{"product_id":"phosphoric-acid-85-technical-grade","title":"Phosphoric Acid 85% - Technical Grade","description":"\u003ch2\u003eProduct Overview\u003c\/h2\u003e\u003cp\u003ePhosphoric acid 85% Technical Grade is a highly concentrated mineral acid represented by the chemical formula H3O4P with a molecular weight of 97.995 g\/mol. Identified globally under CAS number 7664-38-2, this inorganic acid acts as a crucial reagent and chemical intermediate across numerous heavy industries — primarily utilized in surface prep and synthesis. In its technical form, it presents as a clear, colorless, and odorless liquid that is denser than water, featuring a density of 1.892 at 77 °F (USCG, 1999). Alliance Chemical distributes this high-purity industrial grade through our curated collection of \u003ca href=\"\/collections\/acids\"\u003eacids\u003c\/a\u003e to meet the rigorous demands of manufacturing plants, surface finishing facilities, and agricultural compounding operations nationwide.\u003c\/p\u003e\u003cp\u003eThis technical grade formulation contains 85% active phosphoric acid, providing a consistent, low-impurity profile tailored specifically for non-food and non-medical industrial applications. Unlike dilute variations, the 85% concentration offers maximum chemical activity and lower water content, allowing precise formulation control and reducing shipping volumes. As a primary source of phosphorus, it serves as an essential building block in the synthesis of industrial compounds and surface prep solutions. Our commitment to chemical distribution excellence ensures that every batch is supported by full documentation to maintain compliance and process integrity.\u003c\/p\u003e\u003ch3\u003eWhy This Grade\u003c\/h3\u003e\u003cp\u003eSelecting the 85% Technical Grade over other concentrations or grades is vital for process predictability and economic efficiency. Technical grade chemical distribution requires a careful balance; using an analytical reagent grade where it is not required adds unnecessary expense, while using a lower-purity or highly diluted acid can introduce critical process failures. For example, in surface treatment and rust conversion, trace metallic impurities found in substandard grades can interfere with the phosphate coating process, leading to poor paint adhesion or premature metal corrosion. The 85% concentration level provides the exact chemical equilibrium required to establish stable acid baths without introducing excess water that would slow down reaction times or dilute active baths too rapidly.\u003c\/p\u003e\u003cp\u003eFurthermore, choosing an incorrect grade or concentration introduces significant failure modes into industrial processes. Substituting other concentrations instead of our standard \u003ca href=\"\/products\/phosphoric-acid-85-technical-grade\"\u003ePhosphoric Acid 85% - Technical Grade\u003c\/a\u003e can alter the pH dynamics of complex chemical mixtures or cause precipitation of critical components. In industrial applications like catalyst manufacturing or pH adjustment in highly buffered systems, precise control over the hydronium ion concentration is necessary. Utilizing our standardized 85% Technical Grade ensures consistent viscosity, predictable boiling and melting points, and reliable reaction kinetics, preventing costly batch rejections and unplanned system downtime.\u003c\/p\u003e\n\u003cdiv class=\"chemical-profile\" data-source=\"canonical\"\u003e\n\u003ch3\u003eChemical Profile\u003c\/h3\u003e\n\u003cdl\u003e\n\u003cdt\u003eCAS Number\u003c\/dt\u003e\n\u003cdd\u003e7664-38-2\u003c\/dd\u003e\n\u003cdt\u003eChemical Formula\u003c\/dt\u003e\n\u003cdd\u003eH3O4P\u003c\/dd\u003e\n\u003cdt\u003eMolecular Weight\u003c\/dt\u003e\n\u003cdd\u003e97.995 g\/mol\u003c\/dd\u003e\n\u003cdt\u003eBoiling Point\u003c\/dt\u003e\n\u003cdd\u003egreater than 266 °F at 760 mmHg (USCG, 1999)\u003c\/dd\u003e\n\u003cdt\u003eMelting Point\u003c\/dt\u003e\n\u003cdd\u003e108 °F (NIOSH, 2024)\u003c\/dd\u003e\n\u003cdt\u003eSpecific Gravity\u003c\/dt\u003e\n\u003cdd\u003e1.892 at 77 °F (USCG, 1999) - Denser than water; will sink\u003c\/dd\u003e\n\u003cdt\u003eAppearance\u003c\/dt\u003e\n\u003cdd\u003ePhosphoric acid appears as a clear colorless liquid or transparent crystalline solid.
