New York, NY 10018 USA It is formed by burning elemental phosphorus in the abundant presence of oxygen. Chemical Name: Phosphorus PentoxideSynonyms: Diphosphorus Pentoxide, Phosphoric Anhydride, Phosphorus(V) OxideChemical Formula: P2O5Molecular Formula: P4O10CAS Number: 1314-56-3CAS Number (P4O10): 16752-60-6EC Number: 215-236-1. Sometimes called phosphoric anhydride, or diphosphorus pentoxide, this compound can be obtained in the form of a soft white powder or colourless crystalline solid. Many reactions that require the removal of a water molecule can utilize P2O5 such as the dehydration of amides to nitriles. By using the website you agree to our cookie policy. Suitable products for Phosphorus pentoxide P 2 O 5 Whether portable gas detectors, gas detection tubes or personal protective equipment - Dräger offers a comprehensive portfolio to protect you when handling hazardous substances. In these polymorphs, the terminal oxygen atom shown to have a double bond with the phosphorus atom actually forms a single bond, and links with another oxygen atom associated with a different tetrahedron. Many reactions that require the removal of a water molecule can utilize P2O5 such as the dehydration of amides to nitriles. ---------------------------------- Phosphorus pentoxide reacts with moisture on body tissue surfaces to form phosphoric acid, which approximates sulfuric acid and hydrochloric acids in corrosive … Application Phosphorus pentoxide may be used in the synthesis of dichlorine heptoxide (Cl 2 O 7). Phosphorus pentoxide Revision Date 19-Apr-2018 Notes to Physician Treat symptomatically 5. ► It is also used to form anhydrides of oxygen-conta… Fax: +41 27 722 57 12, © 2020 SMC Global All Rights Reserved. Frit Softening Point: Sublimates at 300C (From The Oxide Handbook) Dry M.O.R. The best way to use fertilizers to meet P requirements changes with crop, soil properties and environmental conditions. Discover the activities, projects, and degrees that will fuel your love of science. The majority of phosphorus pentoxide that is not used as a desiccant is used as an intermediary reactant to create other compounds. Unsuitable Extinguishing MediaWater Flash Point No information available Method - No information available Autoignition Temperature No information available Most practical applications and uses of phosphorus pentoxide are centered around its extreme affinity to water, which makes it an excellent dehydrating agent. However, one has to take a note of the fact…, Red phosphorus is one of the most common and widely used allotropes of the nonmetallic element, phosphorus. Fertilizer labels list these chemicals as three numbers, such as 10-15-10. The reaction with water is very vigorous and proceeds with the evolution of … Supplier details: American Elements 10884 Weyburn Ave. Los Angeles, CA 90024 Tel: +1 310-208-0551 Fax: +1 310-208-0351. It is a white crystalline solid, and is extremely hygroscopic, i.e., it has a very strong attraction to water. Would you like to write for us? *Please select more than one item to compare It is widely used in chemical analysis as a dehydrating agent and in organic synthesis as a condensing… Structure Chemical Formula and Uses of Phosphorus Pentoxide. Phosphorus pentoxide is used as a strong drying and dehydrating agent. Phosphorus pentoxide definition, a white, deliquescent, crystalline powder, P2O5, that, depending upon the amount of water it absorbs, forms orthophosphoric acid, metaphosphoric acid, or pyrophosphoric acid, produced by the burning of phosphorus in dry air: used in the preparation of phosphoric acids, as a drying and dehydrating agent, and in organic synthesis. Phosphorus pentoxide (P 2 O 5) is a phosphorous oxide. One of three major ingredients included in general fertilizers, phosphorus is essential for seed formation and important for flowering and root growth. Of the several uses of phosphorus, its use to make safety matches is perhaps the most familiar for the layman. The principle of operation applies Faraday’s Law … As a new method of forming phosphoric acid was discovered, this method fell out of fashion. Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. However, it doesn’t catch fire like most other compounds, i.e., it doesn’t react with atmospheric oxygen even if heated.
