Industrial fungicide - kathon chemical structure formula
First, performance and use
kathon antiseptic is a new type of antiseptic with high efficiency, low toxicity, broad spectrum and high efficiency, which has been widely praised in the world. By breaking the protein bond between bacteria and algae, kathon plays a role in killing and preservative. kathon has a strong inhibition and killing effect on common bacteria, fungi, algae, etc. After contact with microorganisms, kathon can rapidly and irreversibly inhibit their growth, resulting in the death of microbial cells. Therefore, the preservative performance of kathon is beyond doubt.
kathon is a broad spectrum, high efficiency, low toxicity, non-oxidizing biocide. It is widely used in oil field, paper making, pesticide, cutting oil, leather, ink, dye, leather and other industries.
2. Technical indicators
kathon appearance: light yellow transparent liquid;
Density (20℃)g/cm3≥1.30;
Solubility: completely miscible with water;
Effective content: ≥14%;
PH(original solution) : 2.0 ~ 4.0.
Third, the use of methods
kathon is widely used in iron and steel smelting, oil field water injection, thermal power generation, paper making, oil refining, chemical industry, textile, industrial cleaning, cutting oil water-based coatings, daily chemical and other fields. kathon has a strong killing and inhibiting effect on bacteria such as sulfate-reducing bacteria, sludge molding bacteria, iron-oxidizing bacteria, mold, yeast and algae. Note: Cannot be used in circulating water systems containing sulphides.
Fourth, the advantages of kathon
1, the use of cassone low concentration, long duration of efficacy, no foam;
2, kathon is suitable for high and low PH value, a wide range of application, PH value in 3 ~ 9.5 has no effect on the sterilization effect;
3, high efficiency, broad spectrum, can kill and inhibit a variety of microorganisms, mold and algae;
4, can effectively prevent the formation of mud;
5, easy to use, safe, can be directly added;
6, kathon is a green sterilization preservative, conducive to environmental protection, can be self-degraded into non-toxic substances, long-term use will not cause environmental harm.
7, good compatibility, can be compatible with a variety of anionic, cationic, non-ionic additives, can also be used with other fungicides, especially with the compound use of quaternary ammonium salt is better.
5. Synthesis process
The synthesis of isothiazolinone starts from the basic raw material and is divided into three steps:
1. Preparation of dimethyl dithiodipropionate
2. Preparation of dimethyl dithiodipropionamide
3. Preparation of isothiazolinone
6. Packaging and storage
Kathon adopts 25KG/ plastic drum or 250KG plastic drum packaging
Safety and protection
kathon is corrosive and irritating to the skin and eyes. Wear protective glasses and rubber gloves when operating. Once in contact with the skin and eyes, rinse immediately with plenty of water.
