LXIV.—The pungent principles of ginger. Part I. A new ketone, zingerone (4-hydroxy-3-methoxyphenylethyl methyl ketone) occurring in ginger

Methyl ethyl ketone and methyl isobutyl ketone not carcinogenic.

Methyl Ethyl Ketone and Methyl Isobutyl Ketone Not Carcinogenic The April 22, 1993, issue of Environmental Health Perspectives contained a commentary by Legator and Strawn entitled "Public Health Policies Regarding Hazardous Waste Sites and Cigarette Smoking: An Argument by Analogy." Although the article does not include any discussion of either methyl ethyl ketone (MEK) or methyl isobutyl keto...

Methyl ethyl ketone peroxide

Bis[4-(3-amino­phen­oxy)phen­yl] ketone

In the mol-ecule of the title compound, C(25)H(20)N(2)O(3), the dihedral angles formed by adjacent benzene rings are 66.75 (8), 48.37 (8) and 71.43 (9)°. In the crystal structure, centrosymmetrically related mol-ecules are linked into dimers by inter-molecular N-H⋯O hydrogen bonds.

Methyl Ketone Metabolism in Hydrocarbon-utilizing Mycobacteria.

Lukins, H. B. (University of Texas, Austin) and J. W. Foster. Methyl ketone metabolism in hydrocarbon-utilizing mycobacteria. J. Bacteriol. 85: 1074-1087. 1963.-Species of Mycobacterium especially M. smegmatis 422, produced the homologous methyl ketones during the oxidation of propane, n-butane, n-pentane, or n-hexane. A carrier-trapping experiment demonstrated the formation of 2-undecanone, as...

Radical mechanisms of methyl vinyl ketone oligomerization

This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract It is now accepted that one of the important pathways of Secondary Organic Aerosol (SOA) formation occurs through aqueous phase chemistry in the atmosphere. However , the liquid phase chemical mechanisms leading to ma...
