Use | It is a kind of cationic surface compatibility agent, which belongs to non-oxidizing bactericide, has broad-spectrum and high-efficiency sterilization and algicidal ability, and can effectively control the propagation of bacteria and algae in water and the growth of slime, and has a good slime stripping effect and a certain dispersion, penetration, at the same time has a certain oil, deodorization ability and corrosion inhibition.
low toxicity, no accumulation of toxicity, and easily soluble in water, is not affected by water hardness, so it is widely used in petroleum, chemical, electric power, textile and other industries in the circulating cooling water system, it is used to control the breeding of bacteria and algae in the cruise cooling water system, and has special effects on killing sulfate reducing bacteria. it can be used as sterilization and anti-toxin agent, softener, antistatic agent, emulsifier and conditioner in textile and dyeing industry. |

yellow waxy solid and colloidal solid. There is aromatic gas, bitter taste. Easy to absorb moisture, soluble in water, slightly soluble in ethanol. With the properties of a typical cationic surfactant, a large amount of foam can be generated when the aqueous solution is stirred. Stable nature, light-resistant, heat-resistant, non-volatile.
with decanediol and dimethylamine as raw materials, under the action of high efficiency catalyst, one-step catalytic ammonia is made into tertiary amine, the crude content can reach 85%, and more than 95% pure product can be obtained by distillation. Alternatively, dodecyl bromide can be synthesized from dodecyl alcohol, reacted with dimethylamine to obtain dodecyl dimethyl tertiary amine, and finally reacted with benzyl chloride to obtain benzalkonium chloride.
is one of the commonly used non-oxidizing bactericides in industrial circulating water treatment. Soluble in water, not affected by water hardness, easy to use, low cost, but also has the corrosion of iron metal, cleaning and stripping slime and remove the function of water odor, it is a pleiotropic agent. The use of conditions directly affect its bactericidal activity, the appropriate increase of pH value, to improve the bactericidal power is beneficial. In circulating cooling water treatment, the general dosage of 85% benzalkonium chloride and 45% 1227 is 50 ~ lOOmg/L; When used as slime stripper, the dosage is 200 ~ 300mg/L. 1227 can be used with other fungicides, such as isothiazolinone, glutaraldehyde, dithiocyanomethane, etc., can play a synergistic effect, but 1227 can not be mixed with anionic surfactants.
non-toxic to the human body, the skin and eye mucosa irritation is small, to avoid direct contact with it. Storage should be kept ventilated, not exposed to the Sun, handling and transport process to prevent leakage.

properties | dodecyl dimethyl benzyl ammonium chloride is a colorless or light yellow viscous transparent liquid. |
use | dodecyl dimethyl benzyl ammonium chloride has high bactericidal and algae killing ability, low toxicity, no cumulative toxicity, easy to dissolve in water, easy to use, not affected by water hardness, and has strong stripping effect. it is suitable for bactericidal algicide and stripping agent of circulating cooling water in power plants and large-scale factories, and is used to control the accumulation of mud in circulating cooling water system and the growth of sulfate reducing bacteria under the mud. It has a good killing and inhibiting effect on heterotrophic bacteria, iron bacteria, sulfate reducing bacteria, anaerobic bacteria and fungi existing in the circulating cooling water system, and has a better killing effect on bacteria and algae in oil field water injection. It has the characteristics of broad spectrum, high efficiency, penetration, stripping, low toxicity, good water solubility and convenient use. It has good killing and inhibiting effects on heterotrophic bacteria, iron bacteria, sulfate reducing bacteria, anaerobic bacteria and fungi existing in the circulating cooling water system, and is used as acrylic leveling agent, dyeing and dyeing fabric retarding agent, oil well bactericide, cooling water system bactericide, medical equipment disinfectant, etc. antimalarial drug dodecyl dimethyl benzylammonium chloride (DDBAC) has little toxicity, no cumulative toxicity, and is easily soluble in water, it is not affected by water hardness, so it is widely used in circulating cooling water systems in petroleum, chemical, electric power, textile and other industries to control the growth of bacteria and algae in the circulating cooling water system, and has special effects on killing sulfate reducing bacteria. This product can be used as a sterilization and antifungal agent and softener, antistatic agent, emulsifier, conditioner, etc. in the textile printing and dyeing industry. This product has low toxicity, no cumulative toxicity, and is easily soluble in water, and is not affected by water hardness. Therefore, it is widely used in circulating cooling water systems in petroleum, chemical, electric power, textile and other industries to control The breeding of bacteria and algae in the circulating cooling water system has special effects on killing sulfate reducing bacteria. This product can be used as a sterilization and antifungal agent and softener, antistatic agent, emulsifier, conditioner, etc. in the textile printing and dyeing industry. |
production method | using decanediol and dimethylamine as raw materials, under the action of a high-efficiency catalyst, ammonia is catalyzed in one step to prepare twelve tertiary amine, the crude content can reach 85%, and more than 95% pure products can be prepared by rectification. Or synthesize dodecyl bromide from dodecyl alcohol, and then react with dimethylamine to obtain dodecyl dimethyl tertiary amine, and finally react with benzyl chloride to obtain benzalkonium chloride. |
