nitrile gloves and hydrolysis of water

the preparation of nitriles - chemguide- nitrile gloves and hydrolysis of water ,Making nitriles from amides. Nitriles can be made by dehydrating amides. Amides are dehydrated by heating a solid mixture of the amide and phosphorus(V) oxide, P 4 O 10. Water is removed from the amide group to leave a nitrile group, -CN.

an introduction to nitriles - chemguide

Nitriles contain the -CN group, and used to be known as cyanides. Some simple nitriles. The smallest organic nitrile is ethanenitrile, CH 3 CN, (old name: methyl cyanide or acetonitrile - and sometimes now called ethanonitrile). Hydrogen cyanide, HCN, doesn't usually count as organic, even though it contains a carbon atom.
