Product Description
Product name: Phosphorus Pentoxide (P₂O₅)
Recognized names: Phosphorus pentoxide; Phosphorus(V) oxide; Diphosphorus pentoxide; Phosphoric anhydride; P₂O₅
Molecular formula: P₄O₁₀; the conventional empirical formula is P₂O₅.
Molar mass: 283.89 g/mol for P₄O₁₀ (141.94 g/mol per P₂O₅ empirical unit).
CAS Number: 1314-56-3
EC Number: 215-236-1
Thermal data depend on the crystalline form; use the current TDS and SDS for the offered material.
Handling boundary: the material can sublime and is highly moisture-reactive; design transfer and storage from the current SDS.
Water interaction: reacts exothermically with water to form phosphoric acids; it should not be described simply as water-soluble.
Density: confirm crystalline form, particle form and the applicable value on the offered specification.
Appearance: white, highly hygroscopic solid; confirm particle form and any colour limit on the offered specification.
Industrial use: dehydrating and condensing reagent and phosphorus-chemistry feedstock. Confirm assay basis, impurity profile, physical form and process compatibility; this page does not establish pharmaceutical, electronic or food suitability.
FAQ - Technical & Supply Chain
-
Q:
Are Phosphorus Pentoxide and P4O10 the same material?
A: Phosphorus pentoxide is the commercial name for phosphorus(V) oxide, whose molecular form is commonly represented as P4O10; CAS 1314-56-3 is used for the commercial material. It is not phosphoric acid or a hydrated phosphate. Specify the available-P2O5 assay basis and intended process. -
Q:
What are the main industrial uses of Phosphorus Pentoxide?
A: It is used as a dehydrating and condensing reagent and as a phosphorus-chemistry feedstock. Confirm assay basis, impurity profile, physical form and process compatibility; the product identity alone does not establish pharmaceutical, electronic or food suitability. -
Q:
Which specifications should be agreed for industrial Phosphorus Pentoxide?
A: Set available P2O5 assay and method, free phosphoric acid, water, insoluble matter, iron, heavy metals and particle form. Because hydration changes the composition, state whether the specification is reported on an as-received or P2O5 basis. -
Q:
Is Phosphorus Pentoxide simply water-soluble?
A: No. It reacts exothermically with water to form phosphoric acids and should not be handled as an ordinary water-soluble solid. Controlled addition, moisture exclusion and thermal precautions are required, along with confirmation of the crystalline form and particle characteristics for the offered material. -
Q:
How should Phosphorus Pentoxide be stored and packaged?
A: Store in dry, moisture-tight compatible packaging and protect it from humid air, water and incompatible materials. Because the material can sublime and is highly moisture-reactive, confirm configuration, handling controls, net quantity and destination before quotation, and use suitable dry handling and transfer procedures.
