Silver permanganate

The kinetics and mechanism of vacuum decomposition of AgMn04 at 378—393 K [466] are believed to differ from the behaviour of KMn04 in that the effective chain branching coefficient diminishes with time and this leads (Chap 3, Sect. 3.2) to the modified form of the Prout—Tompkins equation [Pg.194]

This expression fitted the acceleratory period of the a—time curves, followed by first-order decay and E = 122 2 kJ mole-1. No disintegration of small crystals was observed but pre-irradiated crystals [909] shattered on completion of the induction period. X-ray diffraction studies [910] confirm the existence of strain during the formation of decomposition product. Addition of small amounts (5% by mass) of ZnO or Th02 accelerated the decomposition of AgMn04 at 388 K. Ti02 reduced the rate, while NiO and Co304 had no effect [911]. [Pg.194]

Attempts to relate the kinetic characteristics of permanganate decompositions to the nature of the constituent cation have been discussed by Young [29]. [Pg.194]


Silver Permanganate. Silver permanganate [7783-98-4] AgMnO, is a violet soHd formed when a potassium permanganate solution is added to a silver nitrate solution. It decomposes upon heating, exposure to light, or by reaction with alcohol. [Pg.90]

Silver permanganate [7783-98-4] M 226.8, d 4.49. Violet crystals which can be crystallised from hot H2O (sol is 9g/L at 20°). Store in the dark. Oxidising agent, decomposed by light. [Pg.464]

This is known as the Prout—Tompkins equation and has found application to many systems, in addition to the thermal decomposition of potassium permanganate [465] with which it is often associated. The kinetic behaviour of silver permanganate was somewhat different and in a variation of... [Pg.67]

A very violent detonation occurred when silver permanganate was dried under vacuum in a dessicator containing sulphuric acid, it was thought that this accident was due to the formation of dimanganese heptoxide, which is extremely explosive through the action of sulphuric acid vapour on silver permanganate. [Pg.222]

TL5981>. The proposed mechanism involves the oxidation of the amine to an imine, tautomerization to an enamine, and a sequence of nucleophilic attacks on the pyridazine rings followed by oxidation steps. The oxidant of choice is (bispyridine)silver permanganate <1982TL1847>, which is easily prepared, mild in action, and is soluble in organic media. If R1 = H in the product 77, electrophilic substitution (e.g., bromination, nitration, Mannich, and Vilsmeier-Haack-Arnold reactions) occurs at this position. [Pg.877]

Several silver compounds are extremely explosive—for example, silver picrate, silver nitride, silver peroxide, silver perchlorate, and silver permanganate. They are used in various types of explosives and as concussion caps for rifle and pistol ammunition. [Pg.143]

MnOCH(CH2OMnOa)2 mw 397.88, OB to CO3 Mn02 —10.0%. There is no reference to this compound in die open literature. The inventor, Mr Emil Dvorak, claimed that the compd may be prepd by the reaction between silver permanganate triehlorohydrine. It was proposed as an... [Pg.752]

A useful expansion of the pyrrole-ring annelation methodology was found when 3-alkynyl-6,8-dimethylpyrimido[4,5-< ]pyridazine-5,7(6//,8//)-dione reacts with an amine and silver permanganate pyridine complex. It was postulated that first amination at the C4-position takes place, followed by an intramolecular cyclization into the pyrrolopyridazinopyrimidine derivative (Scheme 35). A similar reaction was reported with 6-alkynyl-l,3-dimethylpyrimido[4,5-Z]pyrazinedione (03MI3). [Pg.30]
