Diallyldimethylammonium chloride Usage And Synthesis

Description

Diallyldimethylammonium chloride solution (DADMAC) is a hydrophilic quaternary ammonium compound that can be dissolved in an aqueous solution as a positively charged colloid.

Chemical Properties

Colorless to Light yellow to Light orange clear liquid.
Diallyldimethylammonium chloride (DADMAC) and Polydiallyldimethylammonium chloride (polyDADMAC) are contaminants that may be present in potential drinking water sources.
PolyDADMAC is a polymer manufactured from DADMAC. PolyDADMAC is often used to help remove suspended particulates from water. DADMAC has no direct uses, but may be present when polyDADMAC is used.
PolyDADMAC is used in:
Wastewater treatment
Paper making
Textile printing
Silica sand mining

Uses

DADMAC is used as a cationic monomer solution for the fabrication of ion-selective polyelectrolytic anodized aluminium oxide (AAO) membranes which can be used for the development of electrical power generation systems. It may be grafted on carboxymethyl cellulose (CMC) for use as an absorbent for cationic dyes.

Uses

Diallyldimethylammonium chloride (DADMAC) is a viscous, colourless to pale yellow liquid with slight odour. mainly used as cationic monomer in resins production. DADMAC is a quaternary ammonium salt with high density charge and can be dissolved in water very easily. It is non-flammable, non-explosive and stable at room temperature. The polymers occurring by DADMAC reaction is also known as poly-DADMAC and finds its application in a wide range of industrial application.

Application

Diallyldimethylammonium chloride (DADMAC) is a polymer monomer belonging to the quaternary ammonium compounds. The structure of DADMAC is strongly charged and has good water solubility. Therefore, DADMAC and PolyDADMAC are widely used in the field of water treatment as flocculants and flocculation aids, which can effectively flocculate and remove suspended solids, algae, organic matter and other substances. In addition, it can be used as an antimicrobial agent, surfactant or binder in various industrial applications, commonly found in paper, textiles and personal care products.
