Tetramethylene diperoxide dicarbamide

Tetramethylene diperoxide dicarbamide (l,2,8,9-tetraoxa-4,6,ll,13-tetraazacy-clotetradecane-5,12-dione TMDD) was first synthesized by Girsewald in 1914 by the reaction of urea and formaldehyde with hydrogen peroxide in presence of nitric 

TMDD is prepared by dissolving urea and formaldehyde in hydrogen peroxide in 

The reaction mixture with dissolved reactants is then placed in a refrigerator for several days during which time TMDD precipitates [110, 129, 131]. The highest yield is, according to Pena-Quevedo, obtained after 3 days of the reaction [130]. This type of peroxide cannot be purified by crystallization due to its very low solubility in aU solvents organic solvents only remove soluble impurities in TMDD [110, 130, 131]. 

TMDD was suggested in 1934 as a component of priming mixtures for increasing the combustibihty of the mixture [132] and as a primary explosive for blasting caps [133].
