They et al. (1993) evaluated the degradation of aldicarb at nine different temperatures. When aldicarb was oxidized at a temperature range of 275-650 °C, the following reaction products were identified by GC/MS acetone, 2-methyl-2-propenenitrile, methylthiopropene, dimethyl disulfide, carbon dioxide, carbon monoxide, nitrous oxide, isocyanatomethane, hydrogen azide, sulfur dioxide, hydrogen cyanide, and 2-propenenitrile. 

Use. Liq HNj has been found by McKinney (Ref 39) to act as a solvent for many- substs, especially inorg compds Hydrogen Azide, Aqueous or Hydrozoic Acid (HA), HN, nHjO (aq distillate has contd up to 27% HNj, Ref 94, p 183) was first obtained in 1890 by Curtius(Ref 1) on treatment of benzoyl azide with NaOH, followed by distn with H,SO . Subsequently Cuftius used instead of NaOH, Na ethylate (Ref 5) and also ale ammonia(Ref 8). Methods of prepn employed by other investigators may be divided into the following general classes a)di>ec/ syntheses (Refs 78,88 131a) b) interaction of hydrazine and nitrous acid(Re(s 7,9,11,35,55,62 64) c)oxidation of hydrazine (Refs 15,19,20,21,22,36,42,48,49,52,68,74 ... 

AZIDA de BARIO (Spanish) (18810-58-7) Highly unstable in dry form. Dust forms explosive mixture with air. Heat, shock, or friction can cause spontaneous decomposition and explosion. Forms shock-sensitive mixtures with lead and other heavy metals. Contact with barium, iron, or sodium will increase its sensitivity to explosion. Contact with acids forms corrosive hydrogen azide. Reacts violently with oxidizers, carbon disulfide. Commercially available in ethyl alcohol. Keeping the chemical wet greatly reduces its explosion hazard. 

AZIDA SODICA (Spanish) (26628-22-8) Reacts with hot water. Explosive decomposition in elevated temperatures above 525°F/274°C. Forms ultra-sensitive explosive compounds with heavy metals copper, copper alloys, lead, silver, mercury, carbon disulfide, trifluoroacryloyl fluoride. Violent reaction with acids, forming explosive hydrogen azide. Violent reaction with bromine, barium carbonate, chromyl chloride, dimethyl sulfate, dibromomalononitrile. Incompatible with caustics, cyanuric chloride, metal oxides, metal sulfides, methyl azide, phosgene.
