Methylenedi-isonitramine

It fonns expl heavy metal salts, which according to Urbanski, are weaker initiators than the corresponding metal salts of methylenedi-isonitramine. The decreasing order of brisance of these salts, when primed with MF, in the Pb plate test were Na, Ca, Ba, H and Pb Refs 1) T. Urbanski T, Wesolowski, Wiad-TechnUzbr 18, 28 (1932) 2) T. Urbanski,... 

Traube [15] prepared methylenedi-isonitramine, the isomer of methylenedinitramine, in the form of a sodium salt, by the action of nitric oxide on acetone, in the pres-... 

The sodium salt of methylenedi-isonitramine was prepared by Traube [62] from acetone and nitric oxide in the presence of sodium alcoholate according to the following chain of reactions ... 

The sodium salt of methylenedi-isonitramine (II) is formed. In an aqueous solution this precipitates with the salts of heavy metals. Some of these salts (e.g. the thallium salt) have the properties of weak initiators. 

However, on investigating the ultra-violet absorption spectra of methylenedi-isonitramine, R. N. Jones and Thorn [67] failed to detect a band characteristic of... 

Urbanski and Piskorz [60] found that the properties of methylenedi-isonitramine salt differ markedly from those of methylenedinitramine salt. They also established that methylenedi-isonitramine is not a tautomeric modification of methylenedinitramine. In their most recent work [70] they have confirmed the nitrosohydroxylamine structure of isonitramines by examining the infra-red absorption spectra. 

Under the influence of aqueous solutions of the water soluble salts of heavy metals the sodium salt of methylenedi-isonitramine gives precipitates of the salts of these metals. T. Urbanski, Zacharewicz and Pietrzyk [61] suggested the use of certain heavy metal salts as initiators. Particularly interesting properties were demonstrated by the thallous salt CH2(N202n)2. 

Some of the heavy metal salts of nitromethylisonitramine appear to have initiating properties, which are however considerably weakened by the presence of a nitro group. The salts of type III are therefore weaker initiators than the corresponding metal salts of methylenedi-isonitramine. 

MEDINA in an acronym for MEthylene DINtrA-mine. In earlier literature it was called MEDNA (Ref 2), the latter name later used for the isomeric compd methylenedi-isonitramine which was obtained by the action of nitric oxide on acet (Beil 1, 592) (See under MEDNA in this...
