Butanone is the 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 ethyl nitrite to give diacetyl monoxime followed by conversion to the dioxime: [ 15 ]
Water testing being conducted at a treatment facility in Broken Bow, Oklahoma. Water testing is a broad description for various procedures used to analyze water quality. Millions of water quality tests are carried out daily to fulfill regulatory requirements and to maintain safety. [1] Testing may be performed to evaluate:
Methyl vinyl ketone (MVK, IUPAC name: butenone) is the organic compound with the formula CH 3 C(O)CH=CH 2.It is a reactive compound classified as an enone, in fact the simplest example thereof.

A positive test is signalled by the formation of a yellow, orange or red precipitate of the dinitrophenylhydrazone. Aromatic carbonyls give red precipitates whereas aliphatic carbonyls give more yellow color. [2] The reaction between DNPH and a generic ketone to form a hydrazone is shown below:
3-Methyl-2-butanone (methyl isopropyl ketone, MIPK) is a ketone and solvent of minor importance. It is comparable to MEK ( Methyl ethyl ketone ), but has a lower solvency and is more expensive. [ 2 ]
The threshold value is the concentration at which an aroma or taste can be detected (air, water and fat). The recognition threshold or arousal threshold of olfactory neurons is the concentration at which you can identify an odor (air, water and fat). The odour activity value is the concentration divided by the threshold.
Acetoin is a neutral, four-carbon molecule used as an external energy store by a number of fermentative bacteria. It is produced by the decarboxylation of alpha-acetolactate, a common precursor in the biosynthesis of branched-chain amino acids.
