CAS 26172-55-4

Isothiazolinone is a kind of excellent water treatment agent with good miscibility. It can be miscible with various corrosion inhibitors, scale inhibitors and dispersants such as chlorine, most anionic, cationic and non-ionic surfactants. The commodities on the market are usually a mixture of 5-chloro-2-methyl-4-isothiazoline-3-one (CMI) and 2-methyl-4-isothiazoline-3-one (MI), and metal nitrite will also be added Or metal nitrate, improve stability and prevent decomposition. Isothiazolinone has a killing effect by breaking the bond between bacteria and algae protein. After contacting with microorganism, it can quickly and irreversibly inhibit its growth, thus leading to the death of microbial cells. For common bacteria (sulfate reducing bacteria, sludge forming bacteria), fungi (iron oxide bacteria, mold, yeast bacteria), it can not only reduce the growth of bacteria, but also reduce the growth of bacteria , algae and so on have strong inhibition and killing effect. It has the characteristics of high killing efficiency, good degradation, no residue, safe operation, good compatibility, strong stability and low cost. At high dosage, it has significant effect on biological slime stripping. At present, it has been widely used in iron and steel smelting, oilfield water injection, thermal power generation, paper making, oil refining, chemical industry, light textile, industrial cleaning, pesticide, cutting oil-water coating, daily chemical industry, ink, dye, leather and other fields.
