What is Methacrylatoethyl trimethyl ammonium chloride (DMC) CAS 5039-78-1?

Methacryloyloxyethyl trimethylammonium chloride (DMC) CAS 5039-78-1 is an important cationic monomer. The following is an introduction to its uses, characteristics and advantages:

Uses of DMC CAS 5039-78-1

1.Water treatment field

(1) Flocculant: DMC can copolymerize with other monomers to form a high molecular weight flocculant, which can effectively remove impurities such as suspended particles, organic matter and heavy metal ions in water. It is widely used in sewage treatment and drinking water purification. Compared with traditional flocculants, it has the advantages of fast flocculation speed and good precipitation effect.

(2) Sludge dewatering agent: DMC CAS 5039-78-1  is used for sludge dewatering treatment, which can quickly separate the water in the sludge, reduce the water content of the sludge, and facilitate the subsequent sludge disposal and transportation.

Papermaking industry

(3) Retention and filtration aid: DMC can improve the retention rate of fillers and fine fibers in the paper production process, while accelerating the filtration speed of pulp, improving production efficiency, and improving the physical properties of paper, such as strength and smoothness.

(4) Paper enhancer: By combining with cellulose in paper, DMC CAS 5039-78-1 enhances the tensile strength, tear strength and folding resistance of paper, thereby improving the quality of paper.

Textile printing and dyeing industry

(5) Antistatic agent: DMC can give textiles good antistatic properties, reduce the problems of dust absorption and entanglement caused by static electricity during processing and use of fabrics, and improve the comfort and performance of textiles.

(6) Dyeing auxiliaries: DMC CAS 5039-78-1 can improve the dyeing rate and dyeing uniformity of dyes, make the dyeing effect more vivid and firm, and reduce the waste of dyes and environmental pollution during the dyeing process.

2.Oil extraction industry

(1) Drilling fluid additive: When added to drilling fluid, DMC can adjust the rheology of drilling fluid, improve the stability and sand carrying capacity of drilling fluid, prevent well wall collapse, protect oil and gas layers, and improve drilling efficiency and quality.

(2) Fracturing fluid additive: During fracturing construction, DMC can increase the viscosity and elasticity of fracturing fluid, improve the fracturing effect, and effectively increase the output of oil and gas wells.

Characteristics of DMC

(1) Cationic properties: DMC contains quaternary ammonium salt cationic groups in its molecular structure, which gives it good cationic activity and can undergo electrostatic adsorption with negatively charged substances. This is its key characteristic for playing a role in many fields.

(2) Polymerization reaction activity: DMC contains carbon-carbon double bonds and can undergo copolymerization with a variety of monomers. By selecting different copolymer monomers and reaction conditions, high molecular polymers with different structures and properties can be synthesized to meet various application requirements.

(3) Water solubility: DMC CAS 5039-78-1 has good water solubility and can be quickly dissolved and evenly dispersed in water, making it easy to carry out various chemical reactions and application operations in aqueous solution systems, and is conducive to use in water treatment, papermaking and other processes using water as a medium.

(4) Stability: DMC has good chemical stability at room temperature and pressure, is not easy to decompose or deteriorate, and is easy to store and transport. However, under extreme conditions such as high temperature, strong acid, and strong alkali, hydrolysis, polymerization and other reactions may occur.

 Advantages of DMC

(1) High efficiency: When DMC is used as a flocculant, retention and filtration aid, etc., only a small amount of DMC can play a significant role, which can effectively improve the treatment efficiency and reduce the cost of use.

Multifunctionality: A variety of functional polymer materials can be prepared through polymerization reaction, which have multiple uses in different fields, such as water treatment agents with multiple functions such as flocculation, decolorization, and sterilization.

(2) Environmental friendliness: Compared with some traditional chemical agents, DMC and its polymers have relatively good degradation performance in the natural environment, less pollution to the environment, and meet the requirements of modern green chemistry and sustainable development.

(3) Good compatibility: DMC can be well compatible with many other chemical substances, and can be used in combination with different types of flocculants, additives, etc. to exert synergistic effects and further improve the treatment effect and performance.
