Perform a blank determination (see General Provisions), and make any necessary correction. Each milliliter of 0.1 N perchloric acid is equivalent to 29.43 mg of C14H18N205. 5-Benzyl-3,6-dioxo-2-piperazineacetic Acid Mobile Phase Weigh and transfer 5.6 g of potassium phosphate monobasic into a 1-L flask, add 820 mL of water, and dissolve. Adjust the pH to 4.3 using phosphoric acid, add 180 mL of methanol, and mix. Filter through a 0.45-pim disk, and de-gas. 

Manufacture of these explosives received great impetus in Germany and France during World War I, probably on account of the lack of nitrogen compounds. Composition The chief constituent, 60-80 per cent, is a chlorate or perchlorate of ammonium, sodium, or potassium. The other ingredients are combustible products such as charcoal, sulfur, aluminum powder, or mixtures of vegetahle meals uitro derivatives of benzene, toluene, naphthalene, phenol and as de-sensitizers solid hydrocarbons (paraffin) and castor oil may he added. The addition of the nitro compounds serves to improve the propagation.

Various other reagents can be used for this reductive debromination. 1,2-Dipropylcyclopropane was prepared from 4,6-dibromononane using chromium(II) perchlorate in dimethylformami-de/water (yield 93%), lithium amalgam in tetrahydrofuran (75%), lithium biphenylide in te-trahydrofuran (78%), potassium-sodium alloy in tetrahydrofuran (68%), zinc dust and zinc(II) chloride in propan-2-ol/water (95%) and alkyllithiums in tetrahydrofuran (BuLi 16%, i-BuLi 18%, t-BuLi 47%). Ring closure of 1,3-dibromobutane to methylcyclopropane was achieved by treatment with zero-valent copper, which was obtained from reaction of lithium naphthalen-ide and copper(I) iodide/tributylphosphane in tetrahydrofuran (yield 91%) ... 

CIANURO de ZINC (Spanish) (557-21-1) Reactions with acids, acid fumes, acid salts, or elevated temperatures release hydrogen cyanide gas. Can react violently with magnesium, nitrates. Incompatible with nitrites, chlorates. Mixtures of metal cyanides with metal chlorates, nitrates, nitrites, or perchlorates may cause violent explosions. Incompatible with strong oxidizers, bromine, chlorine, fluorine, mercurous chloride, nitric acid. Violent reaction with sodium nitrite. Forms sensitive explosive mixtures with potassium chlorate. 

CLORURO de NIQUEL (7718-54-9) Violent reaction with chlorine nitrate, potassium. Mixing with potassium produces an impact-sensitive explosive. Forms heat- or shock-sensitive explosives with ammonium nitrate. Increases sensitivity to heat, impact, or friction of hy-drazinium perchlorate. Incompatible with chloric acid, gold, lithium, sodium acetylide. 

FOSFURO de ZINC (Spanish) (1314-84-7) Combustible solid. Dust forms explosive mixture with air. Reacts with water, steam, moisture in air, acids, and/or heat, producing fumes of phosphorus, zinc oxides, flammable phosphine. Reacts violently with strong oxidizers, chlorine, fluorine, nitric acid, sulfuric acid, perchloric acid. Incompatible with carbon dioxide, halogenated compounds. Reacts with most common extinguishing agents. Forms heat-, friction-, and shock-sensitive explosive mixtures with potassium chlorate, potassium nitrate, sodium chlorate. In case of fire, use Class D extinguishers or smothering quantities of dry sand, crushed limestone, clay.
