Ethylenediamine chlorate

Suggestion that ethylenediamine chlorate might be used in explosive manufacture was made by Stahler [4] who reported the substance to be a very strong explosive, sensitive to impact. So far it has not found commercial application. 

Having considered the explosive chlorates, the explosive properties of chlorine dioxide, C102 should also be mentioned. Chlorine dioxide is a mixed chlorous-chloric anhydride 

There are several methods of manufacturing is on a commercial scale, for instance the calcination of oxalic add blended with potassium chloride, treatment of sodium chlorite with chlorine, or of sodium chlorate with sulphur dioxide in the presence of concentrated sulphuric add. Chlorine dioxide is utilized as a strong bleaching agent for cellulose, paper, flour, oils and such like, as well as a solvent for removing lignin from wood pulp. 

Under normal condition it exists as a gas that it condensed at +10°C, and freezes at —76°C. In the condensed or solid state, chlorine dioxide explodes even while being poured from one vessel into another. The expansion produced in the lead block is 200 cm3. It was recently suggested as a component in liquid propellants for rockets.

It is remarkable for its ability to take part in the formation of coordination cqmpds, such.as ammines (See Vol 1 of Encycl, pp A275fO some of these compds are expl, as, for example, copper complexes described here under Ethylenediamine Complexes . On neutralization with nitric acid it forms the expl Ethylenediamine Dinitrate (See below), while under other conditions it gives the expl Echylenedinitramine, which, however, is usually prepd by nitrating ethyleneurea.

In this study, the stability of bromate in water samples with different matrix constituents was investigated. Water samples ranged from soft to hard and were spiked with 1 mg/L bromide, 0.5 mg/L chlorite and 0.5 mg/L chlorate. These levels are considered to be higher than those normally observed in waters for these three anionic species. Each sample was also spiked with 2.5, 10 and 25 pg/L of bromate. Fiuthermore, a 5 pg/L of bromate standard in deionized water was also prepared. Brown glass bottles capped with polypropylene tops and PTFE inserts were used as sample containers. Samples were stored in the dark at 4 °C. Tables 2.5 and 2.6 summarize matrix constituents of each sample, preservation method spike levels and results of analyses. The results clearly demonstrate that for the two high and low total hardness waters tested, samples containing 2.5 to 25 pg/L bromate were stable for at least 20 days and that the addition of 50 mg/L ethylenediamine (EDA) preservative did not affect the results, as illustrated in Table 2.6. The results also confirm that 5 pg/L bromate standard made up in deionized water had the same stability over this period.
