Properties

Dodecyldimethylbenzyl ammonium chloride is a colorless or light yellow viscous transparent liquid.

Dodecyl dimethyl benzyl ammonium chloride has high bactericidal and algaecidal ability, low toxicity, no cumulative toxicity, is easily soluble in water, easy to use, not affected by water hardness, and has a strong stripping effect. It is suitable for bactericidal algaecides and stripping agents for circulating cooling water in power plants and large chemical plants. It is used to control the accumulation of mud and scale in the circulating cooling water system and the growth of sulfate-reducing bacteria under the scale. It has good killing and inhibitory effects on heterotrophic bacteria, iron bacteria, sulfate-reducing bacteria, anaerobic bacteria and fungi in the circulating cooling water system, and is better at killing bacteria and algae in oil field injection water. It has the characteristics of broad spectrum, high efficiency, penetration, stripping, low toxicity, good water solubility, and easy use. It has good killing and inhibitory effects on heterotrophic bacteria, iron bacteria, sulfate-reducing bacteria, anaerobic bacteria and fungi in the circulating cooling water system, and is better at killing bacteria and algae in oil field injection water.

Uses

Used as acrylic fiber leveling agent, printing and dyeing fabric retarder, oil field oil well bactericide, cooling water system bactericide and algaecide, medical equipment disinfectant, etc.

Uses

Antimalarial drugs

Uses

Dodecyl dimethyl benzyl ammonium chloride (DDBAC) has low toxicity, no cumulative toxicity, is easily soluble in water, and is not affected by water hardness. Therefore, it is widely used in circulating cooling water systems in the petroleum, chemical, electric power, textile and other industries to control the growth of bacteria and algae in circulating cooling water systems, and is particularly effective in killing sulfate-reducing bacteria. This product can be used as a bactericide and mildew preventer, softener, antistatic agent, emulsifier, conditioner, etc. in the textile printing and dyeing industry.

Production method

Using dodecanol and dimethylamine as raw materials, under the action of high-efficiency catalyst, ammonia is catalyzed to produce dodecanol tertiary amine in one step, and the crude product content can reach 85%. After distillation, more than 95% pure product can be obtained. Alternatively, dodecanol is used to synthesize dodecyl bromide, which is then reacted with dimethylamine to obtain dodecyl dimethyl tertiary amine, and finally reacted with benzyl chloride to obtain benzalkonium chloride.
