Understanding Cas No 7758-16-9: Sodium Phosphate Dibasic

Cas No 7758-16-9 refers to Disodium Phosphate, also known as Dibasic Sodium Phosphate. This versatile chemical compound has a wide range of applications across diverse industries, including food processing, pharmaceuticals, water treatment, and detergents. It's a crucial ingredient for buffering, pH regulation, and as a source of phosphate. This article provides a comprehensive overview of Disodium Phosphate, its properties, applications, safety considerations, and sourcing information. We’ll explore why China Seasoning is a trusted supplier of high-quality Cas No 7758-16-9.

Chemical and Physical Properties of Cas No 7758-16-9

Disodium Phosphate (Na₂HPO₄) is an odorless, white, crystalline solid. It's highly soluble in water, forming alkaline solutions. Its molecular weight is approximately 141.96 g/mol. Importantly, it exhibits a buffering action, meaning it resists changes in pH. This property makes it incredibly valuable in applications where maintaining a stable pH is critical. It's a hygroscopic substance, meaning it readily absorbs moisture from the air. Furthermore, it’s non-toxic, contributing to its widespread use in food and pharmaceutical industries. Its pH in a 1% solution is typically between 9.0 and 11.5.

Applications Across Industries: Cas No 7758-16-9 in Action

The versatility of Disodium Phosphate drives its application in numerous sectors. In the food industry, it functions as a buffering agent, emulsifier, and nutritional supplement. It's frequently found in processed cheeses, baked goods, and meat products. Within pharmaceuticals, it's used as a laxative, saline component in enemas, and as a buffering agent in various formulations. Water treatment utilizes it for softening and corrosion control. Detergent formulations benefit from its ability to improve cleaning performance. Finally, it’s used in laboratory settings as a buffer in biochemical experiments. China Seasoning provides Disodium Phosphate suitable for all these applications.

Cas No 7758-16-9: Grades and Specifications

Disodium Phosphate is available in several grades, each tailored to specific applications. These include Food Grade, Pharmaceutical Grade, and Industrial Grade. Food and Pharmaceutical grades are subject to stringent purity standards and are manufactured under Good Manufacturing Practices (GMP). Industrial Grade is typically less pure and used for technical applications like water treatment. Here’s a sample specification table:

Property	Specification (Food Grade)
Assay (Na2HPO4)	≥ 97.0%
pH (1% Solution)	9.0 - 11.5
Water Insoluble Matter	≤ 0.05%
Heavy Metals (as Pb)	≤ 10 ppm

Safety Considerations and Handling of Cas No 7758-16-9

While generally considered non-toxic, Disodium Phosphate can cause mild irritation to the skin and eyes. Avoid direct contact and wear appropriate personal protective equipment (PPE) such as gloves and safety glasses when handling. In case of contact, rinse thoroughly with water. Avoid inhaling dust, and ensure adequate ventilation during use. Store in a cool, dry place, away from incompatible materials like strong acids. Consult the Safety Data Sheet (SDS) for detailed safety information.

Frequently Asked Questions (FAQs)

What are the main applications of Disodium Phosphate?

Disodium Phosphate has a remarkably broad range of applications. It’s heavily utilized in the food industry as a buffering agent, emulsifier, and nutrient. In pharmaceuticals, it functions as a laxative and in saline solutions. It plays a role in water treatment for softening and corrosion control. The detergent industry incorporates it to boost cleaning performance. Its buffering capabilities also make it vital in laboratory settings for biochemical experiments. Essentially, any application requiring pH stabilization or a source of phosphate can benefit from Disodium Phosphate.

How is Disodium Phosphate different from other phosphate salts?

Disodium Phosphate (Na₂HPO₄) is just one member of the phosphate salt family. Monosodium Phosphate (NaH₂PO₄) is more acidic, while Trisodium Phosphate (Na₃PO₄) is more alkaline. The differing numbers of sodium ions attached to the phosphate group result in varying pH levels and chemical properties. Disodium Phosphate offers a balanced pH and is generally preferred when a buffering agent is needed. Choosing the correct phosphate salt depends on the specific application and desired pH.

What are the storage requirements for Disodium Phosphate?

To maintain the quality of Disodium Phosphate, it should be stored in a cool, dry, and well-ventilated area. It's hygroscopic, meaning it absorbs moisture from the air, so keeping it sealed in an airtight container is crucial. Avoid storing it near strong acids or oxidizing agents, as these can cause reactions. Proper storage will prevent caking and ensure the product remains effective for its intended use.

Is Disodium Phosphate environmentally friendly?

Disodium Phosphate is generally considered environmentally friendly when used and disposed of responsibly. While excess phosphates in waterways can contribute to eutrophication (excessive nutrient enrichment), responsible use and adherence to wastewater treatment regulations minimize this risk. It's biodegradable, and its components are naturally occurring. However, it's essential to follow local environmental guidelines for disposal.
