Melamine use as non-protein nitrogen (NPN) for cattle was described in a 1958 patent. In 1978, however, a study concluded that melamine "may not be an acceptable non-protein N source for ruminants" because its hydrolysis in cattle is slower and less complete than other nitrogen sources such as cottonseed meal and urea.
Manganese is a chemical element with symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in minerals in combination with iron. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels.
by Gottlieb, Kotlyar, and Nudelman. By compiling the chemical shifts of a large number of contaminants commonly encountered in synthetic chemistry, the publica tion has become an essential reference, allowing for easy identification of known impurities in a variety of deuterated organic solvents.
Cyclohexanone (also known as Oxocyclohexane, pimelic ketone, cyclohexyl ketone, and CYC) is a clear oily liquid that has a colourless to light yellow tinge and a pungent odour. It has the formula C6H10O and is slightly soluble in water and is completely miscible with common solvents. It occurs naturally in crude oils and is also produced synthetically, in large quantities, as it is a key intermediate in the production of nylon.
