WebThe amide is converted to the nitrile by careful heating in the presence of the dehydrating agent phosphorus pentoxide. Amides can be reduced to amines by catalytic hydrogenation or by reaction with lithium aluminum hydride. Amides can also react with hypohalites to form primary amines with one less carbon atom. WebHow P4O10 is formed? Phosphorus pentoxide (P4O10) is synthesized by the burning of phosphorus in an excess amount of oxygen. It's a white-colored, crystalline powder and used vastly as a dehydrating agent. P4O10 is obtained when water is eliminated from H3PO4 and undergoes hydrolysis when comes in contact with water.
