At storage, in one of the divisions, I saw recently two 5 gal, original , containers of seventy (70) % H2O2 which is stabilized with H3PO4 or Stannate/Tin. The shipping label says May 1995, the storage temps vary from 35 - 120 F thru the years. There is no pressure, bulging, nor any decomposition apparent. However once opened, H2O2 can explosively decompose into steam and O2 if/when in contact with traces of catalysts like dust particles, in particular rust, MnO2, Cigarette ash, KMnO4 or silver-mesh etc. "conc" H2O2 (ONLY 3% and up) is nasty piss. Put it onto your skin and within seconds the skin turns ashen white and produces badly itching blisters, even if you wash it off right away. [Only registered and activated users can see links.

Click Here To Register...]> [snip] Bleaching peroxide from the chemists for hair bleaching is 6%. [snip] -------------------- RT Holtzamnn Chemical Rockets and Flame and Explosive Technology Marcel Dekker 1969 b. HYDROGEN PEROXIDE. In high strength, i.e., 90-100%, hydrogen peroxide has a high boiling point, high density, low viscosity, and with certain metalized systems is very high performing. The preparation and properties of hydrogen peroxide have been well documented (115). Much of the operational experience has also been reported (116). The stability of high strength hydrogen peroxide depends largely on the nature of the container in which it is stored and the concentration of adventitious impurities present in solution or in suspension (117) Empirical studies on container materials and additives during the past 50 years have produced a variety of techniques for passivating container surfaces and decreasing the activity of catalytic ions present in solution. It has only been in the past three years that high strength peroxide could be considered storable over long periods of time (118,119). In practice, because of slow decomposition and occasional explosions, high strength peroxide has found little application as a bipropellant and is mainly employed as a monopropellant or gas generator (120). This application is discussed more extensively below. (4) Hydrogen peroxide. With suitable catalysts it is possible to decompose H20, according to the equation: H202(l) = H20(g) + 1/2O2 + 12.96 kcal (2-26) Thermochernical calculations (120) on 100% H201 show the chamber temperature to be 1250'K and the specific impulse 146 sec at a 20-to-I pressure ratio. Because of this low performance, H102 cannot compete with the other members of the class A monopropellants, but it is interesting to note that as a result of the simplicity of operation of H202 motors and because of the low chamber temperature H202 was actually used in military weapons by the Germans in World War II. Examples of systems utilizing H2O2 catalyzed by calcium permanganate are (1) the Focke-Wolf ATO Fw56 which developed 650 lb thrust for 30 sec, (2) pilot-controlled units for the Henkel He 112 and He 126 rocket motors, and (3) the Messerschmitt Me 163-A rocket airplane with a thrust of 1650 lb. In spite of its low theoretical 1,,,, useful rocket application can be made of this monopropellant because of its high efficiency (as measured by c*) and its high liquid density (1.39 gm/cm3 for commercial 90% H202 at 20oC. Considerable application has also been made of the gas-generating properties of H202 (as, for instance, in the German V-2) because of ease of ignition and low temperature of the product gases. Hydrogen peroxide is normally manufactured as an aqueous solution. Prior to World War 11, concentrations no higher than 30-35% were generally available. As a result of interest in H2O2 as a rocket propellant, however, commercially available solutions of H201 containing up to 99 % are now produced by means of vacuum distillation of the more dilute solutions. For high performance it is desirable to employ as high a concentration of H202 as possible, whereas in certain gas-generating devices it may be advantageous to add water in order to lower the decomposition temperature. Calculations show that an 87 % solution will yield a temperature of 930'K (320'K decrease for 13 % H20) and an I., of only 126 sec (20 sec decrease). The use of aqueous solutions Of H202 may be desirable because of their low freezing points. A considerable amount of work has been done on the kinetics of the catalytic decomposition of dilute H2O2 solutions. It is known that permanganate solutions are effective catalysts for the decomposition of H202 and, in fact, calcium permanganate has been used very successfully for the ignition of peroxide motors (120). Once the decomposition has been started, the reaction proceeds smoothly with a nonluminous exhaust. Calcium permanganate can be used in two ways, i.e., as a concentrated aqueous solution injected together with the H201, and also as a catalytic surface on Alundum pellets which are soaked with the catalytic solution, dried, and then packed into the motor chamber. Both methods have been found satisfactory. High strength hydrogen peroxide can be decomposed reliably into superheated oxygen gas and water vapor at a predetermined temperature depending upon the H102 concentration and the initial temperature of the solution. The decomposition catalyst used to the greatest extent is the solid samariurn oxide coated silver screen (135). However, decomposition via a liquid catalyst is feasible and it has been employed in systems where short firing durations are used. The treated silver screen catalyst normally is arranged in a tightly compressed pack (Fig. 2-16). When the hydrogen peroxide passes over and around the wires of the pack screens, silver ions pass into the H2O2 solution. These silver ions react with the H202 molecule decomposing it into oxygen gas and water vapor with heat being liberated. This heat increases the reaction rate by raising the. temperature of the screens and the H202. In a matter of milliseconds the H202 reaction rate has increased to a point where the adiabatic decomposition temperature of the H201 is reached. This reaction rate continues indefinitely if required unless foreign matter poisons the silver. The disadvantages in the use of H20, either as a monopropellant or in a bipropellant combination are its thermal sensitivity, which requires vented containers for shipping and storage, and its high freezing points.** Concentrated H20, reacts with many metals, and the oxides formed catalyze the decomposition reaction. If poured on oxidized iron, concrete, dust, or clothing, the exothermic decomposition becomes so rapid that an explosion may result if the liquid is partially confined. This property constitutes a hazard and great care should be exercised in handling H202, to avoid spillage. Concentrated H,O, is practically inert, however, in contact with 2S aluminum alloy and polyethylene, Teflon and Kel-F plastics (136). A detailed description of the equipment suitable for handling concentrated H202 has been given by Davis and Keefe (136). With reasonable handling care and with the use of proper materials for containers, these authors conclude that concentrated peroxide solutions can be handled on a large scale with safety. -------------------------------------- GP Sutton Rocket Propulsion Elements 5th ed. John Wiley 1986 Hydrogen Peroxide (H202) In rocket application, hydrogen peroxide has been used in a highly concentrated form of 70 to 99%; the remainder is water. Commercial peroxide is approximately 30% concentrated. It was used in rocket applications between 1938 and 1965 (X-I and X-15 research aircraft), but is no longer used today, primarily because of its storage stability problems. In the combustion chamber, the propellant decomposes according to the following chemical reaction, forming superheated steam and gaseous oxygen: H202 --> H20+ 1/2O2 + heat This decomposition is brought about by the action of catalysts such as various permanganates, manganese dioxide, platinum, and iron oxide. In fact, most impurities act as a catalyst. The theoretical specific impulse of 90% hydrogen peroxide is 147 sec, when used as a monopropellant. Even under favorable conditions H202 Will often decompose at a slow rate during storage and gas will bubble out of the liquid. Contaminated liquid peroxide must be disposed before it reaches a danger point of about 448oK, when an explosion may occur. Concentrated peroxide causes severe burns when in contact with human skin and may ignite and cause fires when in contact with wood, oils, and many other organic materials. ------------ H2O2 Omnium gatherum Hydrogen peroxide of 80-85% strength under the name “T-Stoff” was used by the Germans during WW II in submarines. “U-Boat, Walter” After Dr. Helmuth Walter. Reacted with calcium permanganate H2O2 produced oxygen for use in submarine diesel engines, the energy liberated (690 kcal/g calculated for 100% peroxide) was in the form of steam utilized to operate gas turbines directly connected to propeller shaft. Seven such submarines (300 to 500 tons each) were accepted by the German Navy up to the end of WW II. Hydrogen peroxide with K or Na peroxide (Z-Stoff) produced superheated steam (180o C) for rockets &c. Hydrogen peroxide mixtures were also code named: Ingolin, Aurol, Neuralin and Subsidol. -------------------------------------------- Production of hydrogen peroxide: From Ammonium bisulphate by electrolysis. By oxidation of alkylhydroanthraquinones (Quinone process) Oxidation of isopropyl alcohol. Laboratory production is from barium peroxide. This is an expensive way of making H2O2! Hydrogen peroxide above 30% can be some really interpreting stuff! There being a geometric relationship between interesting and dangerous!!

curious chemistry too - hydrogen peroxide packed with releasable oxygen atoms One torpedoe aboard "Kursk" cought on fire without prior warning. This happened because of sudden hydrogen peroxide decomposition in the torpedo. Within short time the high explosives detonated, setting off the other torpedoes. With the nose section completely blown off, Kursk sunk. US and british Navy removed hydrogen peroxide-fuelled torpedoes from usage despite their superb performance compared to battery-powered torpedoes.
