Detailed use of 1.2-benzisothiazolin-3-one synthesis industrial properties


There are two main synthetic processes for 1,2_benzisothiazolin-3-one:
1) using anthranilic acid as a raw material to prepare dithiobenzoic acid, and then obtaining 1,2-benzisothiazolinone by acid chloride, chlorination and ammoniation;
2) Using ortho-aminobenzonitrile or o-chlorobenzaldehyde as a raw material, reacting with a mercaptan, and then oxidizing and cyclizing to obtain 1,2-benzisothiazolinone.


Benzoisothiazolinone compounds have strong antibacterial and antibacterial properties, low dosage, good compatibility, long-lasting antibacterial properties, excellent environmental performance and broad spectrum of sterilization, and have been highly concerned by the industry. Widely used in agriculture and other industries. Among many isostazolinone compounds, benzisothiazolinone has attracted more and more attention in the field of sterilization and anti-corrosion due to its excellent high temperature and alkali resistance. It has been difficult to play in many conventional antiseptic products. In the special field of effect, it shows unique and excellent effects. At present, the amount of 1,2-benzisothiazolin-3-one BIT in the sterilization of isostazolinone is second only to 2-methyl-4- The role of isothiazolin-3-one (MIT) and 5-chloro-2-methyl-4-isothiazolin-3-one (CMIT) in the field of sterilization has become increasingly important.


BIT is a new type of environmentally-friendly broad-spectrum bactericidal preservative, especially suitable for high temperature environment and alkaline system. It is widely used in the sterilization and anti-corrosion of water and oil systems such as paints, adhesives and polymer synthetic emulsions. The main active ingredient is 1 -2 Benzoisothiazolin-3-one (BIT). It is a new generation of important environmentally friendly industrial sterilization preservatives.


Performance characteristics:
1, with high efficiency and broad spectrum, can effectively kill a variety of bacteria, fungi, mold, yeast, anaerobic bacteria, pseudomonas, Legionella, hydrogen sulfide bacteria, rust bacteria, Bacillus and other fungi , killing plankton and algae, bactericidal and anti-mildew effect broad-spectrum long-term effect, no resistance, use a concentration of 0.1% can achieve a good antibacterial effect.


Widely used in coatings, waterborne polymers, metal cutting fluids, adhesives, inks and other industries. In aqueous systems such as coatings, adhesives, and polymer synthetic emulsions, the concentration is generally 0.1-0.4% (w/w), depending on whether the product is susceptible to microbial attack and the storage environment of the product.


Safety performance: The acute oral lethal dose LD50 of rats reaches 5000mg/kg. It is a non-toxic product.
