Overview
Potassium adipate is the potassium salt of adipic acid, widely recognized for its role as a buffering agent and pH regulator. It is commonly utilized in food processing and industrial applications due to its stability and solubility. The compound is synthesized through the neutralization of adipic acid with potassium hydroxide, resulting in a white crystalline powder that is easy to handle and incorporate into various formulations. As a food additive, potassium adipate is often used to maintain desired acidity levels in processed foods. Its industrial applications extend to chemical synthesis and laboratory uses, where precise pH control is essential. The compound is favored for its non-toxic nature and compatibility with other ingredients.
Physical and Chemical Properties
Potassium adipate is characterized by its white crystalline appearance and high solubility in water. It decomposes at around 300°C, making it stable under typical processing conditions. The compound's molecular weight is 222.32 g/mol, and it exists as a dipotassium salt of adipic acid. Its buffering capacity is a key feature, allowing it to maintain pH levels effectively in various environments. The compound is non-hygroscopic, which enhances its shelf life and usability in formulations where moisture sensitivity is a concern.
Main Applications
In the food industry, potassium adipate serves as a pH regulator and buffering agent in products such as beverages, dairy items, and baked goods. It helps stabilize acidity and improve taste profiles. The compound is also used in dietary supplements and pharmaceuticals where controlled pH is critical. Industrial applications include its use in chemical synthesis, particularly in reactions requiring precise pH adjustments. Additionally, potassium adipate finds utility in laboratory settings as a reagent or buffer solution component.
Safety and Storage
Potassium adipate is generally regarded as safe when handled properly. However, it is advisable to avoid inhalation or direct contact with skin and eyes. Personal protective equipment, such as gloves and goggles, should be used during handling. Storage recommendations include keeping the compound in a cool, dry place, away from moisture and incompatible substances. Properly sealed containers are essential to prevent degradation and ensure long-term stability.
B2B Procurement Guide
When sourcing potassium adipate, buyers should verify the supplier's compliance with relevant standards, such as food-grade or industrial-grade specifications. Purity levels and certifications should be confirmed to meet application requirements. Price ranges vary based on quantity and purity, with typical costs between $20 and $50 per kilogram. Bulk purchases may offer cost advantages. It is also prudent to assess the supplier's reliability, delivery timelines, and quality control measures to ensure consistent product performance.
