Chemical compound

Urea perchlorate is a sheet-shaped crystallite with good chemical stability and strong hygroscopicity. It has usage as an oxidizer in liquid explosives[1] including underwater blasting.[2]

Synthesis

The compound is synthesized by gradual addition of urea into a perchloric acid solution:

CO(NH2)2 + HClO4 → CO(NH2)2·HClO4

An alternative route is addition of urea to hydrochloric acid solution, followed by addition of sodium perchlorate, and filtration of the salt.

NaClO4·H2O + CO(NH2)2 + HCl → CO(NH2)2·HClO4 + NaCl + H2O
