Methylene Dithiocyanate Usage and Synthesis:

Dithiocyanate Melting point 100-104 ℃, soluble in 1.4-dioxane, N.N-dimethylformamide, slightly soluble in other organic solvents, slightly soluble in water, solubility in water about 0.4% solubility in water, stable under acidic conditions. It has good effect of antisepsis, sterilization and algaecide. The solubility in room temperature water is 2300ppm. It is sensitive to pH and hydrolyzes quickly above pH=8. Dithiocyanomethane is an efficient, broad-spectrum bactericide and algaecide, with high efficiency in killing the main bacteria, fungi and algae in circulating water. It is a highly effective, broad-spectrum fungicides and algaecide, and has a long duration of efficacy.

Pharmacokinetics of Methylene Dithiocyanate:

An excess of sodium thiocyanate (or sodium thiocyanide) was added to the reaction kettle with dichloromethane under pressure, and stirring was turned on while the temperature was increased to 80-100°C. After the reaction is finished, retrieve After the reaction, the dichloromethane is collected and the solid-liquid phase is separated to obtain the crude dithiocyanomethane. As long as the mass concentration of 0.3mg/L of dithiocyanomethane is maintained in water, it can effectively kill microorganisms. It is a non-oxidizing bactericide. The bactericidal and antibacterial effect of dithiocyanomethane is related to the ph value of water, and it has a good and stable bactericidal effect in the range of ph value from 6 to 7. It has good stabilization effect in the range of 6-7. When the ph value is higher than 8.5, it will be easily decomposed and the bactericidal effect will be affected. Since dithiocyanomethane is insoluble in water, it cannot be used directly. It is usually used in combination with solvents, dispersants or other bactericidal compounds.

Clinical Application of Methylene Dithiocyanate:

Methylene dithiocyanate has been used for a long time for sterilization, wood preservative, algaecide and anti-scaling. Dithiocyanate: Dithiocyanomethane has been used for a long time for sterilization, wood preservative, algaecide, anti-scaling, etc. Nowadays, it is mainly used to make bactericide; used as anti-mildew and preservative for leather, wood, etc., used in rice seed dipping to prevent various leaf spot diseases; used in swimming pool water sterilization; used in industrial circulating water treatment Used in oil fields to reduce oil pollution, prevent clay swelling and sterilization and scale prevention, increase production; widely used in water treatment, sterilization and algae; used as fish medicine, widely used in aquaculture It is used in the manufacture of cables, wires, tires and other rubber products; it is made into emulsified oil and used in the treatment of rice and wheat seeds to prevent and control seed-borne bacteria, fungi and nematode diseases. In addition We also provide all kinds of insecticides, herbicides, etc.
