The diazotization of amino derivatives of six-membered heteroaromatic ring systems, particularly that of aminopyridines and aminopyridine oxides, was studied in detail by Kalatzis and coworkers. Diazotization of 3-aminopyridine and its derivatives is similar to that of aromatic amines because of the formation of rather stable diazonium ions. 2- and 4-aminopyridines were considered to resist diazotization or to form mainly the corresponding hydroxy compounds. However, Kalatzis (1967 a) showed that true diazotization of these compounds proceeds in a similar way to that of the aromatic amines in 0,5-4.0 m hydrochloric, sulfuric, or perchloric acid, by mixing the solutions with aqueous sodium nitrite at 0 °C. However, the rapidly formed diazonium ion is hydrolyzed very easily within a few minutes (hydroxy-de-diazonia-tion). The diazonium ion must be used immediately after formation, e. g., for a diazo coupling reaction, or must be stabilized as the diazoate by prompt neutralization (after 45 s) to pH 10-11 with sodium hydroxide-borax buffer. All isomeric aminopyridine-1-oxides can be diazotized in the usual way (Kalatzis and Mastrokalos, 1977). The diazotization of 5-aminopyrimidines results in a complex ring opening and conversion into other heterocyclic systems (see Nemeryuk et al., 1985). 

Derbyshire and Waters202 carried out the first kinetic study, and showed that the chlorination of sodium toluene-m-sulphonate by hypochlorous acid at 21.5 °C was catalysed more strongly by sulphuric acid than by perchloric acid and that the rate was increased by addition of chloride ion. A more extensive examination by de la Mare et al.203 of the rate of chlorination of the more reactive compounds, anisole, phenol, and />-dimethoxybenzene by hypochlorous acid catalysed by perchloric acid, and with added silver perchlorate to suppress the formation of Cl2 and C120 (which would occur in the presence of Cl" and CIO-, respectively),... 

Rather different experimental results were obtained by de la Mare et a/.208, 209, who studied chlorination by hypochlorous acid in 51, 75 and 98 % aqueous acetic acid. With the latter medium, the chlorination of anisole or m-xylene (at an unspecified temperature) was independent of the concentration of aromatic, and catalysed by perchloric acid to a much greater extent than an equimolar amount of lithium perchlorate the reaction was also catalysed by the base, sodium acetate. The reactive species was postulated as chlorine acetate produced...

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. 

Ammonium perchlorate, NH4C104.—The perchlorate is formed by mixing solutions of barium perchlorate and ammonium sulphate, by the action of ammonium nitrate on sodium perchlorate,8 and by that of ammonium chloride on calcium or magnesium perchlorate.10 It forms rhombic,11 doubly refracting crystals,12 of density 1 88 at 25° C. Its solubility at 18° C. is 21 07 grams in 100 grams of water.18 It is de-... 

The anodization process uses high purity A1 foils. Before anodization the aluminum foil is de-greased with acetone or trichloroethylene for some time followed by a sodium carbonate wash at around 80 °C and vacuum annealed (typically 10 Pa) at around 500 °C for a few hours. This is followed by an electrochemical polish in acidic solution (like perchloric acid and ethanol mixture or H3PO4, H2SO4 and Cr03 mixture). The anodization process is a two-step process as shown in Figure 21.5. In the first step the oxidation is carried out in 0.3 M-0.5 M acid medium at... 

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%) ...

Polymers. The nylon 11 and polyethylene were commercial mate-rials (Societe Organico, Paris, France, and E. I. du Pont de Nemours Co., Inc., Wilmington 98, Del.). All the other polymers were prepared from the dry salt by bulk melt polymerization. Pertinent data for the samples used are collected in Table I. Amine ends were determined by titration with perchloric acid in 85% phenol-methanol solution and carboxyl ends by titration with sodium hydroxide in benzyl alcohol. Other analyses were by standard methods. Elemental analyses confirmed the identity of the polymers. Each was a pure sample, except nylon 11, which contained 0.26% of an unidentified inorganic material.
