Editing Butanone (section)

===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.
