Methyl acetone

Methyl Acetone. Commercial product .a water-white, anhydr liq, consisting of various mixts of acet (45 to 65%), methyl acetate (20 to 30%) and methanol (20 to 40%). Density about 0.83g/cc, boiling range 50 to 70°, flash p near 0°F. Miscible with hydrocarbons, oils and w. Obtained as a by-product in the manuf of acet and methanol from wood distn, representing fractions which cannot be economically sepd. The mixt can be used as such, being an excellent solv and plasticizer for NC and other cellulose esters, such as the acetate. It also dissolves rubber, gums, resins, lacquers, paint and varnish Refs 1) T.H, Durrans, Solvents , Van-Nostrand, NY (1938), 122 2) CondChemDict... [Pg.112]

Comparisons of structurally related hydroxy- and methoxy-substituted cations show that hydroxy is more stabilizing by between 4 and 5 log units. This difference was recognized 20 years ago by Toullec who compared pifas for protonation of the enol of acetophenone and its methyl ether145 (-4.6 and 1.3, respectively) based on a cycle similar to that of Scheme 15, but with the enol replacing the hydrate, and a further cycle relating the enol ether to a corresponding dimethyl acetal and methoxycarbocation.146 Toullec concluded, understandably but incorrectly, that there was an error in the pA a of the ketone (over which there had been controversy at the time).147,148 In a related study, Amyes and Jencks noted a difference of 105-fold in reactivity in the nucleophilic reaction with water of protonated and O-methylated acetone and concluded that the protonated acetone lacked a full covalent bond to... [Pg.53]

Straight-chain alkanes also efficiently react with ozone in Magic Acid at —78°C in SO2CIF solution. Ethane gave protonated acetaldehyde as the major reaction product together with some acetylium ion (Scheme 5.62). Reaction of methane, however, is rather complex and involves oxidative oligocondensation to terf-butyl cation, which reacts with ozone to give methylated acetone (Scheme 5.63). [Pg.670]

METHYL ACETONE (78-93-3) Forms explosive mixture with air (flash point 30°F/—1°C also reported at 16°F/—9°C). Violent reaction with strong oxidizers, aldehydes, nitric acid, perchloric acid, potassium tert-butoxide, oleum. Incompatible with inorganic acids, aliphatic amines, ammonia, caustics, isocyanates, pyridines, chlorosulfonic acid. Able to form unstable peroxides in storage, or on contact with 2-propanol or hydrogen peroxide. Attacks some plastics. Flow or agitation of substance may generate electrostatic charges due to low conductivity. [Pg.759]

So, for instance, acetic acid is carbonic acid with one oxygen substituted by methyl, acetone has two oxygens replaced by methyl radicals, aldehyde is the same except one of the two methyls is replaced by hydrogen, and alcohol is aldehyde with a third oxygen atom of carbonic acid replaced by hydrogen.
