Product Overview
Acrylamide (abbreviated as AM) is an important organic chemical intermediate with the molecular formula C₃H₅NO. At room temperature, it appears as a colorless, transparent liquid, exhibiting both weak acidic and weak basic reaction characteristics. This product is manufactured using the carrier‑free microbial catalytic technology originally developed by Tsinghua University, a process known for its high catalytic activity, excellent selectivity, and high conversion rate of acrylonitrile. Compared with traditional copper‑catalyzed processes, this product contains no copper or iron ions in its system, with low impurity levels. It is particularly suitable for producing high‑molecular‑weight polyacrylamide with a relatively uniform molecular weight distribution, and is also applicable to the manufacture of various homopolymers, copolymers, and modified polyacrylamide products.
With over two decades of professional experience in the chemical industry, our company has established a stable supply system and a rigorous quality control workflow, supported by our strategic location in the Zibo chemical industrial cluster. The following sections detail the technological highlights, product specifications, and application areas of this acrylamide grade.
Technological Advantages: Carrier‑Free Microbial Catalysis
Proprietary Tsinghua University technology. This process employs immobilized cell biocatalysis, operating under normal temperature and pressure. It offers low energy consumption, high operational safety, and achieves a consistently high conversion rate of acrylonitrile. Compared with conventional chemical catalysis, the biological route inherently avoids the introduction of metallic ions such as copper and iron, resulting in a notably purer product.
Purity benefits of carrier‑free design. The carrier‑free microbial process does not introduce any carrier materials during production, thereby minimizing external impurities from the source. Specific advantages include:
- Zero copper/iron ions: Eliminates interference from metal ions in downstream polymerization reactions, making this product especially suitable for polymer synthesis systems that are sensitive to metallic contaminants.
- Low impurity content: Residual acrylonitrile, acrylic acid, and other by‑products are controlled at low levels, ensuring reliable stability in downstream applications.
- High activity and purity: High‑purity monomer provides a solid foundation for polymerization, facilitating the production of polymers with a uniform molecular weight distribution.
Suitability for polyacrylamide production. Owing to its low impurity profile and high monomer purity, this product enables better control over the polymerization process when used as a raw material for polyacrylamide. This is particularly valuable in applications requiring precise molecular weight parameters, such as enhanced oil recovery (EOR) polymers for tertiary oil extraction and high‑performance flocculants for water treatment.

Storage and Handling Recommendations
Acrylamide monomer is classified as a toxic substance, and its aqueous solution is prone to spontaneous polymerization under high‑temperature or prolonged sunlight exposure. It is recommended to store the product in a cool, well‑ventilated area away from direct sunlight. Appropriate personal protective equipment should be worn during handling, and direct skin or eye contact should be avoided.
