Ketones methyl amyl ketone

Methyl Amyl Ketone. Methyl amyl ketone [110-43-0] (MAK) (2-heptanone) is a colorless Hquid with a faint fmity (banana) odor. It is found in oil of cloves and cinnamon-bark oil, and is manufactured by the condensation of acetone and butyraldehyde (158). Other preparations are known (159-162). 

NIOSH Methods 1300 and 1301 (NIOSH 1984) describe the determination of common ketones in air. The compounds evaluated in the study include acetone, methyl propyl ketone, methyl isobutyl ketone, methyl n-butyl ketone, diisobutyl ketone, cyclohexanone, ethyl butyl ketone, methyl amyl ketone, ethyl amyl ketone, mesityl oxide, and camphor [76-22-2], The analysis involves adsorption... 

On the other hand, Gavrilova and Gonikberg opened the furan ring with hydrogen, without the use of catalysts.213 The reaction is carried out at high temperature (350-375°) and at a pressure between 240 and 750 atmospheres, in the absence of a solvent. The following products are obtained from 2-methylfuran acetone, methyl ethyl ketone, methyl butyl ketone, methyl amyl ketone, acetophenone, methylpropylcarbinol, w-pentane, and water. The authors suggest that these products are formed by a free radical mechanism.

The physical properties of finish removers vary considerably due to the diverse uses and requirements of the removers. Finish removers can be grouped by the principal ingredient of the formula, method of appHcation, method of removal, chemical base, viscosity, or hazardous classification. Except for method of apphcation, a paint remover formulation usually has one aspect of each group, by which it can be used for one or more appHcations. A Hst of the most common organic solvents used in finish removers has been compiled (3). Many are mentioned throughout this article others include ethyl lactate [97-64-3] propylene carbonate [108-32-7] furfural alcohol [98-01-1/, dimethyl formamide [68-12-2] tetrahydrofuran [109-99-9] methyl amyl ketone [110-43-0] dipropylene glycol methyl ether [34590-94-8] and Exxate 600, a trade name of Exxon Chemicals. 

The remaining (8%) //-butyraldehyde production of the United States goes into (in decreasing order) poly(vinyl butyral), 2-ethyIhexanal, trimethylolpropane, methyl amyl ketone, and butyric acid. 

Methyl amyl ketone, derived from the crossed aldol condensation of -butyraldehyde and acetone, is used predominandy as a high soHds coatings solvent. It is also employed as a replacement for the very toxic 2-ethoxyethyl acetate [111 -15-9J.

According to the submitters, methyl amyl ketone (800 g.) and ammonia (600 cc.) have been converted to 2-aminoheptane, b.p. 139-141°, in exactly the same manner, in 50-55 per cent yields. A slightly modified procedure was used in the preparation of w-heptylamine and furfurylamine. Heptaldehyde (320 g.) was dissolved in 500 cc. of methanol, and 150 cc. of liquid ammonia was added the reduction was conducted as above. w-Heptyla-mine, b.p. 57-58°/23 mm., was obtained in yields of 53-63 per cent. Freshly distilled furfural (290 g.) was dissolved in 500 cc. of methanol, 150 cc. of liquid ammonia was introduced, and the reduction carried out as usual. The product was removed, filtered, and fractionated directly. Furfurylamine, b.p. 144-146°, was obtained in 50 per cent yield. 

Half-blocked Dllsocyanates. The half-blocked diisocyanates were prepared using conventional methods (2) by adding dropwlse, over a period of one hour, 1 mole of alcohol to 1 mole of diisocyanate and 100 mg dibutyl tin dilaurate in methyl amyl ketone under an inert atmosphere. After the addition of the alcohol, the reaction was heated at 60-80°C for 2 hours. For half-blocked diisocyanates prepared from tertiary alcohols, the heating period was replaced with room temperature stirring for 24-36 hours to prevent undesirable side reactions.

In a 3-I. round-bottom flask, fitted with an efficient Liebig condenser (100 X 1 cm.), 228 g. (2 moles) of methyl -amyl ketone (Org. Syn. 7, 60) is dissolved in a mixture of 600 cc. of 95 per cent alcohol and 200 cc. of water. One hundred and thirty grams (5.4 moles) of sodium in the form of wire is gradually added through the condenser. During the addition of the sodium the flask is cooled with running water (Note 1) so that the reaction does not become unduly violent (Note 2).
