Copper permanganate, decomposition

In a review of the course and mechanism of the catalytic decomposition of ammonium perchlorate, the considerable effects of metal oxides in reducing the explosion temperature of the salt are described [1], Solymosi s previous work had shown reductions from 440° to about 270° by dichromium trioxide, to 260° by 10 mol% of cadmium oxide and to 200°C by 0.2% of zinc oxide. The effect of various concentrations of copper chromite , copper oxide, iron oxide and potassium permanganate on the catalysed combustion of the propellant salt was studied [2], Similar studies on the effects of compounds of 11 metals and potassium dichromate in particular, have been reported [3], Presence of calcium carbonate or calcium oxide has a stabilising effect on the salt, either alone or in admixture with polystyrene [4],... 

The oxidation of primary aliphatic alcohols by l w(2,2,-bipyridyl)copper(ll) permanganate (BBCP) in aqueous acetic acid leads to the formation of the corresponding aldehydes446. The oxidation of [l,l-2H2]ethanol exhibited446 a kn/kn of 4.50. The formation constants for BBCP-alcohol complexes and the rates of their decomposition have been evaluated. Aliphatic aldehydes are oxidized by pyridinium hydrobromide... 

DOT CLASSIFICATION 4.3 Label Danger When Wet, Corrosive, Flammable Liquid SAFETY PROFILE Moderately toxic by inhaladon. Corrosive. A severe irritant to skin, eyes, and mucous membranes. Ignites spontaneously in ait. A very dangerous fire hazard when exposed to heat or flame. Forms impact-sensitive explosive mixtures with potassium permanganate, lead(II) oxide, lead(TV) oxide, copper oxide, silver oxide. To fight fire, use water, foam, CO2, mist. When heated to decomposition it emits toxic fumes of CL. See also CHLOROSILANE.
