HMTD is an explosive of the initiating type it is more powerful and brisant than MF, rather being comparable to LA and Cyanuric Triazide. It does not become dead-pressed even at pressures of 11000 psi (an advantage over MF)... 

Behavior Toward Flame when a small quantity is ignited, it flashes like NC, giving a flame several inches in height Brisance by Sand Test 0.5 g at 1000 psi pressure crushes 42.5 g compared with 44.2 g for Cyanuric Triazide and 16.5 g for MF Power by Trauzl Test, about 60% of TNT or 230% of MF (Ref 11)... 

Cyanuric Triazide, first prepd by Cahors, and in 1887 the process was improved by James. Taylor Rinkenbach prepd it in 1923 1927 in pure state and detd its expl props (Ref 70, pp 66—68). See also Vol 3 of Encycl, pp C590-R C591-L...

As already mentioned, MF was largely (and now wholly) displaced since 1930 by LA (Lead Azide) and also by DAzDNPh (Diazo-dinitrophenol), Cyanuric Triazide and LSt (Lead Styphnate). This took place first in... 

Knaggs [10] found that in the case of cyanuric triazide the distance between the pairs of nitrogen atoms is not the same, being 1.26 and 1.11 A respectively. Examination of the Raman spectrum of sodium azide solutions has confirmed the chain structure of hydrazoic acid (Langseth, Nielsen and Sorensen [11]). The same conclusion is drawn from investigations of the absorption spectrum in the infra-red (Herzberg et al. [12]). 

A powerful initiator in which azido groups are combined with a heterocyclic ring is cyanuric triazide (XI) ... 

On reaction with chlorine, hydrogen cyanide gives cyanogen chlorides, forming a trimer—cyanuric chloride (XII). The latter is a liquid with a melting point of 146°C and a boiling point of 196°C. Next, cyanuric triazide (XI) is obtained by the action of sodium azide in an aqueous solution, at room temperature on compound (XII). 

Cyanuric triazide is insoluble in water, sparingly soluble in cold alcohol and readily soluble in hot alcohol, acetone, benzene, chloroform, ether, and molten trinitrotoluene, It is slightly hygroscopic and slightly volatile. It irritates the skin causing dermatitis. Its heat of formation — AHf is 219kcal/mole (H. Muraour [162]). 

Another structural feature of importance is the bond angle R—N—N. This angle has the value 116° for structure A (unstrained), 108° for Bf and 180° for C (the value 116° applies also to J , but with the plane of the molecule normal to that for A) (Sec. 4-8). An average value would be expected for resonance among several structures. The observed values, 120° 10° in methyl azide, 114° 3° in cyanuric triazide, and 112.7° 0.5° in hydrogen azide, are in agreement with the value expected for resonance between A arid C, about 112°. 

In addn to the initiating compds mentioned above(MF and LA) the following may also be used LSt, DADNPh, TATNB, Cyanuric Triazide, Tetracene or a mixt of LA 80-90 K chlorate 20 -10%(See also Additional References on Blasting Cap Compositions, which are given below)...

Jones Sheffield(Ref 5) also discussed the relationship between brisance(as detd by the Sand Test) and deton velocity but their data cannot be included here because it is classified Refs I)H.Kast A.Haid,ZAngewChem 38,50-2 (1925) (Brief discussion on relationship betw brisance and detonation velocity for initiating expls cyanuric triazide, LA, LSt, MF and 90/10-MF/KC103) 2)T.Urbanski,SS 30,68-71(1935) CA 29,4941(1935) [For expls such as TNT or AN expls, detonation velocity may be calcd from the equation D = (24.9Sp)2 where D is detonation velocity, Sp is compression of Cu cylinder in mm minus correction 0.16mm (Compression produced by a No 8 cap)i This relationship does not hold for some chlorate expls] 3)W.H.
