Acrylamide CAS#79-06-1

Basic Information

Acrylamide

Acrylamide is a water-soluble monomer supplied as a white crystalline solid or transparent flakes. Its principal use is the manufacture of polyacrylamide and related copolymers, rather than direct substitution for those finished polymers. Downstream applications include water-treatment flocculants, mineral-processing separation aids and papermaking additives. It also supplies intermediate chemistry for selected substituted acrylamides and related monomer production.

product description

High Water Solubility: Acrylamide (CAS 79-06-1) is a white crystalline solid with high solubility in water. Solubility in organic solvents varies considerably and is limited in many common solvents; compatibility should be confirmed for the intended formulation.


Monomer for Polymer Production: Acrylamide is primarily used to manufacture polyacrylamide and related copolymers for water treatment, papermaking, mineral processing, and other industrial applications. Acrylamide monomer must not be confused with the finished polymer.


Purchasing Specifications: Key parameters include acrylamide content, moisture, color, inhibitor content where applicable, and impurity limits. Product form and specifications should be confirmed against the intended manufacturing process.


Carcinogenicity and Health Hazards: Acrylamide is classified as probably carcinogenic to humans (IARC Group 2A). It also presents neurotoxicity and genotoxicity hazards and can be absorbed through the skin. Prevent inhalation, ingestion, and skin contact through suitable engineering controls and protective equipment.


Storage and Polymerization Risk: Acrylamide can undergo hazardous polymerization under unsuitable conditions. Store according to the supplier’s SDS, protected from excessive heat and incompatible substances. Follow product-specific requirements for temperature control, stabilization, and storage duration.

Product Description of Acrylamide CAS#79-06-1

Acrylamide is a white crystalline solid and a key raw material for polyacrylamide. Known as AM, it is usually colorless transparent flakes in commercial form. It dissolves readily in water, methanol, ethanol and propanol, and sparingly in ethyl acetate, chloroform and benzene. It hydrolyzes to acrylic acid under acidic or alkaline conditions.

It is also a fundamental precursor to many monomers, including methacrylamide, anionic AMPS, cationic DMC, and various N-substituted acrylamide derivatives.


Product Application of Acrylamide CAS#79-06-1

Over 90% of acrylamide goes into polyacrylamide (PAM) production, with the rest used for N-methylolacrylamide (NMA) and other related monomers. Of PAM consumption, around 60% is for water treatment, 20% for pulp and paper, and 10% for mineral processing.

Acrylamide polymers are widely used in solid-liquid separation as flocculants for mineral processing, wastewater treatment and water purification to reduce sludge volume. They also act as additives in paper, paperboard, leather and coatings. In papermaking, PAM works as a retention aid in wet-end processing and improves wet strength.
