• Effects of Short Term Exposure: The substance is irritating to the eyes and respiratory tract. The substance may cause effects on the central nervous system. This may result in impaired vigilance and performance. Inhalation of the gas may cause lung oedema. The effects may be delayed. The liquid may cause frostbite.
• Effects of Long Term Exposure: Repeated or prolonged inhalation of the gas may cause effects on the lungs.
• Description: Ozone in the upper layers of the atmosphere (stratosphere) is formed by the reaction of O2 with the elemental oxygen formed from the splitting of O2 by UV radiation. The ozone layer in the stratosphere, though containing a relatively low amount of O3 relative to O2, absorbs UV radiation and serves to protect Earth fromthe destructive andmutagenic properties of solarUV.Ozone is more unstable than O2 and thus more reactive. Ground-level ozone (troposphere) is formed largely fromthe reactionof the byproducts of the incomplete combustion of fossil fuels with elemental oxygen present. Common industrial pollutants and car exhaust by-products such asnitrogen oxides, sulfur oxides, carbon oxides, and hydrocarbons are photochemically cleaved and then react with the O2 present. Natural sources of tropospheric ozone come from ozone migration from the stratosphere with average concentration of about 10–20 ppb in nonurban areas. Tropospheric ozone can be very harmful to human health, and people with conditions such as emphysema, asthma, bronchitis, and heart conditions are especially susceptible. Health effects from ozone are due to its high reactivity resulting in reactions with biological macromolecules and subsequent cellular damage. In addition, ozone conversion to diatomic oxygen results in the production of free oxygen radicals, which can also cause damage. Due to the harmful health effects of ozone, theUS Environmental Protection Agency (EPA) among other government entities has established exposure limits. The National Ambient Air Quality Standards limit for ozone is 0.075 ppm, taken as the annual fourth-highest dailymaximum8 h concentration, averaged over 3 years. Ozone exceeds its limit more often than all other regulated air chemicals, and is in excess most frequently in California.
• Physical properties: Ozone is an allotropic molecular form of oxygen containing three atoms of oxygen (O3).It is a much more powerful oxidizing agent than diatomic oxygen (O2) or monatomic oxygen(O). It is the second most powerful oxidizer of all the elements. Only fluorine is a strongeroxidizer. It is not colorless as is oxygen gas. Rather, ozone is bluish in the gaseous state, butblackish-blue in the liquid and solid states (similar to the color of ink).Ozone’s boiling point is –112°C, and its freezing point is –192°C.
• Uses: Ozone is much more reactive than O2, which makes it a very powerful oxidizing agent.Only fluorine is more reactive. It has many commercial uses. It is a strong oxidizer, particularlyof organic compounds, it is a strong bleaching agent for textiles, oils, and waxes, and it is apowerful germicide. It is also used in the manufacture of paper, steroid hormones, waxes, andcyanide and in the processing of acids.Ozone produced by electrical discharge is used to purify drinking water and to treatindustrial wastes and sewage. It is also use to deodorize air and kill bacteria by passing dry airthrough special ozone-producing electronic devices. Ozone is used as an oxidizing compound, as a disinfectant for air and water, for bleaching waxes and oil, and in organic synthesis. It occurs in the atmosphere at sea level to about 0.05 ppm. It is produced by the action of ultraviolet (UV) radiation on oxygen in air. As disinfectant for air and water by virtue of its oxidizing power. For bleaching waxes, textiles, oils. In organic syntheses. Forms ozonides which are sometimes useful oxidizing Compounds.

An efficient and convenient synthesis of enantiopure 4-(t-butyldimethylsilyloxy)-cyclohex-2-en-1-one: A formal synthesis of (±)-mesembranol

10.1016/S0040-4039(01)00481-6

The research focuses on the efficient and convenient synthesis of enantiopure 4-(t-butyldimethylsilyloxy)-cyclohex-2-en-1-one (2a), a valuable chiral building block, and a formal synthesis of (±)-mesembranol (17). The purpose of the study was to develop an inexpensive and efficient route to 2a, leveraging the chiral vinyl triflate methodology. The key starting material was (+)-limonene oxide 1, which was converted through a series of reactions involving ozonolysis, Baeyer–Villiger oxidation, hydrolysis, and silylation to yield compound 4. Further reactions included regiospecific conversion of the epoxide mixture to allylic acetates, acylation, and elimination of acetate to yield diene 6. The synthesis concluded with oxidative cleavage and purification steps to obtain enone 2a, which was then used in the formal synthesis of (±)-mesembranol. The chemicals used in the process included (+)-limonene oxide, ozone, methanol, diisobutylaluminum-diisopropylamine, acetyl chloride, palladium catalysts, and various other reagents and solvents. The study concluded that the synthesis was high yielding and that the methodology could be readily scaled up for larger quantities, with a focus on avoiding chromatography and using distillation for purification.

10.1023/A:1016103023539

The research investigates the synthesis of ethyl benzoate through the ozonolysis of styrene in the presence of ethanol. The purpose of this study is to explore a potentially industrial method for producing ethyl benzoate, a compound with applications in various sectors including dyes, lubricants, herbicides, and cosmetics. The process involves the ozonolysis of styrene, which is then thermally decomposed to yield ethyl benzoate. The study concludes that the method is commercially feasible, with a maximum yield of available oxygen achieved at a molar ratio of styrene to ethanol of 1:1.5. Key chemicals used in the process include styrene, ethanol, ozone, and various intermediates such as molozonide, bipolar ions, and carbonyl compounds. The final products were ethyl benzoate, ethyl formate, formaldehyde, benzaldehyde, formic acid, and benzoic acid.
