Let’s know about Perchloric Oxide Formula. Perchloric oxide , also known as chlorine oxide (VII), perchloric anhydride, dichloromethane, is an inorganic chemical compound of the formula Cl 2 O7. Its structure is presented in Figure 1 (EMBL-EBI, 2009).
Perchloric oxide produced is one of the most stable chlorine oxides and reacts with water to form perchloric acid.
Chlorine 2 O 7 + H 2 O D 2HClO 4
The compound is obtained by careful dehydration of perchloric acid with phosphorus pentoxide at -10 °C.
2HClO 4 + P 2 O 5 “Chlorine 2 O 7 + 2HPO 3
The compound is carefully distilled to separate it from metaphosphoric acid given its explosive nature (Aegon Wiberg, 2001). It can also be created by light in a mixture of chlorine and ozone.
Physical and Chemical Properties of Perchloric Oxide
Chlorine oxide (VII) is a volatile and oily colorless liquid (National Center for Biotechnology Information., 2017). Its molecular weight is 182.9 g / mol, its density is 1900 kg / m3 and the melting and boiling points are -91.57 ° C and 82 ° C, respectively (Royal Society of Chemistry, 2015).
It is explosive spontaneously upon impact or exposure to flame and especially in the presence of its decomposition products.
Chlorine heptoxide is dissolved in carbon tetrachloride at room temperature and reacts with water to form perchloric acid. Exposure to iodine.
Under normal conditions, it is more stable, although with a lower oxidizing power than other chlorine oxides. For example, it does not attack sulfur, phosphorus or paper when it cools.
Dichloro heptoxide is a strongly acid oxide, and forms an equilibrium with perchloric acid in solution. In the presence of alkali metal hydroxides form perchlorates.
Its thermal decomposition is produced by monomolecular dissociation of chlorine trioxide and radicals
response and threats
Perchloric oxide is a volatile compound. It decomposes slowly upon storage, producing colored decomposition products that are less chlorine oxide.
It is spontaneously explosive, especially in the presence of its decomposition products, incompatible with reducing agents, acids and strong bases.
Although it is the most stable chlorine oxide, Cl 2 O 7 It is a strong oxidant, as well as an explosive that can be extinguished with flame or mechanical shock, or by exposure to iodine.
However, it oxidizes less than other chlorine oxides, and does not attack sulfur, phosphorus, or paper when cooled. It has the same effect on the human body as elemental chlorine, and requires the same precautions.
Ingestion causes severe burning of the mouth, esophagus and stomach. The vapor is very toxic by inhalation.
In case of contact with eyes you should check if you are wearing contact lenses and remove them immediately. The eyes should be washed with running water for at least 15 minutes, keeping the eyelids open. You can use cold water. Ointment should not be used for the eyes.
If the chemical comes into contact with clothing, remove it as soon as possible, protecting your hands and body. Place the victim under a safety shower.
If the chemical is deposited on the victim’s exposed skin, such as hands, gently and carefully wash the skin with contaminated water and non-abrasive soap.
You can use cold water. If irritation persists, seek medical attention. Wash contaminated clothing before reuse.
In case of inhalation, the victim should be allowed to rest in a well-ventilated area. If the inhalation is severe, the victim should be evacuated to a safe area as soon as possible.
Loose clothing such as shirt collars, belts or ties. If the victim finds it difficult to breathe, oxygen should be administered.
If the victim is not breathing, mouth-to-mouth is resumed. Always bear in mind that it can be dangerous to the person who provides mouth-to-mouth resuscitation when the inhaled material is toxic, infectious or corrosive.
In all cases you should seek immediate medical attention.
Perchloric oxide has no practical application. It can be used as an oxidizing agent or for the production of perchloric acid but its explosive nature makes it difficult to handle.
Dichloro heptoxide can be used as a reagent for the production of perchlorates or for studies with various reactions.
In Kurt Baum’s work there are reactions of perchloric oxide with olefins (Baum, 1976), alcohols (Kurt Baum, reactions of dichlorine heptoxide with alcohol), alkyl iodide and acrylic perchlorate with esters (Kurt Baum). 1975) Obtaining halogens and oxidation.
In the case of alcohols, it reacts with simple alcohols such as ethylene glycol, 1,4-butadiene, 2,2,2-trifluoroethanol, 2,2-dinitropropanol to produce alkyl percolates. Reacts with 2-propanol to give isopropyl perchlorate. 2-Hexanol and 3-Hexanol give perchlorates without fixation and with their respective ketones.
Propane reacts with dichloro heptoside in carbon tetrachloride to give isopropyl perchlorate (32%) and 1-chloro,2-propylperchlorate (17%). The compound reacts with cis -butane to give 3-chlorobutyl perchlorate (30%) and 3-keto, 2-butyl perchlorate (7%).
Dichloro heptoxide reacts with primary and secondary amines to give N-perchlorates in carbon-tetrachloride solution:
2 RNH2 + Cl2O7 → 2 RNHClO3 + H2O
2 R2NH + Cl2O7 → 2 R2NClO3 + H2O
It also reacts with alkanes to give alkyl perchlorates. For example, it reacts with propene in carbon tetrachloride solution to produce isopropyl perchlorate and 1-chloro-2-propyl perchlorate (Beard and Baum, 1974).
