  2. Acetone - Wikipedia

    en.wikipedia.org/wiki/Acetone

    A variety of organic reactions employ acetone as a polar, aprotic solvent, e.g. the Jones oxidation. Because acetone is cheap, volatile, and dissolves or decomposes with most laboratory chemicals, an acetone rinse is the standard technique to remove solid residues from laboratory glassware before a final wash. [66]

  3. 2,2-Dimethoxypropane - Wikipedia

    en.wikipedia.org/wiki/2,2-Dimethoxypropane

    DMP is used as a water scavenger in water-sensitive reactions. Upon acid-catalyzed reaction, DMP reacts quantitatively with water to form acetone and methanol. [2] This property can be used to accurately determine the amount of water in a sample, alternatively to the Karl Fischer method. [3] DMP is specifically used to prepare acetonides: [4] [5]

  4. Cooling bath - Wikipedia

    en.wikipedia.org/wiki/Cooling_bath

    Cooling baths are generally one of two types: (a) a cold fluid (particularly liquid nitrogen, water, or even air) — but most commonly the term refers to (b) a mixture of 3 components: (1) a cooling agent (such as dry ice or ice); (2) a liquid "carrier" (such as liquid water, ethylene glycol, acetone, etc.), which transfers heat between the ...

  5. Acetone azine - Wikipedia

    en.wikipedia.org/wiki/Acetone_azine

    It can also be produced from acetone (2 eq.), ammonia (2 eq.) and hydrogen peroxide (1 eq.). [4] The first step is the formation of acetone imine, Me 2 C=NH; this is then oxidized by hydrogen peroxide through a complex mechanism to give 3,3-dimethyloxaziridine, which reacts with a further molecule of ammonia to produce acetone hydrazone.

  6. Ketene - Wikipedia

    en.wikipedia.org/wiki/Ketene

    With acetone, ketene reacts to give isopropenyl acetate. [1] A variety of hydroxylic compounds can add as nucleophiles, forming either enol or ester products. As examples, a water molecule easily adds to ketene to give 1,1-dihydroxyethene and acetic anhydride is produced by the reaction of acetic acid with ketene.

  7. Water-reactive substances - Wikipedia

    en.wikipedia.org/wiki/Water-reactive_substances

    Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .

    Acetone is a chemical used to remove nail polish from your nails or as a household cleaner. It also occurs naturally in your body, facilitating ketosis. Uses and Benefits of Acetone

  9. Cyanohydrin reaction - Wikipedia

    en.wikipedia.org/wiki/Cyanohydrin_reaction

    In organic chemistry, a cyanohydrin reaction is an organic reaction in which an aldehyde (−CH=O) or ketone (>C=O) reacts with a cyanide anion (N≡C −) or a nitrile (−C≡N) to form a cyanohydrin (>C(OH)C≡N).
