Various methods have been explored for the synthesis of potassium, sodium, and lithium ozonides. The physical and chemical properties of potassium ozonide, which could be readily prepared in pure form (88- 97%), have been characterized by studies of the compound’s thermal stability, its reaction with water vapor, and its reaction with carbon dioxide. The handling and storage characteristics of potassium ozo- nide have also been determined. Theoretical discussions of chemical non-regenerative air revitalization systems in general, and of the synthesis and chemistry of alkali metal ozonides in particular, are presented in this report. ix I I NTRODUCT ION 1.1 GENERAL The complexity of the problems associated with the exploration of outer space by the use of manned vehicles is gradually and systematically being overcome to the extent that at the present time the goals set for this extensive exploration are in sight. One of the major objectives still to be achieved is the development of reliable and safe air revital- ization systems. During the years of study devoted to such a develop- ment, there has appeared to evolve a subtle feeling on the part of many investigators that a search for a panacea; i.e., one system to meet the requirements of all space missions, should constitute our main effort in this area. In effect, such thinking spells out the requirements for the development of a reliable, completely regenerative, air revitaliza- tion system. Such a philosophy, on the part of those who espouse it, is valuable and should be encouraged. The experience accumulated to date, however, dictates that this thinking must not predominate to the extent that the importance of fundamental research studies necessary to develop non-regenerative air revitalization systems be minimized. Also, such systems should not be simply viewed as stopgap measures taken to fill the void until all manned space missions can be met with a regenerative system. In fact, it appears to be quite clearly established that non-regenerative air revitalization system should, for many years to come, provide the most economical and reliable means of maintaining a habitable atmosphere for space missions which will last for at least one man-month. Among the missions adaptable to such systems are: 1. Shuttle trips to manned space stations. 2. Near-earth scientific space explorations. 1 3. Near-earth military reconnaissance missions. 4. Orbital space station excursion vehicles. 5. Extravehicular manned space equipment. 6. Emergency back-up systems for long-term space missions requiring a regenerative technique as the primary life support system. The requirements of such missions emphasize the importance of continuing the search for efficient, safe, light-weight, small-volume air revital- ization materials. An important phase of this search has been the work carried out on unfamiliar oxidation state inorganic chemicals such as peroxides, superoxides, and ozonides. The most spectacular results in this area have come from Russian researchers, due in great measure to their patient and extensive investigations of fundamental problems, the solution of which are so necessary. if successful life support sys- tems and engineering studies are to be obtained. This report presents the results of the first Government -sponsored proj- ect devoted specifically to the investigation of the air revitalization potential of one of the most promising groups of unfamiliar oxidation state inorganic chemicals, the alkali metal ozonides.

    Ozone Factfile

    OZONE CHEMISTRY: This site aims to provide information on the chemistry of ozone and provide some useful links to other pages. Ozone is an atmospheric compound, found both at ground level and in the stratosphere. It also is responsible for various chemical reactions. Ozone is crucial for life as we know it, preventing harmful radiation from reaching the earth. But, it also has a not so nice side. Low level ozone is partly responsible for photochemical smog's in our cities and also presents a health hazard. This site will give you the low down on low and high level ozone, as well as having a look at the ozone hole and the chemistry behind this unique compound. Ozone Factfile Standard State: gas Boling temperature: -111.9 °C Melting temperature: -195.5 °C Specific Gravity: 2.144 Formula: O3 Colour: Pale Blue Occurs: naturally in troposphere Formed: From nitrogen oxides and organic oxides emitted as a product of combustion engines or from passing an electric current through air. The name ozone comes from the Greek ozein, for "to smell". It is an allotropic form of oxygen having three atoms in each molecule, formula O3. It is, in standard state, a pale blue, highly poisonous gas with a strong odour. Liquid ozone is a deep blue and strongly magnetic. Ozone is formed when an electric spark is passed through oxygen, and causes a detectable odour near electrical machinery. The commercial method of preparation consists of passing cold, dry oxygen through a silent electrical discharge. Ozone is much more active chemically than ordinary oxygen and is a better oxidising agent.

    Potassium Hydroxide (P6310)

    Potassium hydroxide ACS Reagent Product Number P 6310 Store at Room Temperature 22,147-3 is an exact replacement for P 6310 Product Description Preparation Instructions Molecular Formula: KOH This product is soluble in water (100 mg/ml), yielding a Molecular Weight: 56.11 clear, colorless solution. Potassium hydroxide is also CAS Number: 1310-58-3 soluble in alcohol (1 part in 3) and glycerol (1 part Melting point: 360 °C, 380 °C (anhydrous)1 in 2.5). The dissolution of potassium hydroxide in water or alcohol is a highly exothermic (heat- This product is in the form of pellets. It is designated producing) process.1 as ACS Reagent grade, and meets the specifications of the American Chemical Society (ACS) for reagent Storage/Stability chemicals. Potassium hydroxide rapidly absorbs carbon dioxide and water from the air and deliquesces.1 Potassium Potassium hydroxide (KOH) is a caustic reagent that is hydroxide solutions should be stored in plastic bottles widely used to neutralize acids and prepare potassium (polyethylene or polypropylene). KOH solutions will salts of reagents. It is used in a variety of large-scale etch glass over a period of just a few days. applications, such as the manufacture of soap, the mercerizing of cotton, electroplating, photoengraving, References and lithography.1 1.
