Methyl isobutyl ketone (MIBK, 4-methylpentan-2-one) is an organic compound with the condensed chemical formula (CH 3) 2 CHCH 2 C(O)CH 3. This ketone is a colourless liquid that is used as a solvent for gums, resins, paints, varnishes, lacquers, and nitrocellulose.
Mesityl oxide is used as a solvent and in the production of methyl isobutyl ketone by hydrogenation: [5] Further hydrogenation gives 4-methyl-2-pentanol (methyl isobutyl carbinol). Dimedone is another established use of mesityl oxide.

Ketones give positive results in Brady's test, the reaction with 2,4-dinitrophenylhydrazine to give the corresponding hydrazone. Ketones may be distinguished from aldehydes by giving a negative result with Tollens' reagent or with Fehling's solution. Methyl ketones give positive results for the iodoform test. [7]
4-Methyl-2-pentanol (IUPAC name: 4-methylpentan-2-ol) or methyl isobutyl carbinol (MIBC) is an organic chemical compound used primarily as a frother in mineral flotation and in the production of lubricant oil additives such as Zinc dithiophosphate. [4]
Increasing bacterial outbreaks and newer strains of Microbes and Pathogen invading our lives daily, there is an increasing need to Test these microbes. Mutating Bacteria poses a higher risk to humans more than ever and thus MIC Test is important to ensure we are one step ahead of them.
Twin sisters in Wisconsin are proving there is no one more supportive than a twin, especially when they learn you're having a baby.. Payton Meulemans, 26, recorded the moment she told her twin ...
The epoxide equivalent weight is usually measured first and done by titration. The standard test method is ASTM D1652 though this has been modified by certain states of the USA. [3] The epoxy equivalent weight (EEW) maybe defined as: the number of grams of epoxy resin required to give 1 mole of epoxy groups. [4]
