presence of acetone and dimethylamine (uremia). Detection of a small number of Salmonella enterica bacteria is achieved due to a change in the surface stress on the silicon nitride cantilever surface in situ upon binding of bacteria. Scanning electron micrographs indicate that less than 25 adsorbed...

terminator is a non-polyalkyleneamine which will react with the polyalkyleneamine mixture to form a tertiary amine. So, for example, a terminator compound may be added during transamination to stop the reaction. Useful terminators include secondary amines (e.g., dimethylamine, diethylamine, etc.)....
The hydrolysis can be performed in various solvents, including water; liquid ammonia; alcohols such as methanol, ethanol, isopropanol, and t-butanol; amines such as methylamine, dimethylamine, ethylamine and the like; and hydroxy amines such as ethanolamine. However, it is much preferred to simply...
Higher molecular weight polyamines, such as higher molecular weight ethyleneamines (i.e., amines containing 4 or more N atoms) may be produced from ethylene dichloride and ammonia. This process, sometimes referred to as the EDC process, produces a complex mixture of various linear, cyclic, and ...
