Question

show the urotropin reaction​

Answer 1

Answer:

Hexamethylenetetramine or methenamine, also known as hexamine or urotropin, is a heterocyclic organic compound with the formula (CH2)6N4. This white crystalline compound is highly soluble in water and polar organic solvents. It has a cage-like structure similar to adamantane. It is useful in the synthesis of other chemical compounds, e.g., plastics, pharmaceuticals, rubber additives. It sublimes in vacuum at 280 °C.

Explanation:

Hexamethylenetetramine was discovered by Aleksandr Butlerov in 1859.[2][3] It is prepared industrially by combining formaldehyde and ammonia.[4] The reaction can be conducted in gas phase and in solution.

The molecule has a symmetric tetrahedral cage-like structure, similar to adamantane, whose four "corners" are nitrogen atoms and "edges" are methylene bridges. Although the molecular shape defines a cage, no void space is available at the interior for binding other atoms or molecules, unlike crown ethers or larger cryptand structures.

The molecule behaves like an amine base, undergoing protonation and N-alkylation (e.g. Quaternium-15).
