Reverse osmotic concentration of aqueous 2-butanone (methyl ethyl ketone), tetrahydrofuran and ethyl acetate solutions.

Methyl ethyl ketone peroxide

Atmospheric mixing ratios of methyl ethyl ketone (2-butanone) in tropical, boreal, temperate and marine environments

Methyl ethyl ketone (MEK) enters the atmosphere following direct emission from vegetation and anthropogenic activities, as well as being produced by the gas-phase oxidation of volatile organic compounds (VOCs) such as nbutane. This study presents the first overview of ambient MEK measurements at six different locations, characteristic of forested, urban and marine environments. In order to unde...

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...

Ethyl 2-(2-methyl-1H-benzimidazol-1-yl)acetate

A new benzimidazole compound, C(12)H(14)N(2)O(2), has been synthesized by the reaction of 2-methyl-1H-benzimidazole and ethyl 2-bromo-acetate. In the crystal structure, weak inter-molecular C-H⋯N hydrogen bonds link the mol-ecules into chains. π⋯π Contacts (centroid⋯centroid distance = 3.713 Å) are observed. A C-H⋯π inter-action is also present. The N-C-C-O torsion angle is 178.4 (2)°.

Isobaric vapor-Liquid Equilibrium of Ethyl-Acetate+ 2-Propanol and Ethyl Acetate+ Ethanol Mixtures at 84.8 kPa

Accurate vapor-liquid equilibrium data have been obtained for ethyl acetate + 2-propanol and ethyl acetate + ethanol mixtures at 84.8 kPa, and the results are discussed thermodynamically. The vapor-liquid equilibrium data are correlated with redlich-Kister, Margules, Van-Laar and Ortega, equations the parameters and standard deviation of which are calculated and reported. The best correlati...
