Detailed Product Overview
Phosphoric Acid (85%), with the chemical formula H₃PO₄ and a CAS number of 7664-38-2, is a colorless to slightly yellow viscous liquid. It is characterized by a high purity of 85% and a molecular weight of 98.00 g/mol. The acid is completely soluble in water, facilitating its integration into various chemical processes. Its high boiling point of 158 °C and a melting point of 42.35 °C make it suitable for applications requiring thermal stability. The density of 1.685 g/cm³ and viscosity of 20.0 mPa·s at 20 °C contribute to its handling characteristics, making it an efficient reactant in many formulations. In industrial settings, Phosphoric Acid (85%) is indispensable in the production of fertilizers, where it serves as a critical source of phosphorus. This nutrient is essential for plant growth, significantly impacting agricultural productivity in East Africa. In food processing, its food-grade variant ensures compliance with stringent safety standards, acting as an acidulant and preservative. The technical grade is widely used in industrial cleaning agents, where its acidic nature effectively removes rust and scale. Furthermore, it plays a crucial role in metal treatment processes, such as phosphating, which enhances corrosion resistance and paint adhesion. Kivi Industrial Chemicals Limited offers Phosphoric Acid (85%) in both food grade and technical grade, tailored to specific industry needs. The food grade is compliant with FSSAI standards, making it suitable for food-related applications. In contrast, the technical grade is optimized for industrial uses, such as fertilizers and cleaning agents. Buyers should verify the assay/purity, ensuring it meets the minimum 85% specification. The appearance should be a clear, colorless to slightly yellow liquid, as any deviation could indicate contamination. Additionally, the refractive index and pH of the solution should align with the provided specifications to confirm product integrity. Proper handling and storage of Phosphoric Acid (85%) are crucial to maintaining its quality and safety. It should be stored in a cool, dry place in tightly sealed containers to prevent moisture ingress and contamination. The product is available in 25 kg polyethylene drums and 200 kg steel drums, providing flexible packaging options to suit different operational scales. As a corrosive material, appropriate personal protective equipment should be used during handling. Kivi Industrial Chemicals Limited ensures that the packaging is robust and compliant with safety regulations, facilitating safe transport across Kenya, Uganda, Tanzania, and the wider East African market.
