], it is functioning as a [[plastic welding|welding]] agent in this context.

===Other uses===
Butanone is the [[Precursor (chemistry)|precursor]] to [[methyl ethyl ketone peroxide]], which is a catalyst for some [[polymerization]] reactions such as crosslinking of unsaturated polyester resins. [[Dimethylglyoxime]] can be prepared from butanone first by reaction with [[alkyl nitrites|ethyl nitrite]] to give [[diacetyl monoxime]] followed by conversion to the dioxime:<ref>{{OrgSynth | author = Semon, W.

In the [[peroxide process]] on producing [[hydrazine]], the starting chemical ammonia is bonded to butanone, oxidized by hydrogen peroxide, bonded to another ammonia molecule.

In the final step of the process, hydrolysis produces the desired product, hydrazine, and regenerates the butanone.
