Sulfonated Aliphatic Polyester, identified by its CAS number 1639-66-3, is a vital chemical intermediary and performance additive across a spectrum of industrial applications. As a leading manufacturer in China, NINGBO INNO PHARMCHEM specializes in producing this versatile anionic surfactant, offering it to businesses seeking high-quality inputs at competitive prices. Understanding its chemical properties is essential for formulators aiming to leverage its full potential.

Chemical Profile and Key Characteristics

Sulfonated Aliphatic Polyester is characterized by its amphiphilic nature, featuring both hydrophilic sulfonate groups and hydrophobic alkyl chains. This structure imparts excellent surface-active properties, including wetting, penetration, emulsification, and foaming. Its typical appearance is a colorless to light yellow liquid. While it readily dissolves in water, forming milky white solutions, it exhibits good stability in neutral to slightly acidic conditions. However, it is noted that the compound is susceptible to hydrolysis in alkaline environments, especially at elevated temperatures, and can react with heavy metal salts and reducing agents.

Production and Synthesis Insights

The synthesis of Sulfonated Aliphatic Polyester typically involves a multi-step process. This commonly includes the esterification of maleic anhydride with an appropriate alcohol (such as 2-ethylhexanol), followed by sulfonation using agents like sodium metabisulfite. This carefully controlled manufacturing process ensures a product with high purity and consistent performance, critical for demanding industrial applications.

Applications Driving Industrial Demand

The unique properties of Sulfonated Aliphatic Polyester make it highly sought after in several industries:

  • Textile Industry: It acts as a rapid penetrating agent, crucial for even dyeing and bleaching, and as a wetting agent in finishing processes. Companies looking to buy these specialized textile auxiliaries often rely on its efficacy.
  • Pesticide Formulations: It serves as an effective emulsifier, improving the stability and application of agricultural chemicals.
  • Industrial Cleaning: Its detergency and emulsifying power make it a valuable component in heavy-duty cleaning agents.
  • Other Chemical Processes: It can also function as a general-purpose surfactant in various chemical manufacturing contexts.
