Dibasic Lead Stearate (CAS 56189-09-4) is a complex chemical compound with a unique set of properties that make it indispensable in several industrial applications, particularly as a PVC stabilizer. As a manufacturer and supplier, understanding its underlying chemistry is fundamental to appreciating its value.

The chemical formula for Dibasic Lead Stearate is often represented as C36H70O6Pb2, with a molecular weight around 1013.35 g/mol. This structure indicates that it is a lead salt derived from stearic acid, a long-chain fatty acid. The 'dibasic' designation points to the specific stoichiometry involving lead and the stearate anion, influencing its behavior and effectiveness as a chemical auxiliary agent.

In terms of physical properties, Dibasic Lead Stearate typically presents as a white powder. It is characterized by its insolubility in water, a common trait for metallic soaps with long hydrocarbon chains, but it shows solubility in certain organic solvents, particularly when heated, where it can form gels. These solubility characteristics are important for R&D scientists and product formulators to consider when incorporating it into various formulations.

The synthesis of Dibasic Lead Stearate generally involves reacting lead compounds with stearic acid under controlled conditions. While specific proprietary methods exist, common routes involve reactions between lead oxides or salts and stearic acid or its derivatives. The goal is to achieve the precise stoichiometry that yields the dibasic form, ensuring optimal performance as a stabilizer and lubricant. Manufacturers focus on controlling reaction parameters like temperature, pH, and reactant ratios to guarantee high purity and consistent quality.

Understanding these chemical properties and synthesis routes is crucial for anyone looking to buy Dibasic Lead Stearate. It allows for informed decisions regarding its application and handling. For instance, knowing its thermal stability range helps in selecting appropriate processing temperatures for PVC, while its chemical inertness under typical storage conditions ensures a good shelf life when stored correctly.
