Benzyl Ammonium Chloride
Benzyl ammonium chloride is currently the most widely used and cost-effective class of fungicides. This kind of quaternary ammonium salt has low toxicity, no accumulation toxicity, and is easily soluble in water, and is not affected by water hardness. Therefore, it is widely used in the circulating cooling water systems of petroleum, chemical, electric power, textile, and other industries to control algae grows in the circulating cooling water system.
The most commonly used benzyl ammonium chloride is dodecyl dimethyl benzyl ammonium chloride. Dodecyl dimethyl benzyl ammonium chloride is slightly soluble in ethanol, soluble in water, and the aqueous solution is weakly alkaline. A large amount of foam is generated when shaking and long-term exposure to the air is easy to absorb moisture. When stored at rest, fisheye crystals precipitate. It is stable in nature, resistant to light, pressure, heat, and volatility. Usually, the industrial product is an aqueous solution containing 40% or 50% active ingredient, which is a colorless or light yellow viscous liquid with an aromatic odor and a bitter taste.
Dodecyl dimethyl benzyl ammonium chloride is a cationic surfactant. It is a non-oxidizing fungicide with broad-spectrum and high-efficiency bactericidal and algae-killing ability. It can effectively control the growth of bacteria and slime in water. And dodecyl dimethyl benzyl ammonium chloride has a good slime stripping effect and a certain dispersion, osmosis, and has a certain degreasing, deodorizing ability, and corrosion inhibition. There are two main products of benzyl ammonium chloride, they are hydrogenated tallow benzyl dimethyl ammonium chloride and di(hydrogenated tallow)benzyl methyl ammonium chloride.
