The Condensation of Benzaldehyde with Methyl Ethyl Ketone by Aqueous Sodium Hydroxide

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...

Biosorption of Uranium (VI) from Aqueous Solution by Pretreated Aspergillus niger Using Sodium Hydroxide

The removal of uranium and any other heavy metals from wastewater might be achieved via several chemical or physical treatment techniques. Biosorption process has been considered as a potential alternative way to remove contaminants from industrial effluents. Moreover the surface of biosorbent was characterized by SEM. The biosorption characteristics of uranium (VI) on pretreated A...

A simple automated system for the routine production of 99mTc by methyl-ethyl-ketone extraction.

A relatively simple, automated system for the rapid, efficient and safe routine production of 9'l"'TcM from "Mo03 by the methyl-ethyl-ketone (MEK) extraction technique is described. The 4 phases of the extraction process bubbling of air, phase separation, drawing off of 9'lTc in MEK, and evaporation to dryness, are controlled by an automatic timer, suction-pressure pump and solenoid switches. T...
