Product Description
What is Diallyl Dimethyl Ammonium Chloride?
Diallyl Dimethyl Ammonium Chloride (DADMAC), being a water-soluble quaternary ammonium compound, is extensively utilized across industries such as water treatment, papermaking, and textiles. Known for its excellent cationic properties, it serves as a monomer in the production of polymers and copolymers, offering flocculation, coagulation, and antistatic effects.
DADMAC is synthesized through a quaternization reaction between dimethylamine and allyl chloride under controlled conditions. The reaction generally takes place in a solvent like ethanol or water at moderate temperatures (30–50°C), with constant stirring to maintain uniformity. Afterward, the product undergoes purification to eliminate impurities and obtain a high-purity liquid form. This preparation process ensures consistent quality and high efficiency for industrial applications.
