Diallyldimethylammonium Chloride (DADMAC) CAS 7398-69-8: A Cornerstone Cationic Monomer from NINGBO INNO PHARMCHEM CO.,LTD.

NINGBO INNO PHARMCHEM CO.,LTD. is pleased to highlight the availability of high-quality Diallyldimethylammonium Chloride, commonly known as DADMAC. Identified by its CAS number 7398-69-8 and chemical formula C8H16ClN, DADMAC stands as a pivotal chemical intermediate and a versatile cationic monomer with extensive applications across numerous industries. Our commitment to quality and supply chain reliability ensures that clients receive DADMAC that meets stringent performance requirements for their diverse processes.

Key Properties and Chemical Nature

DADMAC is recognized primarily as a powerful cationic monomer due to the presence of a quaternary ammonium group within its structure. This functional group carries a permanent positive charge regardless of the pH conditions, making DADMAC and its derived polymers effective cationic agents. The inherent strong polarity contributes significantly to its reactivity and interaction with negatively charged substances in various systems. According to technical specifications, DADMAC typically presents as a colorless liquid in its common commercial forms, often as an aqueous solution, though data suggests potential availability in solid or powder states depending on specific requirements or derivative forms. It exhibits a refractive index of approximately n 20/D 1.460 and possesses the chemical identifiers BRN 5830817 and the InChIKey GQOKIYDTHHZSCJ-UHFFFAOYSA-M.

A notable characteristic of DADMAC, as highlighted by its industrial applications, is its excellent resistance to salt and alkali environments. This stability allows it to maintain its effectiveness in challenging conditions where other chemicals might degrade or lose efficacy. This resilience is particularly valuable in applications involving high salinity or fluctuating pH levels.

Wide-Ranging Industrial Applications

The versatility of DADMAC stems from its ability to undergo polymerization, either through homopolymerization (forming PolyDADMAC) or copolymerization with other vinyl monomers. This process allows the incorporation of the quaternary ammonium group into polymer chains, creating polymeric structures with strong cationic properties. These resultant polymers and copolymers find critical uses in various sectors:

Water Treatment: This is perhaps the most significant application. DADMAC-based polymers act as primary coagulants and flocculants. Their positive charge effectively neutralizes the negative surface charges on suspended solids, colloidal particles, and dissolved organic matter present in water. This neutralization leads to the aggregation of these smaller particles into larger, settleable or filterable flocs, thereby clarifying water. This mechanism is essential in municipal drinking water treatment, industrial wastewater purification, sewage treatment, and sludge dewatering processes. The ability to function effectively across various pH conditions further enhances its utility in this field.

Papermaking Industry: In papermaking, DADMAC and its polymers serve multiple functions. They are used as retention aids to improve the retention of fine fibers, fillers, and pigments within the paper sheet, reducing loss and improving yield. They also act as drainage aids, helping water to drain more quickly from the paper pulp on the machine wire, leading to faster production speeds and energy savings. Furthermore, they can improve paper strength by promoting better bonding between fibers.

Printing and Dyeing Industry: DADMAC polymers are employed as fixing agents for dyes and pigments. The cationic charge interacts strongly with anionic dyes, forming insoluble complexes that prevent the dye from washing out, thus improving color fastness on textiles and paper. They can also function as dispersants or leveling agents.

Oilfield Additives: In the oil and gas industry, DADMAC-based chemicals are utilized in various formulations, including demulsifiers for separating oil from water emulsions, corrosion inhibitors to protect metal pipes and equipment, and friction reducers in drilling fluids and hydraulic fracturing operations.

Resin Synthesis: As a monomer, DADMAC is a fundamental building block for synthesizing a range of specialized cationic polymers and copolymers used in coatings, adhesives, and other functional materials. The polymerization can be initiated by free radical initiators, such as peroxides or azo compounds, to create tailor-made polymeric structures with desired properties.

Beyond these major areas, DADMAC finds utility in the Daily Chemical Industry (e.g., in cosmetics and personal care formulations), the Pharmaceutical Industry (often in synthesis or as formulation aids), the Textile Industry (for finishing and treatment), and the Leather Industry (in tanning and finishing processes).
