Nickel-Modified TS-1 Catalyzed the Ammoximation of Methyl Ethyl Ketone

Methyl ethyl ketone peroxide

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...

Thermal Hazard Analysis of Methyl Ethyl Ketone Peroxide

In the past forty years in Japan and Taiwan, many thermal explosions have been caused by methyl ethyl ketone peroxide (MEKPO) under the influence of external fire and others. Thermograms of commercialized MEKPO dimers were first screened by Differential Scanning Calorimetry (DSC) to determine the heat of decomposition and exothermic onset temperature. Thermal runaway phenomena were then thoroug...

The Reaction Mechanism of Acetaldehyde Ammoximation to Its Oxime in the TS-1/H2O2 System

A qualitative analysis for the ammoximation of acetaldehyde to its oxime in the TS-1(Titanium Silicalite-1)/H2O2 system was investigated using an in situ infrared spectrometer (ReactIR15). NH3 is first oxidized to NH2OH by TS-1/H2O2; then, CH3CH=NOH forms after NH2OH reacts with CH3CHO. That means the intermediate of this reaction is NH2OH instead of CH3CH=NH. Experiments have been conducted to...

Ternary Liquid – Liquid Equilibria: Hexamethyldisiloxane – Dimethyl Sulfoxide – Methyl Ethyl Ketone (-Diethyl Ketone)

New experimental solubilities and tie line data for ternary mixtures containing two completely miscible binaries and one nonmiscible binary as part of a program to determine the thermodynamic properties of a series of ternary and binary systems with HMDS [1–3] are given. Hexamethyldisiloxane 99.5%, NMR grade, 2-butanone 99.5%, HPLC grade (MEK), 3-pentanone 99% (DEK) and dimethyl sulfoxide 99.9%...
