Dérivés nitrés acétylés du glycolurile

A green synthesis of glycoluril derivatives in aqueous solution with recycle of the waste

“…The initial step probably involves the hydration of the carbonyl groups and then the phosphorylation by P 4 In addition, the reaction goes to completeness giving the same product yield even when it is carried out with only 0.1 eq. of P 4 O 10 .…”

Spectro-thermal decomposition study of 1,4-dinitroglycoluril (DINGU)

“…1,4-Dinitroglycoluril (DINGU) [1] is one of the important explosives, which has been of interest to the HEMs community in the recent past. This insensitive explosive is also a precursor to one of the most powerful explosive, viz.…”

Synthesis of the glycoluril derivatives by the HZSM-5 nanozeolite as a catalyst

“…Na + in NaZSM-5 was replaced with NH 4 + by impregnating NaZSM-5 in the solution of 1 mol/l NH 4 Cl solution at 363 K for 2 h. The exchange procedure was repeated for three times using fresh NH 4 Cl solution to ensure a complete exchange of Na + cations. Then, it was washed by distilled water, dried at 393 K, and calcined at 773 K for 5 h to decompose NH 4 + to H + and to form the acidic HZSM-5 zeolite.…”

“…HZSM-5 was prepared by ion exchange of NaZSM-5 with NH 4 Cl. Na + in NaZSM-5 was replaced with NH 4 + by impregnating NaZSM-5 in the solution of 1 mol/l NH 4 Cl solution at 363 K for 2 h. The exchange procedure was repeated for three times using fresh NH 4 Cl solution to ensure a complete exchange of Na + cations.…”
