Ammonium nitrate molecular weight

Mixtures of hydrazine and other compounds form liquid explosives which have been described. A study of the detonability of binary and ternary mixtures of nitromethane—hydrazine-methanol showed that N2 H, sensitizes nitromethane and nitromethane-methanol mixtures to detonation (Ref 29). From 2-10% N2H, and 90-98% lower molecular weight nitroparaffins are claimed to be a water insoluble liquid explosive (Ref 22). Mixtures of hydrazine, ammonium nitrate and aluminum have been patented as explosive compositions with high air blast effects (Ref 32). [Pg.193]

PVA (Merck) with molecular weight of 72,000 and degree of saponification of 98.5-99.2%, was used as supplied, AN (Merck) was purified by reduced pressure distillation. Ceric ammonium nitrate (CAN) (Merck) was used after vacuum drying. Acetic acid (Merck), dimethylformamide (DMF) and dimethylsulfoxide (DMSO) (Merck) were used without further purification. Other reagents used in the study were also all Merck products. [Pg.52]

Additional tests with ammonium compounds were performed to address the effect of ammonium ion (see Fig. 8). It is clear that the catalyst inhibition was not based only on the presence of ammonium ion. Ammonium carbonate showed the largest inhibition of the glucose hydrogenation reaction, while chloride and hydroxide had lesser effects. Ammonium nitrate caused no apparent inhibition on glucose conversion. A similar lack of effect was shown with potassium nitrate. In the case of ammonium nitrate, the glucose conversion mechanism was affected, so that the sorbitol yield was reduced by about 20%, but numerous byproducts and overreaction products (lower molecular weight polyols) were evident. [Pg.816]

Therefore, a volatile buffer should be used if possible (e.g., ammonium acetate, ammonium nitrate). ESI-MS has been used as a detector for FFF analysis of low-molecular-weight ethylene glycol polymers [9], where the effect of different carriers on cluster formation was investigated. ESI-MS has been coupled to size-exclusion chromatography (SEC) in several applications for polymer analysis and other applications where FFF techniques can be successfully used, including proteins, neuropeptides, and DNA molecule segments. Modern ESI-MS has a broad range of flow rates from nanoliters per minute up to milliliters per minute. [Pg.520]

Ammonium nitrate is found as colorless or white to gray crystals or odorless beads with a molecular weight of 80.06 and specific gravity of 1.725 gem ... [Pg.103]

Liquid and solid samples are placed in an opened cup while volatile samples are placed in a gelatine capsule and placed in the cup as for a normal sample. A suitable absorption solution is placed at the bottom of the bomb along with the prepared sample. It may be necessary to include an aid with combustion resistant samples as a support to combustion and such additives are low molecular weight paraffin oils, ammonium nitrates, benzoic acid, decalin, etc. [Pg.73]

Commercial CE instruments only became readily available in the late 1980s, however, a vast array of information about different applications has been published. As well as the dyes themselves, CE can be used, for example, for the analysis of low molecular weight/simple ions (such as small anions, e.g. chloride, bromide, nitrate, chlorite, acetate, phthalate or small cations, e.g. alkali -i- alkali earth metals, ammonium, transition metals) or for aromatic amines. [Pg.306]

The ammonium salt which results from the transformation of sulfuryl amide can be converted to a silver salt, AgNSO ELO, by silver nitrate (64) and this readily gives AgNS02. The silver salt with methyl iodide yields the N-methyl derivative (LXXI) (61). Since molecular weight determinations show the methyl derivative to be a trimer, it may also be assumed that the salts, and particularly that of silver, are also trimeric. Attempts to isolate the hydrogen compound (LXIX) have so far failed, but Heinze and Meuwsen (64) have prepared many salts of (LXIX). They also were able to show that when the silver salt was decomposed with an equivalent quantity of hydrochloric acid a tribasic acid resulted which was to some extent stable in water. It readily lost two protons, but one proton was split off only with difficulty. The ion (LXX) clearly has a high stability. The dipyridinium salt of the trimeric sulfimide, which is derived from the ion (LXX), can be obtained (la) in a yield of 70% by reaction of amido-sulfuric acid chloride with pyridine at 20° ... [Pg.183]

Hydrazine nitrate has a good thermal stability. Its weight loss rate at 100 °C is slower than that of ammonium nitrate [20]. Its explosion point is 307 °C (50 % detonation) and explosion heat is about 3.829 MJ/kg. Because of no carbon elements, the detonation products are not solid and their average molecular weight is small. [Pg.7]

The nitrogen requirement of the brewing yeast cell may be met by ammonium ions (in which case the cell synthesizes the necessary carbon constituents of amino acids from fermentable sugars), amino acids or low molecular weight peptides [5]. Brewing strains do not appear to produce extracellular proteolytic enzymes and thus are unable to use polypeptides or proteins. Many yeast strains do however possess these abilities [6] and one strain of Saccharomyces has been reported to produce an extracellular protease [7]. Saccharomyces strains are unable to use either molecular nitrogen or nitrate ions. [Pg.186]

Aluminized ammonium nitrate-fuel oil (aluminized ANFO) is a popular commercial explosive. If a mixture contains 5% A1 by weight, what weights of ammonium nitrate (valence = -2) and fuel oil will make up the stoichiometric mixture Assume that ammonium nitrate forms Nj, 2 HjO, and evolves 1 O atom per formula unit. Also assume that fuel oil can be represented by -CH2-, with a molecular weight of 14 and a valence of +6. [Pg.30]
