Nitrylamid is an inorganic chemical compound and the simplest representative of the substance group of nitramines. It's structural isomer to Hyposalpetrigen acid.

Production and representation

Nitrylamid can be obtained from potassium cyanate with ethanolic hydrochloric acid, ethyl nitrate, ammonia, potassium hydroxide and sulfuric acid by means of a multi-stage reaction starting with the last step is the hydrolysis of Dikaliumnitrocarbamat. It was first shown by J. Thiele and A. Lachman beginning of the 20th century.

It is also possible the representation is by the reaction of dinitrogen pentoxide with ammonia

Or sodium sulfamate with nitric acid.

Properties

Nitrylamid is a very decomposable solid which is in the form of shiny, white flakes. It is a very weak acid, and soluble in ether, alcohol, water and acetone, a little soluble in benzene, and sparingly soluble in ligroin. It has a monoclinic crystal structure with space group C2 / c. It melts with partial decomposition, the solution weakly acid reaction and decays with increasing speed in nitrous oxide and water. The hydrolysis is catalyzed by nitramide for example, only of bases, but not of an acid and is an example of a general base catalysis. Johannes Nicolaus Brønsted formulated his acid-base concept based on studies on the catalytic decomposition of nitramide.
